Key Facts

Overview

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

Ogarev orbits the sun every 1,380 days (3.78 years), coming as close as 1.99 AU and reaching as far as 2.86 AU from the sun. Ogarev 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 Ogarev has been observed. It completes a rotation on its axis every 32.99 hours.

No Close Approaches

Ogarev's orbit is 0.99 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

Ogarev's orbit is determined by observations dating back to Oct. 9, 1953. It was last officially observed on April 17, 2023. The IAU Minor Planet Center records 3,155 observations used to determine its orbit.

Accessibility and Exploration

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