@astrofacts.tiktok: The Forgotten '10th Planet' of the Solar System? 🪐✨ The discovery of Eris in 2005 changed the way scientists classify planets. Since Eris is similar in size to Pluto, astronomers introduced a new definition of a planet, and both Pluto and Eris were reclassified as dwarf planets. This decision permanently changed the list of planets in our Solar System. #Pluto #Eris #SpaceFacts #Astronomy #ScienceFacts
