The body formation of the Moon

The Moon was formed by a protoplanet the size of Mars crashing into the Earth. After the impact, gas and dust surrounded the Earth. The Earth gathered some of the debris and it got bigger. Most of the debris gathered together to form the Moon. The Earths gravitational pull pulled the Moon so that the Moon orbits the Earth.

Why Pluto is not a planet

In order for a body to be a planet It has to meet three requirements, 1. it has to orbit a star. 2. it has to have a gravitational pull to control the bodies in its neighborhood. 3. It has to be spherical. Pluto, a dwarf planet is not considered a planet because, it does not have a gravitational pull to control the bodies in the planets neighborhood. Although, it meets the other requirements, it is still not a planet because of this requirement. Another example of a body that is not a planet, is the Moon. The moon is not a planet, because it does not have a gravitational pull to control the bodies in the neighborhood. Also the Moon, does not orbit a star, which makes the Moon, a moon, which means the Moon is not a planet.
