{{#invoke:Infobox|infobox}} (85989) 1999 JD6 is an Aten asteroid, near-Earth object, and potentially hazardous object in the inner Solar System that makes frequent close approaches to Earth and Venus. On the Earth approach in 2015, it was observed by the Goldstone Observatory and found to be a contact binary with the largest axis approximately 2 kilometers wide, and each lobe about 200–300 meters large.<ref name=radarobs>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Although 1999 JD6 in its current orbit never passes closer than 0.047 AU to Earth, it is listed as a potentially hazardous object because it is large and might pose a threat in the future.

The asteroid is well-observed, having been observed over 2,000 times over a length of over 25 years, and was assigned a numeric designation in August 2004.<ref name=mpcorbit>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
