1. Formation
Since the time of
Copernicus, Kepler, and Galileo, we have learned a lot more about our solar system.

Astronomers have discovered two more planets (Uranus and Neptune), five dwarf planets (Ceres, Pluto, Makemake, Haumea, and Eris), more than 150 moons, and many, many asteroids, comets and other small objects.

Our solar system including the sun, planets, and many asteroids all are formed around 4,5 thousand million years ago.

The solar system was formed due to the gravitational collapse of a giant cloud and dust in space. This made a disturbance in the cloud that results create clumps of gases due to gravity. Astronomers estimate that this happened because of the explosion with a supernova star.
Scientists believe that this interstellar cloud was so massive and started the contraction of most molecules in the center.

So, the major part of this cloud and dust at the center formed the Sun.

Other clumps of clouds and dust formed the planets and smaller bodies in the solar system, in which the majority of mass formed the planet Jupiter.
