Key Facts

Overview

122106 (2000 HC86) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2000 HC86 as potentially hazardous because its orbit does not bring it close to Earth.

2000 HC86 orbits the sun every 1,370 days (3.75 years), coming as close as 1.65 AU and reaching as far as 3.17 AU from the sun. Based on its brightness and the way it reflects light, 2000 HC86 is probably between 1.488 to 3.327 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

2000 HC86's orbit is 0.64 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

2000 HC86's orbit is determined by observations dating back to April 3, 2000. It was last officially observed on May 25, 2022. The IAU Minor Planet Center records 617 observations used to determine its orbit.

Accessibility and Exploration

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