These Are Some of the Solar System’s Biggest Surprises
The universe is full of surprises, but two discoveries in the outer solar system are dominating astronomy news this week.
First, astronomers reported yesterday that they have found a distant, tiny world – a small, icy body that lives in the darkness far beyond the orbit of Neptune. Called 2012 VP113, the world’s existence challenges theories describing the infant solar system, and flames speculation that a large planet hides on the fringes of detection. 2012 VP113 and its sibling Sedna are now the two farthest-flung, roundish objects we’ve spied whose gravitational allegiance lies with the sun.
