Key Facts

Overview

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

Omarkhayyam orbits the sun every 2,380 days (6.52 years), coming as close as 3.22 AU and reaching as far as 3.77 AU from the sun. Omarkhayyam is about 30.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of Omarkhayyam has been observed. It completes a rotation on its axis every 11.92 days.

No Close Approaches

Omarkhayyam's orbit is 2.23 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

Omarkhayyam's orbit is determined by observations dating back to Nov. 12, 1974. It was last officially observed on Jan. 27, 2020. The IAU Minor Planet Center records 2,521 observations used to determine its orbit.

Accessibility and Exploration

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