Key Facts

Overview

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

Annapavlova orbits the sun every 1,500 days (4.11 years), coming as close as 2.28 AU and reaching as far as 2.84 AU from the sun. Annapavlova is about 9.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Annapavlova has been observed. It completes a rotation on its axis every 44.63 hours.

No Close Approaches

Annapavlova's orbit is 1.33 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

Annapavlova's orbit is determined by observations dating back to April 1, 1976. It was last officially observed on July 5, 2023. The IAU Minor Planet Center records 2,757 observations used to determine its orbit.

Accessibility and Exploration

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