Used to be nine planets but recently Pluto has been re-classified as a dwarf planet so there are now only 8 planets. All of these planets move in a big path around the blazing sun. Did you know that the sun is so big that 1,000,000 of our Planet Earths could fit inside it? Whoa! That is almost too big to imagine!

The planets are divided into two main groups, inner and outer, based on how close they are to the sun. The inner planets are closer to the sun, while the outer planets are further from the sun.

Do you think Earth is an inner or outer planet?
