The Solar System

The Solar System is the gravitationally -bound system comprising the Sun and the objects that orbit it, either directly or indirectly.

Of those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies.

And those that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury.


We know that the Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. (see – How was the Earth born)

Our Solar System consists of (mass distribution within Solar System given in bracket) –

  • Sun: 99.85%
  • Planets: 0.135%
  • Comets: 0.01%
  • Satellites: 0.00005%
  • Minor Planets: 0.0000002%
