Key Facts

Overview

80806 (2000 CM105) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2000 CM105 as potentially hazardous because its orbit does not bring it close to Earth.

2000 CM105 orbits the sun every 99,500 days (272.42 years), coming as close as 39.07 AU and reaching as far as 44.95 AU from the sun. Based on its brightness and the way it reflects light, 2000 CM105 is probably between 122.055 to 272.923 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Vermont.

No Close Approaches

2000 CM105's orbit is 38.10 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

2000 CM105's orbit is determined by observations dating back to Feb. 6, 2000. It was last officially observed on March 18, 2023. The IAU Minor Planet Center records 125 observations used to determine its orbit.

Accessibility and Exploration

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