86177 (1999 RY215) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1999 RY215 as potentially hazardous because its orbit does not bring it close to Earth.
1999 RY215 orbits the sun every 113,000 days (309.38 years), coming as close as 34.53 AU and reaching as far as 56.93 AU from the sun. Based on its brightness and the way it reflects light, 1999 RY215 is probably between 106.305 to 237.706 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Connecticut.
1999 RY215's orbit is 33.60 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 RY215's orbit is determined by observations dating back to Sept. 8, 1999. It was last officially observed on Oct. 6, 2021. The IAU Minor Planet Center records 140 observations used to determine its orbit.
