HORIZONS
The Jet Propulsions Laboratory's HORIZONS system is used to generate ephemerides for solar-system bodies. All state vectors for solar system scenarios were obtained from HORIZONS. Learn More
NASA Exoplanet Archive
The NASA Exoplanet Archive is an online astronomical exoplanet and stellar catalog and data service that collates and cross-correlates astronomical data and information on exoplanets and their host stars, and provides tools to work with these data. All the orbital elements used to create the exoplanetary simulations were obtained from the Exoplanet Archive. Learn More
3D Asteroid Catalogue
3D Asteroid Catalogue is an interactive catalogue that contains 3D models, orbital and physical parameters and current orbital position of known minor bodies. All asteroid models used in Gravity Simulator were obtained from the 3D asteroid Catalogue. Learn More
NASA 3D Resources
A growing collection of 3D models, textures, and images from inside NASA. All spacecraft 3D models used in Gravity Simulator, unless otherwise noted, were obtained from NASA 3D Resources. Learn More
Uncharted
A 3D visualization of Earth’s solar neighborhood out to 75 light years, rendered in the browser using WebGL. The procedural star shaders used in Gravity Simulator were written by Ben Podgursky for Uncharted. Learn More
Poliastro
Poliastro is an open source pure Python package dedicated to problems arising in Astrodynamics and Orbital Mechanics, such as orbit propagation, solution of the Lambert's problem, conversion between position and velocity vectors and classical orbital elements and orbit plotting, focusing on interplanetary applications. The Lambert Solver in Gravity Simulator, which was written by Hugo Granström, is based the Poliastro implementation. Learn More
Robert Vanderbei
Robert Vanderbei is a Professor in the Department of Operations Research and Financial Engineering at Princeton University. The state vectors for the scenarios that deal with n-body choreographies were obtained from his website. Learn More
