| The Mercury |
|
Mercury is the innermost planet in the Solar System which is why its temperature is extremely high and the atmosphere is almost non-existent. Therefore, Mercury is within close proximity to Earth as well. This is why it can be seen in the night sky and is referred to as the morning star because it can |
 |
be seen before Sunrise. Sometimes, it is visible after Sunset as well.
Because of its closeness to the Sun, the composition of this Solar System planet is different when compared to the rest of the planets. Iron is a major part of this composition which basically makes the planet an iron ball but with a fragile silicate crust. |

Mercury is the small planet which is why it is very cool and the core is solid. Initially, when the iron cooled, it started to contract and shrink simultaneously, which caused wrinkles to appear. Today, these wrinkles are called Lobate Scarpes.
Similar to the Earth’s Moon, there are a number of craters on the surface of this Solar System planet. This is because Mercury came in contact with a number of comets and asteroids during the initial years of the formation of the Solar System. There is neither any volcanic activity nor a stable atmosphere which is why these scars will never heal.
Mercury doesn’t have any satellites. It takes 87.969 Earth days for Mercury to complete an orbit.
