Wow! A new trans-Neptunian object maybe twice the size of Pluto! That would make it the largest object found in the Solar System since Neptune in 1846!

Things smaller than Mars but at least as big as Pluto:

  1. I love the Gormenghast Trilogy and have read it at least 10 times since first reading it when I was 15. I also recommend the China Mieville books (obviously).
