137294 (1999 RE215) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1999 RE215 as potentially hazardous because its orbit does not bring it close to Earth.
1999 RE215 orbits the sun every 111,000 days (303.90 years), coming as close as 40.54 AU and reaching as far as 50.04 AU from the sun. Based on its brightness and the way it reflects light, 1999 RE215 is probably between 134.448 to 300.635 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Massachusetts.
1999 RE215's orbit is 39.50 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.
1999 RE215's orbit is determined by observations dating back to Sept. 7, 1999. It was last officially observed on Aug. 27, 2022. The IAU Minor Planet Center records 61 observations used to determine its orbit.
