115069 (2003 RE21) is a mid-sized asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 2003 RE21 as potentially hazardous because its orbit does not bring it close to Earth.
2003 RE21 orbits the sun every 2,750 days (7.53 years), coming as close as 3.53 AU and reaching as far as 4.15 AU from the sun. 2003 RE21 is about 8.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
2003 RE21's orbit is 2.53 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.
2003 RE21's orbit is determined by observations dating back to Nov. 7, 1996. It was last officially observed on June 8, 2023. The IAU Minor Planet Center records 844 observations used to determine its orbit.
