Discovered: The Most-Distant Solar System Object Ever Observed
A team of astronomers has discovered the most-distant body ever observed in our Solar System. It is the first known Solar System object that has been detected at a distance that is more than 100 times farther than Earth is from the Sun. It was announced Monday by the International Astronomical Union's Minor Planet Center. Carnegie's Scott S. Sheppard, the University of Hawaii's David Tholen, and Northern Arizona University's Chad Trujillo made the discovery.
