Proposal Title: Urgent Proposal for Arecibo Radar Imaging of near­Earth Asteroid 2006 GY2
ABSTRACT:
We propose radar imaging of recently­discovered near­Earth asteroid 2006 GY2 during its close approach within
0.017 AU on 2006 May 15­16. The proximity of the close approach and the asteroid's diameter of about 550 m (+/­
a factor of two) suggest very strong signal­to­noise ratios of about 10,000 per run that will be ideal for resolving
fine detail (at resolutions of 7.5 m/pixel) on the surface, searching for satellites, and improving the asteroid's orbit.
We plan to use range­Doppler images obtained at Arecibo and Goldstone to reconstruct a detailed model of the
asteroid's three­dimensional shape and spin state, which constrain the asteroid's origin and geologic history.
