Frosty the Planet: Renaming Ultima Thule, a snowman-shaped planetesimal

On New Year’s Day, NASA’s New Horizons spacecraft took a photo of two icy spherical objects that joined together over 4.6 billion years ago. Scientists believe this 21-mile-long snowman-shaped planetesimal named Ultima Thule can give us clues on how Earth and other planets in our solar system were formed.


 PopNamers, let’s get this snowball rolling and rename Ultima Thule.
