## **Dataset Summary**
This dataset contains a comprehensive set of synthetic data for an interplanetary mission to **624 Hektor**, modeled using a Type II Hohmann transfer orbit. It features:
- **LEO Departure** and heliocentric trajectory phases.
- **Jupiter gravity assist** flyby.
- **Electric propulsion** thrust arcs.
- Final insertion at 624 Hektor on **March 18, 2032**.
The dataset is ideal for machine learning tasks related to orbital mechanics, low-thrust mission optimization, and multi-body transfer simulation.
