515 Athalia
Athalia (minor planet designation: 515 Athalia), provisional designation , is a carbonaceous Themistian asteroid from the outer regions of the asteroid belt, approximately 40 kilometers in diameter. It was discovered on 20 September 1903, by German astronomer Max Wolf at the Heidelberg Observatory in southwest Germany. The asteroid was named after the ancient Judahite queen Athaliah. Orbit and classification Athalia is a Themistian asteroid that belongs to the Themis family (), a very large family of carbonaceous asteroids, named after 24 Themis. It orbits the Sun in the outer main belt at a distance of 2.6–3.7 AU once every 5 years and 6 months (2,016 days). Its orbit has an eccentricity of 0.17 and an inclination of 2°. The body's observation arc begins at Heidelberg with its official discovery observation in 1903. Physical characteristics Spectral type In the SMASS classification, the asteroid is a Cb-subtype, that transitions between the carbonaceous C-type to the B-type asteroids. In the Tholen classification, no type could be assigned to Athalia since its spectrum was inconsistent as it resembled that of an S-type asteroid, while its albedo was far too low for that spectral type. Rotation period In October 2015, a rotational lightcurve of Athalia was obtained from photometric observations by American astronomer Frederick Pilcher at the Organ Mesa Observatory () in New Mexico, United States. Lightcurve analysis gave a well-defined rotation period of 10.636 hours with a brightness amplitude of 0.22 magnitude (). Diameter and albedo According to the surveys carried out by the Japanese Akari satellite, the Spitzer Space Telescope and the Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Athalia measures about 40 kilometers in diameter and its surface has an albedo of about 0.03 to 0.04. The Collaborative Asteroid Lightcurve Link adopts the results obtained by the Infrared Astronomical Satellite IRAS, that is, an albedo of 0.039 and a diameter of 38.22 kilometers based on an absolute magnitude of 11.23. Naming This minor planet was named after Athaliah (Athalia), the daughter of King Ahab and Queen Jezebel of Israel. The murderous queen of the ancient Kingdom of Judah was the only woman to ever rule the Hebrew kingdoms. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 ().

517 Edith
Edith (minor planet designation: 517 Edith), provisional designation , is a carbonaceous background asteroid from the outer regions of the asteroid belt, approximately 83 kilometers in diameter. It was discovered on 22 September 1903, by American astronomer Raymond Dugan at the Heidelberg-Königstuhl State Observatory in southwest Germany, who named it after his sister Edith Eveleth. Orbit and classification Edith orbits the Sun in the outer main-belt at a distance of 2.6–3.7 AU once every 5 years and 7 months (2,050 days). Its orbit has an eccentricity of 0.18 and an inclination of 3° with respect to the ecliptic. The body's observation arc begins at Heidelberg, five days after its official discovery observation (first recorded observation at the MPC). Physical characteristics In the Tholen taxonomy, Edith is an X-type asteroid. Due to its very low albedo, a more specific P-type is derived by the LCDB, while a spectroscopic survey of Tholen X-type asteroids characterizes Edith as a C-type asteroid. Rotation period In October 2009, the best-rated rotational lightcurve of Edith was obtained from photometric observations by French amateur astronomer Maurice Audejean at his Chinon Observatory () in Chinon, France. Lightcurve analysis gave a well-defined rotation period of 9.2747 hours with a brightness variation of 0.16 magnitude (), indicating that the body is rather spheroidal. Additional measurements of the asteroid's period were made by French amateur astronomers René Roy and Laurent Bernasconi, as well as by American astronomer Robert Koff at his Antelope Hills Observatory in Bennett, Colorado () and by Alan W. Harris of the Earth and Planetary Physics Group at JPL in the 1980s (). Diameter and albedo According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Edith measures between 79.72 and 111.89 kilometers in diameter and its surface has a low albedo between 0.026 and 0.05. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0397 and a diameter of 83.24 kilometers based on an absolute magnitude of 9.52. Naming This minor planet was named by the discoverer after his sister Edith Eveleth (née Dugan). The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (). Edith Eveleth also proposed and prepared the naming citation for Raymond Dugan's first discovery, .

520 Franziska
Franziska (minor planet designation: 520 Franziska), provisional designation , is an Eoan asteroid from the outer regions of the asteroid belt, approximately 27 kilometers in diameter. It was discovered on 27 October 1903, by astronomers Max Wolf and Paul Götz at the Heidelberg-Königstuhl State Observatory in southwest Germany. The origin of the asteroid's name is unknown. Orbit and classification Franziska is a member the Eos family (), the largest outer-belt asteroid family consisting of nearly 10,000 known members. It orbits the Sun at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,902 days). Its orbit has an eccentricity of 0.11 and an inclination of 11° with respect to the ecliptic. The body's observation arc begins one day after its official discovery observation at Heidelberg. Physical characteristics In the Tholen classification, Franziskas spectral type is ambiguous. It is closest to a common C-type, and somewhat similar to the rare and also carbonaceous G-type asteroids (CG). The spectrum has also been labelled as "unusual" by Tholen (U). For a carbonaceous asteroid, it has a relatively high albedo (see below). Rotation period In December 2013, a rotational lightcurve of Franziska was obtained from photometric observations by American astronomer Frederick Pilcher at the Organ Mesa Observatory in New Mexico. Lightcurve analysis gave a well-defined rotation period of 16.507 hours with a brightness variation of 0.35 magnitude (). The result supersedes Richard Binzel's previously obtained lightcurve from May 1985, which gave a period of 14.0 hours and an amplitude of 0.53 magnitude (). Poles Two lightcurves, published in 2016, using modeled photometric data from the Lowell Photometric Database (LPD) and other sources, gave a concurring period of 16.5044 and 16.5045 hours, respectively. Each modeled lightcurve also determined two spin axes of (122.0°, −50.0°) and (301.0°, −59.0°), as well as (282.0°, −79.0°) and (114.0°, −45.0°) in ecliptic coordinates (λ, β), respectively. Diameter and albedo According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Franziska measures between 25.261 and 28.67 kilometers in diameter and its surface has an albedo between 0.1226 and 0.147. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1143 and a diameter of 28.61 kilometers based on an absolute magnitude of 10.69. Naming Any reference of this minor planet's name to a person or occurrence is unknown. "Franziska" is a common German female name and was proposed by the second discoverer Paul Götz in 1905 (). Unknown meaning Among the many thousands of named minor planets, Franziska is one of 120 asteroids, for which no official naming citation has been published. All of these low-numbered asteroids have numbers between and and were discovered between 1876 and the 1930s, predominantly by astronomers Auguste Charlois, Johann Palisa, Max Wolf and Karl Reinmuth.

522 Helga
Helga (minor planet designation: 522 Helga), provisional designation 1904 NC is a large main belt asteroid (minor planet). It was discovered in 1904 by Max Wolf in Heidelberg. Helga is notable for being the first such object to be shown to be in a stable but chaotic orbit in resonance with Jupiter, its Lyapunov time being relatively short, at 6,900 yr. Despite this, its orbit appears to be stable, as the eccentricity and precession rates are such that it avoids close encounters with Jupiter. It forms part of the Cybele asteroid group. 522 Helga was "named by Lt. Th. Lassen, orbit computer" according to Paul Herget's The Names of the Minor Planets (note that computer does not refer to a personal computer, i.e. a machine, but rather to a person actually doing the necessary calculations).

525 Adelaide
Adelaide (minor planet designation: 525 Adelaide) is an S-type asteroid belonging to the Flora family in the Main Belt. It was discovered 21 October 1908 by Joel Hastings Metcalf. Previously, the object A904 EB, discovered 14 March 1904 by Max Wolf, had been named 525 Adelaide but was subsequently lost. When it was rediscovered 3 October 1930 by Sylvain Arend as 1930 TA, it was named 1171 Rusthawelia. Some 28 years passed before the two objects were realized to be the same. 1930 TA retained the name Rusthawelia (and discovery credited to Arend); the name 525 Adelaide was reused for the object 1908 EKa. Another confusion occurred in 1929, one year before Arend's discovery, when American astronomer Anne Sewell Young thought to have found long-lost "Adelide", when in fact she mistook the asteroid for comet 31P/Schwassmann–Wachmann that had a very similar orbital eccentricity.

Rezia (minor planet designation: 528 Rezia) is a minor planet orbiting the Sun. It was discovered by Max Wolf on March 20, 1904. It is named for a character in the 1826 opera Oberon by Carl Maria von Weber. Among the 248 discoveries by Wolf, he also discovered 527 Euryanthe and 529 Preziosa on the same day. The mostly likely source for the name of the asteroid is the character Rezia in Carl Maria von Weber's opera Oberon, given that around 1904 the astronomer was frequently using the names of female opera characters for the asteroids he discovered. In 1907, August Kopff's November 1 sighting of the provisionally designated 1907 AQ was instead determined to be 528 Rezia. In 1987, it was reported that Rezia has a flat spectrum and IRAS albedo value pv=0.54 ± 0.0004, which is very dark and consistent with a C-type asteroid.

Praxedis (minor planet designation: 547 Praxedis), provisional designation , is a Postremian asteroid from the central regions of the asteroid belt, approximately 52 kilometers in diameter. Description The asteroid was discovered on 14 October 1904, by astronomer Paul Götz at the Heidelberg-Königstuhl State Observatory in southwest Germany. It was named from literature after the character "Praxedis" in Joseph Victor von Scheffel's historical romance Ekkehard (1857). The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (). Praxedis is a member of the Postrema family (), a mid-sized central asteroid family of little more than 100 members. It orbits the Sun in the central main-belt at a distance of 2.1–3.4 AU once every 4 years and 8 months (1,690 days). Its orbit has an eccentricity of 0.24 and an inclination of 17° with respect to the ecliptic. In the Tholen classification, Praxedis has an ambiguous spectral type, closest to an X-type and somewhat similar to that of a darker D-type asteroid. In the SMASS classification it is a Xk-subtype that transitions from the X- to the rare K-type asteroids. According to the survey carried out by NASA's Wide-field Infrared Survey Explorer, Praxedis measures 52.462 kilometers in diameter and its surface has an albedo of 0.101.

https://en.wikipedia.org/wiki/555%20Norma
555 Norma
Norma (minor planet designation: 555 Norma), provisional designation , is a background asteroid from the outer regions of the asteroid belt, approximately 33 kilometers in diameter. It was discovered on 14 January 1905, by German astronomer Max Wolf at Heidelberg Observatory in southwest Germany. The asteroid was named after the title character of Bellini's opera Norma. Classification and orbit Norma is a background asteroid, located near the region occupied by the Themis family, a prominent family of outer-belt asteroids with nearly coplanar ecliptical orbits. It orbits the Sun at a distance of 2.7–3.7 AU once every 5 years and 8 months (2,078 days). Its orbit has an eccentricity of 0.15 and an inclination of 3° with respect to the ecliptic. The body's observation arc begins at Heidelberg in March 1911, more than six years after its official discovery observation. Physical characteristics Spectral type In the SMASS classification, Norma is a B-type asteroid. These types of asteroids have a featureless surface that displays magnesium-rich silicates, which likely accounts for the relatively high albedo as an outer-belt asteroid. Norma surface consists of more than 50% amorphous magnesium pyroxenes based on data collected with the Subaru Telescope. Photometry In April 2007, a first rotational lightcurve of Norma was obtained from photometric observations by French amateur astronomer Pierre Antonini. Lightcurve analysis gave a rotation period of 30.6 hours with a brightness variation of 0.2 magnitude (). However more recent observations by two American astronomers have since superseded this result. In December 2011, Robert Stephens at the Santana Observatory obtained a lightcurve that gave a period 19.55 hours and a brightness amplitude of 0.06 magnitude (), while Frederick Pilcher measured a period of 19.508 hours with an amplitude of 0.25 at the Organ Mesa Observatory in November 2016. Diameter and albedo According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Norma measures between 27.89 and 40.11 kilometers in diameter and its surface has an albedo of between 0.063 and 0.119. The Collaborative Asteroid Lightcurve Link (CALL) agrees with IRAS, and derives an albedo of 0.0528 and a diameter of 40.02 kilometers based on an absolute magnitude of 10.8. CALL also assumes Norma to be a C-type asteroid (rather than a B-type) due to its derived low albedo and the general spectral type of the Themis family. Naming This minor planet was named for the principal female character of the opera Norma by Italian composer Vincenzo Bellini (1801–1835). In the opera, Norma is a high priestess of the Druids. In 1955, the official naming citation was published by Paul Herget in The Names of the Minor Planets () References External links Asteroid Lightcurve Database (LCDB), query form (info ) Dictionary of Minor Planet Names, Google books Asteroids and comets rotation curves, CdR – Observatoire de Genève, Raoul Behrend Discovery Circumstances: Numbered Minor Planets (1)-(5000) – Minor Planet Center 000555 Discoveries by Max Wolf Named minor planets 000555 19050114

589 Croatia
Croatia (minor planet designation: 589 Croatia), provisional designation , is a dark asteroid and parent body of the Croatia family, located in the outer regions of the asteroid belt, approximately 88 kilometers in diameter. It was discovered in 1906, by astronomer August Kopff at Heidelberg Observatory, and later named for the independent country of Croatia, then part of Austria-Hungary. Discovery The asteroid was discovered on 3 March 1906, by German astronomer August Kopff at the Heidelberg-Königstuhl State Observatory in southwest Germany, with the use of the photographic method. In the moment of the discovery, the asteroid was 12.5mv and was in the constellation of Virgo. The discovery was published in the Astronomische Nachrichten magazine, in the article wrote by Professor Wolf. Later, some astronomers (Johann Palisa, Karl Lohnert and some others) were making measurements for the purpose of determining the orbital elements. From these measurements P. V. Neugebauer from Berlin and M.S. Mello and Simas from Trafaria (Lisbon) had independently determined the first orbital elements. Observations had continued, and among observers there were A. Kopff, E. Bianchi, A. Abetti, G. Zappa, P. Chafardet, E. Millosevich, J. Palisa, and some others. Observations were made from Berlin, Copenhagen, Rome, Arcetra and some other Italian cities. Orbit and classification Croatia is the parent body of the Croatia family (), a small asteroid family of less than 100 known members. It orbits the Sun in the outer main belt at a distance of 3.0–3.3 AU once every 5 years and 7 months (2,032 days; semi-major axis of 3.14 AU). Its orbit has an eccentricity of 0.04 and an inclination of 11° with respect to the ecliptic. The body's observation arc begins at Heidelberg, sixteen days after its official discovery observation. Physical characteristics In the Tholen classification, Croatia is ambiguous, closest to a carbonaceous C-type and somewhat similar to that of an X-type asteroid, while the Wide-field Infrared Survey Explorer (WISE) characterized it as a primitive P-type asteroid. Nesvorný determined the overall spectral type for the Croatia family to be that of an X-type. Rotation period In July 2013, the so-far best-rated rotational lightcurve of Croatia was obtained by astronomers Romain Montaigut, Arnaud Leroy, Raoul Behrend, René Roy, Donn Starkey, Maurice Audejean, Roberto Crippa and Federico Manzini. Lightcurve analysis gave a longer-than average rotation period of 24.821 hours with a brightness variation of 0.25 magnitude (). The result supersedes photometric observations by Brian Warner and by astronomers at the Palomar Transient Factory, which measured a shorter period of 11.7 and 16.385 hours with an amplitude of 0.16 and 0.32, respectively (). Diameter and albedo According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's WISE telescope, Croatia measures between 84.44 and 96.491 kilometers in diameter and its surface has an albedo between 0.041 and 0.06. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0577 and a diameter of 87.66 kilometers based on an absolute magnitude of 9.0. The radius of (probably) 28.452 km (and, consequently, the superficial area of 2543.2 km2, and equatorial circumference of 89.385 km) were determined by use of Argelander's Method. Naming This minor planet was named for the country of Croatia, then part of Austria-Hungary, after the suggestion made by astronomer Max Wolf. It also honors the foundation of the Astronomical Observatory of the Croatian Natural Sciences Society (Zagreb Observatory) in Zagreb.

596 Scheila
Scheila (minor planet designation: 596 Scheila) is a main-belt asteroid and main-belt comet orbiting the Sun. It was discovered on 21 February 1906 by August Kopff from Heidelberg. Kopff named the asteroid after a female English student with whom he was acquainted. Overview On 11 December 2010, Steve Larson of the Catalina Sky Survey detected a comet-like appearance to asteroid Scheila: it displayed a "coma" of about magnitude 13.5. Inspection of archival Catalina Sky Survey observations showed the activity was triggered between 11 November 2010 and 3 December. Imaging with the 2-meter Faulkes Telescope North revealed a linear tail in the anti-sunward direction and an orbital tail, indicative of larger slower particles. When first detected it was unknown what drove the ejecta plumes. Scheila's gravity is too large for electrostatics to launch dust. Cometary outgassing could not be ruled out until detailed spectroscopic observations indicated the absence of gas in Scheila's plumes. Observations by the Hubble Space Telescope and the Neil Gehrels Swift Observatory's ultraviolet-optical telescope make it most likely that Scheila was impacted at ~5 km/s by a previously unknown asteroid ~35 meters in diameter. Each asteroid the size of Scheila might be hit by an impactor 10–100 meters in diameter approximately every 1000 years, so with 200 asteroids of this size or bigger in the asteroid belt, we can observe a collision as often as every 5 years. As a consequence of the 2010 impact, the surface spectrum of Scheila changed, from a moderately red T-type spectrum to a more reddish D-type spectrum, showing how "fresh" material weathers over time in space. This is similar to laboratory experiments done on the Tagish Lake meteorite. Scheila last came to perihelion on 2012 May 19.
