Solar system - The Universe

The solar system is a collection of celestial objects that orbit around the sun, including the planets and their moons, as well as smaller objects like asteroids and comets. The sun is the center of the solar system and is located in the Milky Way galaxy, which is a vast collection of stars, planets, and other objects that are held together by gravity. The solar system is just a tiny part of the universe, which is made up of all the galaxies and everything that exists in them. Scientists believe that the universe was created about 14 billion years ago and is still expanding.
