The Goblin - Dwarf Planet Candidate

The video introduces 2015 TG387, nicknamed the Goblin, a trans-Neptunian object discovered in October 2015 near Halloween. It was found by astronomers Chad Trujillo, David Tholen, and Scott Shepherd using the Subaru telescope. The Goblin has an elongated orbit, never coming closer than 80 AU to the Sun and reaching as far as 2300 AU. Its orbit, along with Sedna's, suggests the influence of a hypothetical planet. The video also discusses the existence of many small dwarf planets beyond Pluto, highlighting the potential for future discoveries with advancing technology.
