Does SpaceEngine simulate orbital motion accurately?

| Hi,
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.

| 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.
