What is solar system

The Solar System is the Sun and all the objects that orbit around it. The Sun is orbited by planets, asteroids, comets and other things. The Solar System is about 4.6 billion years old. The other objects are pulled into orbit around the Sun. All these things together are called a system. The Latin word for the Sun is Sol, so we call this system the Solar System. ... He showed that it was very likely that all the planets moved around the Sun. This time even more people thought Galileo may be right and that the Earth really did move around the Sun. Hence, the solar system consists of the sun and everything that orbits, or travels around, the sun. This includes the eight planets and their moons, dwarf planets, and countless asteroids, comets, and other small, icy objects. However, even with all these things, most of the solar system is empty space.
