If the planet were smaller would it still be possible to have a 24 hour day?
Asking it a different way for more clarity....
If the size of the planet is different but I still want a 24 hour day, what else (if anything) would I need to change to my hypothetical planet to make a 24 hour day possible. Or can I simply change the rotational speed of the planet without having to change anything else... In other words, would changing the rotational speed cause other problems (gravitational shifts, weather problems, etc.) or can I simply have a smaller planet and set the rotational speed at whatever I need to ensure the 24 hour day without any other consequences.
If there is a consequence to adjusting the rotational speed, is there anything that can conteract that (such as the presence of another moon or different distant from the sun or other factors.)
