Pluto, our dear friend, you left and now you are back, what can you tell us about your self?


Pluto was named after the long eared dog from the disney films? Absolutely not, it was named after the Roman God of the Underworld, because Pluto is crazy dark because it is sooooo far from the sun.

The radius of Pluto is 1151 km, which is about 1/5 (20%) the size of Earth. This makes Pluto a really small planet, in fact the smallest. The mass of Pluto is even smaller, about 1/500th of Earths mass.
