Mass of Dwarf Planet Eris 27% Greater than Pluto

Posted by Zonk on from the she-wants-a-bite-of-the-apple dept.

jcgam69 writes "When it was discovered in 2005, some thought Eris should be considered the 10th planet of our solar system. Everyone still considered Pluto a planet then. At first, Eris was thought to be slightly larger. Now — with the help of Eris' moon — Eris is known to be 27% more massive than Pluto. If Pluto had remained a planet to the entire community of astronomers, surely Eris would be considered the 10th planet."

    Can you point me at a round asteroid in the belt?

    OK, look up. A little more to your left. A bit more. OK, just a little bit more. Nope, that's too far. Just a hair back to your right. There! See it?
