Key Facts

Overview

2012 JH67 is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2012 JH67 as potentially hazardous because its orbit does not bring it close to Earth.

2012 JH67 orbits the sun every 121,000 days (331.28 years), coming as close as 34.94 AU and reaching as far as 60.96 AU from the sun. Based on its brightness and the way it reflects light, 2012 JH67 is probably between 211.132 to 472.106 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of West Virginia.

No Close Approaches

2012 JH67's orbit is 34.00 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

2012 JH67's orbit is determined by observations dating back to April 19, 2010. It was last officially observed on June 14, 2020. The IAU Minor Planet Center records 80 observations used to determine its orbit.

Accessibility and Exploration

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