13536 (1991 RA15) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1991 RA15 as potentially hazardous because its orbit does not bring it close to Earth.
1991 RA15 orbits the sun every 2,060 days (5.64 years), coming as close as 2.70 AU and reaching as far as 3.64 AU from the sun. 1991 RA15 is about 11.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.
The rotation of 1991 RA15 has been observed. It completes a rotation on its axis every 8.75 hours.
1991 RA15's orbit is 1.68 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.
1991 RA15's orbit is determined by observations dating back to April 28, 1984. It was last officially observed on June 9, 2023. The IAU Minor Planet Center records 2,702 observations used to determine its orbit.
