From/de SolarSystemQuick 

  • It is thought that the Moon formed 4.5 billion years ago from vaporized rock after the Earth collided with a planet size object.
  • The Moon is around a quarter the size of Earth but has a mass 81 times less than our planet.
  • The Moon orbits the Earth at an average distance of 239,000 miles (384,000 km).
  • The Moon spins on its own axis every 27.3 days, it also takes the same time to complete one orbit of Earth, as a result we only ever see one side of its surface.
  • The Moon is moving 3.8 cm further away from the Earth every year.
  • Gravity on the Moon is one sixth of that on Earth.
  • Despite the Moon’s weak gravity it is strong enough to produce tides on Earth.
  • The largest crater on the Moon is 1,550 miles (2,500 km) in diameter.
  • Ice water from comets that hit the Moon has been detected at both its poles and may be present in other areas.
  • Neil Armstrong became the first man to step on the Moon on July 20, 1969. Read More

Double planet system


In astronomy, double planet and binary planet are informal terms used to describe a binary system of two astronomical objects that each satisfy thedefinition of planet and that are near enough to each other to have a significant gravitational effect on each other compared with the effect of the star(s) they orbit. As of 2010, there are no officially classified double planets in our Solar system. One unofficial definition is that the objects orbit a common center of gravity, the barycenter, that is above both their surfaces.[citation needed] Read More
