Key Facts

Overview

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

Anitahill orbits the sun every 1,290 days (3.53 years), coming as close as 2.13 AU and reaching as far as 2.50 AU from the sun. Anitahill is about 3.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of Anitahill has been observed. It completes a rotation on its axis every 38.34 hours.

No Close Approaches

Anitahill's orbit is 1.13 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

Anitahill's orbit is determined by observations dating back to March 17, 1991. It was last officially observed on July 5, 2023. The IAU Minor Planet Center records 3,374 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
