A team of astronomers have discovered a new dwarf planet in our solar system. Dubbed 2015 RR245, it is 120 times farther from the Sun than the Earth at its farthest orbital point. "The icy worlds beyond Neptune trace how the giant planets formed and then moved out from the Sun. They let us piece together the history of our Solar System," says Dr. Michele Bannister of the University of Victoria in British Columbia, one of the researchers behind the finding. The super-precision telescope on Maunakea, Hawaii, deemed one of the best optical observing locations on Earth, found 2015 RR245 as part of the ongoing Outer Solar System Origins Survey (OSSOS), which is being conducted by a team of some 50 astronomers from institutes and universities throughout the world. They have discovered over 500 objects beyond Neptune's orbit so far, but 2015 RR245 is their first dwarf planet. The dwarf was first spotted back in February as a "dot of light moving so slowly that it had to be at least twice as
