• Mercury is the closest planet to the sun
• Mercury orbits the sun in about 88 Earth days but takes 58 Earth days to rotate once.
• On this planet a year takes a (Mercury) day and a half!

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!
Mars
• Crust: Silicate
• Mantle: Silicate
• Core: Iron Sulfide
Dinosaurs on Jupiter!
Saturn
Pluto• Pluto actually isn’t a planet but rather a
dwarf planet!• We’ll talk about dwarf planets next
time!
