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 mercury demonstrate gravitational locking?

No. Mercury was once believed to be tidally locked to the sun, meaning it rotates once for every orbit so that the same side always faces the sun. Closer observation found that Mercury is not tidally locked.


What is the distance in miles from earth to mercury in scientific notation?

The distance between earth and mercury depends on whether mercury is on the same side of the sun or the opposite side!


How is mercury's surface different from earth's?

they both are on the same axis on the side of the sun.


What is the hot side of mercury made out of?

It is made of of rock. The same type that the cold side is. The hot side of Mercury does not have any special properties. It's only hot because it faces the sun.


Is mercury really hot and really cold?

The side of Mercury that faces the sun is extremely heated, however the side of Mercury that faces away from the sun is extremely cold.


How many orbits around the Sun must Mercury make before the same face is lit by the Sun?

Mercury takes about 59 Earth days to complete one orbit around the Sun. It also takes about 88 Earth days for Mercury to rotate on its axis, which is slightly more than one Mercury year. Therefore, Mercury would have to go through more than one orbit (at least 1.5 orbits) for the same face to be fully illuminated by the Sun again.


How does the planet Mercury feel?

Hot. Mercury is very close to the Sun; the sun-side temperatures on Mercury will melt most metals.


Why is mercury hot on one side and cold on the other side?

This is not true. For many years, it was thought that Mercury was in synchronous tidal lock with the Sun: that is, its orbital and rotational periods were the same so that the same side faced the Sun (much like we only see one side of the Moon). However, radar observations in 1965 showed this to be false: the planet spins three times for every two revolutions around the Sun.


What is the average distance of mercury away from the earth?

Both Mercury and Earth are orbiting the Sun. At some time they are on the same side of the sun and at others they are on opposite sides of the Sun. Thus the concept of an average distance between them is almost meaningless as it is constantly changing.The average distance of Mercury from the Sun is 57,909,100 km.The average distance of Earth from the Sun is 149,597,887 km.


Is water present on mercury?

don't think so. no its to close to the sun.


How hot does it get the side of mercury closets to the sun?

At the equator, the surface temperature on Mercury (facing the sun) can reach 700K (430'C).


How hot does it get on the side of mercury close to the sun?

super hot
