Total Time Requested: 87.5 Hours
Proposal Title: Radar imaging of seven near­Earth asteroids in June­September 2005
ABSTRACT:
We propose delay­Doppler radar imaging, physical modeling, satellite searches, and orbit refinement of near­Earth
asteroids (NEAs) 5660 (1974 MA), 22771 (1999 CU3), 1992 UY4, 2002 EX12, 2002 SR41, 2003 CY18, and 2003
YN107 during June­September 2005. Highlights include the first known Earth quasi­satellite, which is also a
Yarkovsky e#ect candidate; two objects that could be close to 2 km in diameter; and one kilometer­sized NEA that
is the strongest known target this year. Six objects will be detected by radar for the first time and two are
classified as ''Potentially Hazardous'' by the Minor Planet Center.
