'''{{mp|(185851) 2000 DP|107}}''' is a sub-kilometer sized [[asteroid]], classified as [[potentially hazardous asteroid]] and [[near-Earth object]] of the [[Apollo asteroid|Apollo group]] that is notable because it provided evidence for [[binary asteroid]]s in the near-Earth population. The [[PROCYON]] probe developed by [[JAXA]] and the [[University of Tokyo]] was intended to flyby this asteroid before its [[ion thruster]] failed and could not be restarted.

== Discovery ==

The asteroid was discovered on 29 February 2000, by the [[Lincoln Near-Earth Asteroid Research]] (LINEAR) program at [[Lincoln Laboratory's Experimental Test Site]], near Socorro, New Mexico.<ref name="MPC-object" />

The binary nature of this asteroid was suggested from radar observations taken with the [[Goldstone Deep Space Communications Complex|Goldstone]] radar antenna on September 22 and 23, 2000, based on an observing proposal by [[Jean-Luc Margot|J.-L. Margot]] and observations by [[Steven Ostro|S. J. Ostro]] and colleagues.<ref>[http://www.cbat.eps.harvard.edu/iauc/07400/07496.html IAUC 7496: 2000 S1; {{mp|2000 DP|107}}]</ref> Confirming observations were obtained with the [[Arecibo Observatory|Arecibo telescope]] from September 30 to October 7, 2000.<ref>[http://www.cbat.eps.harvard.edu/iauc/07500/07503.html#Item2 IAUC 7503: 2000dp; Sats of minor planets]</ref>

== Orbit ==

{{mp|2000 DP|107}} orbits the Sun at a distance of 0.9–1.9&nbsp;[[Astronomical unit|AU]] once every 19 months (583 days). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.38 and an [[orbital inclination|inclination]] of 9[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" /> The body's [[observation arc]] begins with its official discovery observation, as no [[precoveries]] were taken, and no prior identifications were made.<ref name="MPC-object" />

== Binary system ==

The 800-meter-diameter primary and the 300-meter-diameter secondary orbit each other with a separation of 2.6 kilometers and a period of 1.76 days.<ref name="Margot-2002" />

The primary is spheroidal and is spinning at a rate near the breakup point for strengthless bodies. These two features were observed in multiple binary systems, suggesting that near-Earth asteroid binaries form by a mechanism involving spin-up and mass shedding.<ref name="Margot-2002" /> Currently the most generally accepted spin-up mechanism is the [[Yarkovsky–O'Keefe–Radzievskii–Paddack effect|YORP effect]].

== Physical characteristics ==

The asteroid is characterized as both a carbonaceous [[C-type asteroid|C-type]]<ref name="Dandy-2003" /> and metallic [[M-type asteroid]].<ref name="Yang-2003a" />

The density of the primary was calculated using the orbital elements of the binary system, the primary-to-secondary mass ratio, and estimates of the primary size. The primary has a low density of 1.7 g/cm<sup>3</sup>, which may indicate a "[[rubble pile]]" structure containing rocks and voids.

== Numbering and naming ==

This [[minor planet]] was [[Minor planet designation|numbered]] by the [[Minor Planet Center]] on 20 May 2008.<ref name="MPC-Circulars-Archive" /> As of 2018, it has not been [[List of named minor planets (alphabetical)|named]].<ref name="MPC-object" />
