Key Facts


501546 (2014 JJ80) is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2014 JJ80 as potentially hazardous because its orbit does not bring it close to Earth.

2014 JJ80 orbits the sun every 105,000 days (287.47 years), coming as close as 31.28 AU and reaching as far as 55.64 AU from the sun. Based on its brightness and the way it reflects light, 2014 JJ80 is probably between 186.447 to 416.908 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.

No Close Approaches

2014 JJ80's orbit is 30.30 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

2014 JJ80's orbit is determined by observations dating back to July 20, 2010. It was last officially observed on Aug. 1, 2021. The IAU Minor Planet Center records 390 observations used to determine its orbit.

Accessibility and Exploration

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