Here you can see how it is done, you can add all the planets and even add each planet speed of rotation around the sun, or as I did, I've speed it all up with Mercury doing 1 rotation around the sun in 1 second, from there I calculated rotation speed of all other planets in relation to Mercury (basically calculated how much slower is each planet rotating than Mercury) and multiplied it by 1000000 microseconds (1 second, used microseconds, as time objects can only be integers), so have all planets rotating in proportion to Mercury down to accuracy of microsecond. For example, Pluto (okay dwarf planet) rotates more than 1000 times slower around the sun than the Mercury.

Though there are no moons, guess, that would you need to do your self, was thinking about it, it would be fun, but I ended up on this by accident so was just playing with it for fun
