Scientific paper

2000 DP107 was the first Near Earth Asteroid (NEA) binary ever imaged [1]. During its 2008 return, the radar signal-to-noise ratio was 20 times higher than in 2000, which provided an opportunity to obtain very detailed images with range resolution as fine as 30 m. The 2008 observability window spanned 16 days, allowing for excellent rotational and aspect angle coverage, an ideal situation for shape modeling and binary orbit fitting. The data quality enables a precise determination of the reflex motion and component mass ratio, as well as shape modeling of both components. 2000 DP107 is a low delta-v object and so it is a favorable target for spacecraft rendezvous and sample return missions.
