Milky way
The Milky Way is a huge collection of several hundred billion stars, dust, and gas. It is a spiral galaxy that is about 13.6 billion years old. The Milky Way is the galaxy that includes our Solar System. The Solar System is located at a radius of about 27,000 light-years from the galaxy’s center. The galaxy is rotating, and it takes us about 240 million years to complete one circle around its middle.
