The Solar System that the Earth is in contains the Sun, 8 planets and 5 known dwarf planets [1], and also an asteroid belt between Mars and Jupiter. There is a huge asteroid belt beyond Pluto called the Kuiper belt. The Solar System is part of the Milky Way Galaxy and orbits that galaxy in roughly 250 Million years.


The Solar System formed when a cloud of interstellar gas and dust condensed to form the sun, the planets and the other objects in the Solar System. The gas and dust included Supernova remnants, we know that because the oxygen, nitrogen, carbon, also all other heavy elements in the Earth and elsewhere formed during one or more supernova explosions.

The Solar System revolves around a medium-sized Star called the Sun, or Sol. Yes, EARTH around SUN. When Galileo said that the Pope didn't believe him. Astronomers have found planets orbiting other stars or suns in other Planetary systems. They are called Exoplanets. In 2010 over 500 exoplanets were known. [2] and more are continually discovered. Some may have life though scientists don’t know yet. Nobody knows how many planets there are in the Universe.
