2015 RG301 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2015 RG301 as potentially hazardous because its orbit does not bring it close to Earth.
2015 RG301 orbits the sun every 145,000 days (396.99 years), coming as close as 52.05 AU and reaching as far as 56.03 AU from the sun. Based on its brightness and the way it reflects light, 2015 RG301 is probably between 60.333 to 134.909 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
2015 RG301's orbit is 51.10 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2015 RG301's orbit is determined by observations dating back to Sept. 5, 2015. It was last officially observed on Oct. 16, 2015. The IAU Minor Planet Center records 5 observations used to determine its orbit.
