The essential about Earth
Earth is probably the jewel of the solar system. Endowed with incredible diversity, it is remarkable in many ways. Earth is the densest planet in the solar system. Some experts consider it a double planet. Earth is indeed the only rocky planet in the solar system to have a massive satellite. Earth and the Moon form an atypical pair because the most living celestial object of the solar system is next to one of the deadest satellite of the solar system.
Earth’s orbit around the sun is the most circular of the eight planets, and its powerful magnetic field shields Earth from the rage of its star. It may be the marriage of all these peculiarities that has allowed life to emerge on Earth. You may identify our planet with its fertile soil and green vegetation, but it is the liquid water that defines Earth first and foremost. Water covers three quarters of the Earth’s surface, so it’s called the blue planet.
