Question: How much of a tilt is the planet Mercury on?
Answer: The planet mercury in fact has 0o (zero degrees) of tilt. Mercury rotates on a vertical axis which means it experiences no seasons due to the same latitudinal area of the planet directly facing the sun all year round.
On Mercury each year lasts 88 Earth days and each day lasts 59 Earth days so it orbits the sun quite fast, mainly due to it having the closest orbit but it spins on it’s axis very slowly.
However as there are no seasons, if you were able to live on Mercury the years would be rather irrelevant anyway.
Mercury is the innermost planet in the solar system and the only one spinning on a tilt of 0o.
