18300 (1979 PA) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1979 PA as potentially hazardous because its orbit does not bring it close to Earth.
1979 PA orbits the sun every 1,490 days (4.08 years), coming as close as 1.88 AU and reaching as far as 3.24 AU from the sun. 1979 PA is about 9.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of 1979 PA has been observed. It completes a rotation on its axis every 5.36 hours.
1979 PA's orbit is 0.90 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.
1979 PA's orbit is determined by observations dating back to Aug. 14, 1979. It was last officially observed on May 25, 2023. The IAU Minor Planet Center records 2,379 observations used to determine its orbit.
