'Fossil' Discovered Beyond Pluto Implies 'Something Dramatic' Happened 400M Years Ago
"The distant reaches of the Solar System are still mysterious," writes ScienceAlert. "Not much sunlight pierces these regions, and there are strong hints that undiscovered objects lurk there. The objects that astronomers have discovered in these dim reaches are primordial, and their orbits suggest t...
"And now thanks to the giant 8.2-meter Subaru telescope at Hawaii's Mauna Kea Observatory, astronomers have discovered "a massive new solar system body located beyond the orbit of Pluto," reports Space.com. The weird elongated orbit of the object suggests that if "Planet Nine" exists, it is much further from the sun than thought, or it has been ejected from our planetary system altogether. However, the team behind the discovery, made using Subaru Telescope as part of the Formation of the Outer Solar System: An Icy Legacy (FOSSIL) survey, thinks that all four sednoids were on similar orbits around 4.2 billion years ago.
