I'm Afraid to Ask This Internet to Name This New Moon
Good news! Three
One thing 2007 OR10 has going for it is that it's the third-largest confirmed dwarf planet , behind Pluto and Eris, which both have badass names. Other recognized dwarf planets include Makemake, Haumea, Ceres, and Sedna. A team of researchers first spotted 2007 OR10's moon in two separate Hubble archival images before following up with other telescopes, and their findings have been published in The Astrophysical Journal Letters .
"The discovery of satellites around all of the known large dwarf planets-except for Sedna-means that at the time these bodies formed billions of years ago, collisions must have been more frequent, and that's a constraint on the formation models," Csaba Kiss of the Konkoly Observatory in Budapest, the study's lead author, said in a statement. "If there were frequent collisions, then it was quite easy to form these satellites."
The most exciting part of this discovery is that it suggests all objects in the Kuiper Belt larger than 600 miles (1000 km) across probably harbor satellites. That information may help scientists better understand conditions in the early solar system, as this region contains objects that are roughly 4.6 billion years old .
Sure, all the
