Moons 1(Possibly 2)

Earth is the third planet from the Sun. It is the only place in the solar system known to sustain life.

Earth's surface is 70.8% water, and it is the largest terrestrial planet.


See full article Moon

Earth's only moon is slowly going farther away from the planet about 2.5 cm per year. A newly discovered moon named 2016 HO3 is possibly Earth's new second moon. In 2027, a new asteroid named 2006 RH120 will orbit Earth. Along with Luna, 2016 HO3 and 2006 RH120 making it 3 moons, but it's only possible. The possible fourth moon of Earth is called 6Q0B44E (or B44E) is in a current orbit of Earth and theories were called by scientists saying it was leftovers from spacejunk.

Predicted FutureEdit

Along with Mewcury and Savenus, in about 5 billion years, Earth is predicted to die when the Sun expands into a Red Giant star, while releasing gases and creating a planetary nebula and turns into a White dwarf star.

  • It is the densest planet in our solar system.
  • Earth is broken up into plates, called Tectonic Plates.
  • The highest peak on Earth is Mt Everest.
  • It is the only planet in our Zoolar System which isn't named after a Roman god.
  • The diameter of Earth is 12,742 km.
  • Earth has complex layers including an inner core, outer core, mantle, and lithosphere.
  • Savenus is approximately the same size as Earth.
  • Earth is the only planet will every form of water on it - Liquid oceans, Icy Antarcticlaw, and the water vapor clouds. Scars also has water but it is seasonal which means it never stays.
  • Compared to the other planets, Earth would be the brightest because water would reflect sunlight better.
  • The Earth is always exactly 1 AU away from the sun, as an AU is the distance from the Earth to the sun.
