Key Facts

Overview

Oomine is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified Oomine as potentially hazardous because its orbit does not bring it close to Earth.

Oomine orbits the sun every 1,180 days (3.23 years), coming as close as 1.66 AU and reaching as far as 2.71 AU from the sun. Based on its brightness and the way it reflects light, Oomine is probably between 3.123 to 6.983 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

The rotation of Oomine has been observed. It completes a rotation on its axis every 2.62 hours.

No Close Approaches

Oomine's orbit is 0.67 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

Oomine's orbit is determined by observations dating back to Sept. 20, 1974. It was last officially observed on Aug. 31, 2022. The IAU Minor Planet Center records 2,061 observations used to determine its orbit.

Accessibility and Exploration

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