On the Earth approach in 2015, it was observed by the Goldstone Solar System Radar and found to be a contact binary with the largest axis approximately 2 kilometers wide, and each lobe about 200–300 meters large.JPL News: Earth Flyby of 'Space Peanut' Captured in New Video http://www.jpl.nasa.gov/news/news.php?feature=4675 JPL NASA 1 August 2015 Although 1999 JD 6 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.IAU Minor Planet Center: (85989) 1999 JD6 https://www.minorplanetcenter.net/db_search/show_object?utf8=%E2%9C%93&object_id=85989 Minor Planet Center IAU 1 August 2015 July 2015 Earth passage thumb|left|Series of Goldstone Solar System radar images showing the rotation of 1999 JD 6 On 24 July 2015 1999 JD 6 came as close as 19 lunar distances to Earth.PIA19647 It was imaged by radar, and shown to be a contact binary, about 2 kilometers (1.2 miles) on its long axis.
