15288 (1991 RN27) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1991 RN27 as potentially hazardous because its orbit does not bring it close to Earth.
1991 RN27 orbits the sun every 1,510 days (4.13 years), coming as close as 2.50 AU and reaching as far as 2.67 AU from the sun. 1991 RN27 is about 8.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of 1991 RN27 has been observed. It completes a rotation on its axis every 7.14 hours.
1991 RN27's orbit is 1.50 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.
1991 RN27's orbit is determined by observations dating back to Dec. 22, 1954. It was last officially observed on June 30, 2023. The IAU Minor Planet Center records 3,909 observations used to determine its orbit.
