Key Facts


2010 OM101 is a mid-sized asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2010 OM101 as potentially hazardous because its orbit does not bring it close to Earth.

2010 OM101 orbits the sun every 48,900 days (133.88 years), coming as close as 2.15 AU and reaching as far as 50.19 AU from the sun. Its orbit is highly elliptical. 2010 OM101 is about 3.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

No Close Approaches

2010 OM101's orbit is 1.23 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

2010 OM101's orbit is determined by observations dating back to July 28, 2010. It was last officially observed on Nov. 6, 2010. The IAU Minor Planet Center records 43 observations used to determine its orbit.

Accessibility and Exploration

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