This is a navigable solar system. The orbits of the planets are not accurate to real life. To use the rocket, make sure the body to follow is zero, then hold the left mouse button or hold on the screen to start moving. The rocket automatically points to the mouse. You can explore every terrestrial planet in the solar system, and land on them too! You can use turbo mode to speed it up.
Planned Updates (if i continue working on this): Higher detail planets, even more planets and moons, speeding the simulation up, fuel limit, planting flags, space center buildings, atmosphere effects, launching multiple rockets, VAB (or preset rockets), and more!
