Io: The Space Pizza

By: Emma Sharp

Io's interesting facts!

Io was first discovered by Galileo Galilei,or a Galilean moon. It is one of Jupiter's main moons. It is also one of the four Galilean moons. It is considered the space pizza because of all of the active volcanoes on it. No, it's not made of actual pizza. :-(. It was discovered on January 8, 1610. It is 4.5 BILLION years old!!! Io has a radius of 1,131.7 miles around. It is only slightly bigger than the earth's moon. It's atmosphere is made mostly of sulfur dioxide. Let's not go live there, okay? ;-p
