Does SpaceEngine simulate orbital motion accurately?

I just found out about this amazing application on Reddit. I'm looking forward to trying it out once I get my new computer up and running. I have a question about how SpaceEngine simulates the motion of all the planetary bodies. Are the effects of gravity modeled reasonably accurately or taken into account? I guess it would be easy to simulate the orbits of real bodies correctly since they are already well known but what about the procedurally generated ones.

Thanks for your answer!

I'm pretty sure all planets have realistic orbits, yes, with the possible exception of old systems with a planet with a highly elliptic orbit. All Solar System bodies certainly have realistic orbits, and those in procedural systems I checked do so too.

I occasionally stream at Sometimes SE, sometimes other games.

Hello JimG, welcome to the forum. Bodies in SpaceEngine follow simple Keplerian orbits, which are quite accurate, but not 100% (this would not be apparent for procedural systems though). In a future version of SpaceEngine the VSOP87 model of Solar system orbits will be implemented, giving very high fidelity in orbital positions for Solar system objects.
