Key Facts

Overview

613939 (2008 CH116) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2008 CH116 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2008 CH116 orbits the sun every 197 days (0.54 years), coming as close as 0.27 AU and reaching as far as 1.05 AU from the sun. 2008 CH116 is about 0.3 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to a football field.

No Close Approaches

2008 CH116's orbit is 0.23 AU from Earth's orbit at its closest point. This means that there is a 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

2008 CH116's orbit is determined by observations dating back to Feb. 9, 2008. It was last officially observed on Feb. 12, 2023. The IAU Minor Planet Center records 148 observations used to determine its orbit.

Accessibility and Exploration

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