Scientists have discovered a new dwarf planet at the edge of our solar system. Known for now as 2014 UZ224, the newly found planet is 330 miles wide, 8.5 billion miles from the sun, and has a year equivalent to 1,100 Earth years (that’s how long it takes the tiny planet to orbit the Sun)!

The discovery of UZ224 was possible thanks to the Dark Energy Camera in the Chilean Andes. University of Michigan astronomer David Gerdes, who helped develop the camera, led a group of undergraduate students to look for objects moving about in the solar system.
Objects like stars don’t appear to move positions from our vantage point on Earth, because they’re so far away. But planets or asteroids will show up in slightly different positions in pictures taken over multiple nights. In the discovery of 2014 UZ224, however, the pictures of the galaxy map weren’t from a straight succession of nights.
