The Craggy, Small Mercury

Mercury

Mercury is one of the smallest rocky planet. There are four rocky planets in our solar system (Mercury, Venus, Earth, and Mars). Mercury is the nearest planet to the sun. But it is not the hottest planet, as it does not has any atmosphere to hold the heat energy. If it would have the atmosphere then the temperature could rise up to 800 degree Fahrenheit (699.82K). The shiny light-blue streaks across mercury's surface are the crater rays that are formed in impact when fresh, ground-up rock is strewn across the surface of the planet.

Formation

When gravity pulled the rippled gas and the dust together about 4.5 billion years ago to form a small rocky planet near the sun.

Layer

1) Solid Inner Core: The scientist reported that the size of the mercury's inner core and the Earth's inner core is about the same size. It is a solid metallic core that is said to have the 85% of the mercury's total mass.

2) Outer Molten Core: This outer molten core is also almost the same as the Earth's one. Scientists are researching whether mercury has a molten layer or not. But till now it is believed that it is present.

3) Mantle: It is a hard solid rocky part of the mercury beneath the crust. This mantle is made up of Silicate Rocks.

4) Crust: The mercury has a thick crust, the same size as the earth, and is almost made up of silicate rocks. It may have ice caps in the north poles and the south poles. It has billions and billions of creators like the earth's moon.

Moons

The mercury does not have any moon.

FACTS!!!!!
