**What have we learned through space travel?**
Through space travel we have learned about so many different things like planets and what they are made of.
 * Venus- has a core of metal, a mantle of liquid rock, and has an outer crust of solid rock
 * Mercury- is a small rocky planet much like our moon. It has most likely changed very little from when it was first formed. Mercury has only been mapped 45%.
 * Uranus and Neptune- are manly composed of hydrogen and helium but have much more methane and ices.
 * Jupiter and Saturn- are manly composed of hydrogen, helium and nitrogen. They are sometimes called the "gas planets"
 * Saturn- is made up of 75% hydrogen and 25% helium. Saturn's rings are manly made up of water ice but may also include rocky particles coated with ice. Saturn is very light if you put it in water it would float.
 * Jupiter- is 90% hydrogen and 10% helium. Jupiter has a swirling storm that has lasted for hundreds of years
