5818 (1989 RC1) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1989 RC1 as potentially hazardous because its orbit does not bring it close to Earth.
1989 RC1 orbits the sun every 1,340 days (3.67 years), coming as close as 1.72 AU and reaching as far as 3.02 AU from the sun. 1989 RC1 is about 9.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
1989 RC1's orbit is 0.79 AU from Earth's orbit at its closest point. This means that there is a very 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.
1989 RC1's orbit is determined by observations dating back to Dec. 21, 1982. It was last officially observed on March 31, 2023. The IAU Minor Planet Center records 3,910 observations used to determine its orbit.
