(388188) 2006 DP14 is a highly eccentric, sub-kilometer sized and peanut-shaped asteroid, classified as near-Earth object and potentially hazardous asteroid of the Apollo group.
It was discovered by LINEAR at Lincoln Lab's ETS in Socorro, New Mexico, on 23 February 2006. On 10 February 2014, it passed 6.2 lunar distances from Earth.
2006 DP14 orbits the Sun at a distance of 0.3–2.4 AU once every 1 years and 7 months (583 days). Its orbit has an eccentricity of 0.78 and an inclination of 12° with respect to the ecliptic. As no precoveries were taken, the body's observation arc begins with its discovery observation in 2006.
The asteroid has an Earth minimum orbit intersection distance of 0.0159 AU (2,380,000 km), which corresponds to the close approach distance of 6.2 lunar distances observed in February 2014.
2006 DP14 is an assumed stony S-type asteroid.
On the night of 11 February 2014, NASA scientists conducted a radar imaging session using the 70-meter dish at Goldstone Observatory. These observations, using delay-Doppler radar imaging, revealed a 400×200 meters peanut-like shape, while the Collaborative Asteroid Lightcurve Link calculates a diameter of almost 500 meters, based on an assumed standard albedo for stony asteroids of 0.20 and an absolute magnitude of 18.9.
