Orbital Gravity
Orbital Gravity is a complete Unity project. The main part of the project is the implementation of the famous Newtonian celestial mechanics. It’s a plain gravity driven simulation of celestial body movements.
Just Gravity
The planetary movements are not based of any geometrical astronomy, which means that the simulation is a classical n-body problem with no Kepler path motions. If you change the mass of a body being part of the system, every celestial body gets affected immediately.
HQ Planets
The asset includes each planet of our solar system with high-resolution PBR-textures.
