astronomers led by Scott S. Sheppard of the Carnegie Institution for Science in Washington revealed the orbital details of the world, which they have nicknamed the Goblin. Dr. Sheppard and his colleagues first spotted the world, which for now carries the official designation of 2015 TG387 as part of a systematic search three years ago for new worlds in the outer system, including the hypothesized Planet Nine. But only with additional observations did they realize how far out TG387 really is"

PS. Já tinha lido sobre a origem das "mass extinctions" poderem ter origem na estrela "gémea" do sistema duplo de que o sol faria parte. Esta é outra hipótese. No Daily Star? ;)
