Dobrovolsky

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the San Francisco Bay (7.92 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Dobrovolsky orbits the sun every 1,200 days (3.29 years), coming as close as 1.80 AU and reaching as far as 2.63 AU from the sun. Dobrovolsky is about 7.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Dobrovolsky has been observed. It completes a rotation on its axis every 4.81 hours.

No Close Approaches

Dobrovolsky's orbit is 0.78 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

Dobrovolsky's orbit is determined by observations dating back to Sept. 24, 1943. It was last officially observed on March 5, 2023. The IAU Minor Planet Center records 4,323 observations used to determine its orbit.
