What is mecury's rotation?

Answer 1

The planet Mercury spins slowly west to east, once every 58.64 Earth days.

*Because it is also going around the Sun every 88 Earth days, an observer on Mercury's surface would experience a sunrise or sunset only once every 176 Earth days. The slow, coordinated turning keeps any point on the planet exposed to the Sun for two entire orbits before finally facing away for two orbits!

Answer 2

A solar day on Mercury lasts about 176 Earth days, which is about twice as long as Mercury's orbital period, (roughly 88 Earth Days). As a result, a Mercury year is about 0.5 Mercury days long, and one Mercury day lasts approximately two Mercury years.

Answer 3

Mercury is the innermost and smallest planet in the Solar System, orbiting the Sun once every 87.969 Earth days hence a Mercuric "year" is less than three months on Earth. It goes round the sun in the same direction as all the other planets in the solar system.

For many years it was thought that Mercury was synchronously tidally locked with the Sun (rotating once on its axis for each orbit and thus always keeping the same face directed towards the Sun (like our the Moon always faces the Earth)).

However, we have since discovered that the planet has a 3:2 spin--orbit resonance, rotating three times for every two orbits it makes around the Sun.

Answer 4

Mercury's rotation period is 59 Earth days.

Answer 5

The planet Mercury, closest to the Sun, takes 58 days to rotate, which is a bit weird; Mercury's YEAR is only 88 days.

Answer 6

About 58.5 Earth days.
