A billion years ago, the Moon was in a tighter orbit, taking just 20 days to go

around us and make a month. A day on Earth back then was only 18 hours long. The Moon is still moving away -- about

1.6 inches (4 centimeters) a year. Meanwhile, Earth's rotation is slowing

down, lengthening our days. In the distant future, a day will be 960 hours long!

• Crust: Silicate

• Mantle: Silicate

Saturn

Pluto• Pluto actually isn’t a planet but rather a

dwarf planet!• We’ll talk about dwarf planets next

time!
