How many earth days do mercury moves around the sun?

Mercury to orbit around the Sun; a typical year on Mercury would take 88 Earth days. Because of Mercury's ever changing distance from the sun and its 3:2 spin-orbit resonance the temperature on Mercury's surface is complex and varied.


Does planet mercury rotate about its own axis?

Yes, the planet Mercury rotates on its own axis, as do all the known planets. Mercury's rotation is peculiar in that it evidences spin-orbit resonance, rotating three times for every two orbits around the Sun, an effect stabilized by the eccentricity of its orbit.


Who of all the planets in our solar system has the fastest speed?

What is the difference of orbit and spin?

An orbit is where something spins and goes in a circle, a spin is just a spin....


How many days does it take mercury to rotate?

It takes about 58.6 Earth days.


What is one interesting feature of mercury?

Because of the periods of Mercury's orbit and spin, a year (complete orbit around the sun) on Mercury is about 88 Earth days long, while a day (time for the Sun to appear in the same place in the sky) is twice that length, at about 176 Earth days long.


Does Mercury spin counterclockwise?

yes, mercury does spin counter clockwise.


Why does the same side of mercury always face the sun?

This used to be believed, but we now realise it is not so. Mercury rotates 3 times for every 2 orbits of the Sun.


Does orbit Helios spin?

Yes, Orbit Helios does spin. I recommend him, because he spins very well :)


Does the earth spin on its axis only?

If by spin you mean "rotate daily" then yes. But you could refer to our "orbit" as a spin around the sun. But if you want to refer to "spin" as any oscillatory/periodic motion of the earth, then we spin around our central axis, we orbit around the sun, we precess the rotational axis around a precession axis, our obliquity oscillates periodically and our eccentricity oscillates around the foci of our elliptic orbit which is near the center of the sun. These characteristics of our orbit are known as the Milankovic cycles.

Does the Earth spin on its axis in the same or opposite direction as the moons orbit?

The direction of the Earth's spin and the direction of the Moon's orbit is the same - counterclockwise
