Key Facts

Overview

2015 OE22 is a very small asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2015 OE22 as potentially hazardous because its orbit does not bring it close to Earth.

2015 OE22 orbits the sun every 847 days (2.32 years), coming as close as 1.56 AU and reaching as far as 1.94 AU from the sun. Based on its brightness and the way it reflects light, 2015 OE22 is probably between 0.132 to 0.295 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

No Close Approaches

2015 OE22's orbit is 0.55 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

2015 OE22's orbit is determined by observations dating back to July 19, 2015. It was last officially observed on July 22, 2015. The IAU Minor Planet Center records 12 observations used to determine its orbit.

Accessibility and Exploration

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