Washington, DC\u2014<\/strong>Carnegie\u2019s Scott Sheppard and his colleagues\u2014Northern Arizona University\u2019s Chad Trujillo<\/strong>, and the University of Hawaii\u2019s David Tholen \u2014 are once again redefining our Solar System\u2019s edge. They discovered a new extremely distant object far beyond Pluto with an orbit that supports the presence of an even-farther-out, Super-Earth or larger Planet X.<\/p>\n The newly found object, called 2015 TG387, was announced Tuesday by the International Astronomical Union\u2019s Minor Planet Center. A paper with the full details of the discovery has also been submitted to The Astronomical Journal<\/em>.<\/p>\n 2015 TG387 was discovered about 80 astronomical units (AU) from the Sun, a measurement defined as the distance between the Earth and Sun. For context, Pluto is around 34 AU, so 2015 TG387 is about two and a half times further away from the Sun than Pluto is right now.<\/p>\n . . .<\/p>\n
