Pluto: a dwarf planet (was once the 9th planet)

Venus: Hottest planet

Earth: 5th biggest planet (365 days to revolve around the Sun)

- Mainly covered by water

- Has only 1 moon

Moon: revolves around the Earth and Sun (28 days)

- Moon light we see is light from the Sun

Asteroids: Rocky bodies left over from the formation of planets (does not have even gravity to pull them into a ball)

Comets: balls of rock and ice, grow tails as they approach the sun (gets more visible as they approach).

Many solar systems form a galaxy (we live in the Milky way galaxy).
