Ambartsumian

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the San Francisco Bay (8.01 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Ambartsumian orbits the sun every 1,210 days (3.31 years), coming as close as 1.86 AU and reaching as far as 2.59 AU from the sun. Ambartsumian is about 8.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Ambartsumian has been observed. It completes a rotation on its axis every 92.15 hours.

No Close Approaches

Ambartsumian's orbit is 0.85 AU from Earth's orbit at its closest point. This means that there is a very 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

Ambartsumian's orbit is determined by observations dating back to April 1, 1932. It was last officially observed on Feb. 3, 2023. The IAU Minor Planet Center records 4,154 observations used to determine its orbit.
