Yes, but that would be dictated by how fast can it spin before shattering into pieces. So mostly gravity/composition thing, I'd imagine. Many things in solar systems are (postulated to) derive from the rotation of the protoplanetary disk, via conservation of angular momentum - however, planets can also get spun up or down after forming by e.g. collisions with other objects, including extra-system objects.

Just realized, I meant orbit speed and not rotation aeound the planets axis. Shouldn't write in parallel to meetings... Your answer was very interesting so, thank you!

I see! In the other case, the answer is: velocity vector determines the orbit. For any given point at any given orbit, there's only one valid velocity vector relative to the star (direction and magnitude) - tweaking it tweaks the shape of the orbit.
One of the best way to get an intuition for orbits is to play Kerbal Space Program for a few hours :).

Going back to my buried physics knowledge, that is quite logic. Thanks again!
I am just afraid to touch Kerbal Space Program, I really cannot afford another time sink at the moment!
As one time ovner of a Star Wars RPG PC whos secret super weapon was his tremendous Astrogation skill, I really should so I guess!
