Here is a fun animation that will help you to understand the relative rpms of the planets.

Comparing the rotations of objects in the Solar System. Just look at them lol.✨🪐

To everyone that's confused, the planet Venus rotates very very slowly, with a single revolution taking about 243 Earth days, and Mercury rotates slowly, but not as slow as Venus.

@futurebird TIL that Mercury ISN’T tidally locked — but Venus is!! But if it’s rotating the “wrong way”, then how can it be tidally locked?!
@mike @futurebird Venus isnt tidally locked, it just has a very long day. Mercury used to be believed to be tidally locked, but it's actually in resonance. one solar day lasts 2 years. It just happened both of the first observations of its surface happened in the same part of the resonance.
