8512 (1991 PC11) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1991 PC11 as potentially hazardous because its orbit does not bring it close to Earth.
1991 PC11 orbits the sun every 1,590 days (4.35 years), coming as close as 2.23 AU and reaching as far as 3.10 AU from the sun. 1991 PC11 is about 15.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Baltimore.
The rotation of 1991 PC11 has been observed. It completes a rotation on its axis every 99.01 hours.
1991 PC11's orbit is 1.25 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 PC11's orbit is determined by observations dating back to March 5, 1989. It was last officially observed on April 15, 2023. The IAU Minor Planet Center records 4,041 observations used to determine its orbit.
