Alicemanning

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the city of Philadelphia (17.60 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Alicemanning orbits the sun every 2,060 days (5.64 years), coming as close as 2.60 AU and reaching as far as 3.73 AU from the sun. Alicemanning is about 17.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.

The rotation of Alicemanning has been observed. It completes a rotation on its axis every 15.89 hours.

No Close Approaches

Alicemanning's orbit is 1.58 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

Alicemanning's orbit is determined by observations dating back to Sept. 27, 1954. It was last officially observed on Feb. 19, 2023. The IAU Minor Planet Center records 3,586 observations used to determine its orbit.
