An important unit in the solar system is the astronomical unit, or au, that refers to the average distance between and the sun of 93 million miles. except for the moon hyperion that orbits saturn, all known moons in the solar system are locked. most moons have prograde orbits about their planets, meaning that they orbit in the same direction as their planets many comets, meteorites, and other large bodies called dwarf planets can be found in the belt.

describe the processes occurring in a nebula and explain why rocky planets are formed closer to the center of the solar system.

1.Earth

2.tidally

3.spin

4.Kuiper

5.A solar nebula forms when the gas and dust are pulled together in a spinning disk. Particles began to clump together due to gravity, and larger chunks of material exert more gravity on nearby dust and gas. These chunks of material grew faster and formed planets or moons. Denser elements such as iron settled closer to the center of the solar nebula.
