WHAT IS THE PLANET MERCURY??
Mercury is a planet that is part of the Solar system. It is also the closest planet to the Sun. Mercury takes 59 days to make a full rotation but only 88 days to orbit the Sun.And it is also the smallest planet out of the eight other planets in the solar system.Because Mercury is so close to the sun it has the smallest orbit of all planets. Did you know that Mercury was actually named after a roman version of the greek god Hermes,he was one of the messengers for the other gods.
How big is Mercury?
The diameter of Mercury is 4879km,and the mass of Mercury is 0.33 x 10 24kg.With barely 20 % of Earth's mass,Mercury is so small that its gravity is too weak to hold on to a permanent atmosphere.The outside crust and mantle are largely rock,but the core is 75% of its diameter is solid iron. Mercury is also the smallest planet in both mass and diameter the solar system.it is about eighteen times less humungous than Earth.Mercury has a diameter of about 3,032 miles (3879km).Here I'll give you an example if the Earth was a big basketball then Mercury would only be a cricket ball.If you were wondering ''why is Mercury so heavy for it's size"?well the reason why Mercury is heavy for its size is because of the density there is in Mercury.
What does mercury's atmosphere consists of?
what is the atmosphere of mercury actually made of well it is made of helium,sodium,calcium,potassium and hydrogen and water vapour.scientist think mercury is mainly made of molten iron and most of this iron is mainly in the larger core.scientists believe that mercury has a thin rocky crust with a large metalic core.mercury is covered in craters and has ice for its poles.
