Q:

What solar system do we live in?

A:

Our solar system is referred to simply as the Solar System. That is its name because it is a heliocentric model in which all planets in the system revolve about the sun.

The sun is a G2 star that belongs to the Milky Way galaxy. It is only one of an estimated 100 billion stars in this galaxy. The sun's age is about 4.5 billion years.

Eight planets revolve around the sun. These are Earth, Mercury, Mars, Uranus, Venus, Neptune, Jupiter and Saturn. At one time, Pluto was the ninth planet, but as of August 2006, it is classified as a dwarf planet.
