Differences between Neptune and Earth

Differences between Neptune and Earth
By Abby

     Earth and Neptune are very different. These are some ways that they are different. Neptune's atmosphere is made of hydrogen, helium, and methane, while Earth's atmosphere is made of oxygen and nitrogen. People live on earth and no one has been to Neptune. Earth is the third planet from the sun and Neptune is the eighth planet. These are some of the differences.
