The orbits are accurately modeled, and I'm trying to try catch one in this game.
The orbits in SpaceEngine are somewhat lacking in accuracy for solar system objects, so transits and eclipses will often not happen when and where they should. SpaceEngineer has already said he plans to address this in a future release.
If you want to see Venus backdropped by the sun though, you could always just fly to it and back away from it until you are at Earth's distance and zoom in
