What is the solar system? It is our Sun and everything that travels around it.

Our solar system is elliptical in shape. That means it is shaped like an egg.

The Sun is in the center of the solar system. Our solar system is always

in motion. Eight known planets and their moons, along with cometsasteroids,

and otherspace objects orbit the Sun. The Sun is the biggest object in our solar

system. It contains more than 99% of the solar system's massAstronomers

think the solar system is more than 4 billion years old.

 

Astronomers are now finding new objects far, far from the Sun which

they call dwarf planets. Pluto, which was once called a planet, is

now called a dwarf planet.
