Arecibo Radar Imaging of Six Near-Earth Asteroids During June-September

2010
ABSTRACT:
Radar is the best and most efficient method to investigate significant numbers of near-earth asteroids (NEA), as it allows for far more scientific return than optical observations at a fraction of the cost of a spacecraft mission. Previous Arecibo studies of NEAs have lead to significant advances in studies of exotic ob jects such as super-fast rotator 1998 KY26, non-principal axis rotator 1999 JM8, and triple system 2001 SN263. We propose to conduct radar imaging, satellite searches, and physical characterization of six NEAs with close approaches between June and September 2010. This group includes potentially hazardous asteroids (1999 JD6, Minos), a candidate for possible Yarkovsky effect detection (2002 BF25), and asteroids with eccentric orbits (2007 XB10, 1998 UO1, 2002 CY46). As previous studies indicate 1/6 of NEAs larger than 200 m are binary, it is probable this study might discover that one of these targets is actually binary system.
