Mercury is a planet filled with sulfur near the blazing sun when the planets are counted in the solar system, Mercury comes first. After that comes the orbits of Venus, Earth, and Mars. These four planets in the solar system are in solid form, they are also called inner planets. According to Roman myths, Mercury is the messenger of the gods, the Roman form of the Greek god Hermes, the god of trade, travel, and pilgrimage. It got the name of the messenger deity because the planet travels very fast in the sky, completing one of its revolutions in about 88 days. There is a light atmosphere on Mercury which is mainly made up of atoms from the solar wind. Mercury is very hot due to which these atoms fly into space. This is unlike Earth and Venus whose environment is permanent, Mercury's atmosphere keeps on being new. The data obtained from the mariner suggests that there is some volcanic activity on Mercury but some more data is needed to prove it. Surprisingly there is evidence of aquatic ice in the craters of Mercury's the North Pole. Evidence of this was also found from radar and there is no satellite of Mercury.
