Key Facts

Overview

Abastumani is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Abastumani as potentially hazardous because its orbit does not bring it close to Earth.

Abastumani orbits the sun every 2,320 days (6.35 years), coming as close as 3.31 AU and reaching as far as 3.56 AU from the sun. Abastumani is about 95.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.

The rotation of Abastumani has been observed. It completes a rotation on its axis every 26.49 hours.

Abastumani's spectral type P (Tholen) / None (SMASSII) indicates that it is likely to contain .

No Close Approaches

Abastumani's orbit is 2.32 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

Abastumani's orbit is determined by observations dating back to Oct. 26, 1929. It was last officially observed on July 2, 2023. The IAU Minor Planet Center records 4,952 observations used to determine its orbit.

Accessibility and Exploration

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