It's an asteroid! No, it's the new smallest dwarf planet in our solar system

From CNN:

"(CNN) - A large asteroid could be reclassified as a dwarf planet -- which could make it the smallest in the solar system -- after new research revealed it's shape, astronomers said on Monday.

Nestled in the asteroid belt between Mars and Jupiter is an object that may have been overlooked. They believe the asteroid Hygiea should actually be classified as a dwarf planet."

Here's another article from Ars Technica:

"Collision liquified the 4th-largest astroid, turning it into a dwarf planet"
