What planet barely spins around its axis?

Answer 1

Mercury executes a complete, 360-degree rotation on its axis every 58.6 earth-days ...

very roughly double the rotation period of earth's moon.

We're unable to find a definition of 'barely' in our Glossary of Astronomical Terms.

Answer 2

Most planets rotate in very nearly the same plane as their orbit. (For example the Earth's rotation is off by 23 degrees from its orbital axis). The axis of the planet Uranus, however, is off by 98 degrees from its orbit. Thus as viewed from the perspective of "orbital plane up", it could be said to be rotating "on its side".

(Some sources say equivalently that Uranus is tilted 82 degrees, and is rotating backwards.)

As a result of the extreme tilt, Uranus experiences seasons unlike those of any other planet. Essentially, the arctic circles and tropic circles are switched. This means that during the summer, the polar region receives more sunlight than the equator.

Answer 3

There is one planet that barely spins on its own axis. That planet is Venus. It barely spins on its axis, and it has a retrograde rotation.

Answer 4

Venus. Venus takes 243 days to spin on its axis relative to the background stars. It takes less time to orbit the sun, which takes 224.7 days.

Answer 5

Venus. It takes about 243 Earth days to rotate once.
