14 Amazing Fun Facts About Dwarf Planets That Will Blow Your Mind!

1. Eris: The Massive Dwarf Planet

Move over, Pluto – there's a new heavyweight in town, flexing its celestial muscles and leaving astronomers star-struck: Eris is now the most massive dwarf planet in our solar system, boasting a weight that's a whopping 27% more than the former "ninth planet". Its slow-motion orbital dance lasts 559.07 Earth years and takes place in the icy-rocky outskirts called the scattered disc. Discovered in 2005 by a team led by Mike Brown at the Palomar Observatory, Eris was named after the Greek goddess of strife and discord – a fitting nod to the ruckus it caused when it snatched Pluto's planetary crown, only to be categorized as a mere dwarf planet itself.
