You can see a drawing of the Milky Way below which shows what our Galaxy

Solar System

A star system is a group of planets, meteors, or other objects that orbit a large star. While there are many star systems, including at least 200 billion other stars in our galaxy, there is only one solar system. That''s because our sun is known by its Latin name, Sol.

How Many Suns Are In Our Solar System?

So, how many suns are in our solar system? There are an estimated 100 billion stars in our Milky Way galaxy alone making up about 100 billion suns. Our solar system is just one small part of this vast galaxy, so the answer to how many suns are in our solar system is a tiny fraction of the total number of suns in the Milky Way.

Moons of Our Solar System

How Many Moons Are in Our Solar System? Naturally-formed bodies that orbit planets are called moons, or planetary satellites. The best-known planetary satellite is, of course, Earth''s Moon.

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers
