Key Facts


500883 (2013 JJ65) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2013 JJ65 as potentially hazardous because its orbit does not bring it close to Earth.

2013 JJ65 orbits the sun every 90,800 days (248.60 years), coming as close as 29.61 AU and reaching as far as 49.49 AU from the sun. Based on its brightness and the way it reflects light, 2013 JJ65 is probably between 88.015 to 196.807 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.

No Close Approaches

2013 JJ65's orbit is 28.70 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

2013 JJ65's orbit is determined by observations dating back to June 6, 2011. It was last officially observed on June 21, 2020. The IAU Minor Planet Center records 72 observations used to determine its orbit.

Accessibility and Exploration

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