Key Facts

Overview

Paeonia is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Paeonia as potentially hazardous because its orbit does not bring it close to Earth.

Paeonia orbits the sun every 2,020 days (5.53 years), coming as close as 2.44 AU and reaching as far as 3.80 AU from the sun. Paeonia is about 23.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of Paeonia has been observed. It completes a rotation on its axis every 8.00 hours.

Paeonia's spectral type C (Tholen) / None (SMASSII) indicates that it is likely to contain water, iron, nickel, cobalt, nitrogen, and ammonia.

No Close Approaches

Paeonia's orbit is 1.45 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.

Images and Observations

Paeonia's orbit is determined by observations dating back to Oct. 10, 1925. It was last officially observed on June 25, 2023. The IAU Minor Planet Center records 3,511 observations used to determine its orbit.
