Key Facts

Overview

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

Aho orbits the sun every 1,980 days (5.42 years), coming as close as 2.95 AU and reaching as far as 3.22 AU from the sun. Aho is about 20.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of Aho has been observed. It completes a rotation on its axis every 7.88 hours.

No Close Approaches

Aho's orbit is 1.93 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

Aho's orbit is determined by observations dating back to April 17, 1950. It was last officially observed on Dec. 1, 2022. The IAU Minor Planet Center records 3,827 observations used to determine its orbit.
