Initially designated as 2002 LM 60, Quarrer is roughly half the size of Pluto and has a nearly circular orbit around the sun, taking 285 Earth years to complete. Its surface is composed of crystalline ice and ammonia hydrate. Quarrer has a moon named Weywot, discovered in 2006. The video encourages viewers to explore more trans-Neptunian objects.
