2014 JJ57

2014 JJ57 is a mid-sized asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2014 JJ57 as potentially hazardous because its orbit does not bring it close to Earth. 2014 JJ57 orbits the sun every 6,780 days (18.56 years), coming as close as 4.97 AU and reaching as far as 9.04 AU from the sun. Based on its brightness and the way it reflects light, 2014 JJ57 is probably between 7.666 to 17.141 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Boston.
