At the Earth's equator a person would have to run 1,037 miles/hour to keep up with the Sun. Obviously impossible.
Name the bodies in the solar system (there is more than one) where a running human could, in theory, keep up with the Sun on the body's equator. Help me find the answer please

You asked basically that same question here... and an answer was given.

You can do the math using the rotation speed of the planet or moon along with it's diameter.

Here you'll find that info for the planets and their moons:
