Radar Imaging of Seven Near-Earth Asteroids in January-April 2005

We prop ose delay-Doppler radar imaging, physical mo deling, satellite searches, and orbit refinement of near-Earth asteroids (NEAs) 7889 (1994 LX), 22753 (1998 WT), 30825 (1990 TG1), 1999 HF1, 1999 RR28, 2004 QT24, and 2004 RF84 during January-April 2005. We seek to improve constraints on the orbital parameters, mass, and bulk density of binary ob ject 1999 HF1, which may b e the largest known NEA binary. Two of the targets may b e close to 4 km in diameter; four are very strong kilometer-sized ob jects; and one has a basaltic comp osition. Six of the ob jects will b e detected by radar for the first time and four are classified as "Potentially Hazardous" by the Minor Planet Center.
