Radar Imaging of Near Earth Asteroids
May 9 & 10

Radar is a very powerful astronomical technique for studying the 
physical properties and refining the orbits of near-Earth asteroids. 
The world's only two radar telescopes for imaging asteroids are at 
Arecibo, Puerto Rico, and Goldstone, California. These telescopes 
can image near-Earth asteroids with resolutions as fine as several 
meters, which greatly exceeds the finest resolution available from 
any ground- or space-based optical telescope (even the Hubble Space 
Telescope). Radar images reveal an object's size, shape, rotation 
state, and features on its surface such as craters, ridges, and even 
large boulders, and have discovered that 1/6 of near-Earth asteroids 
larger than 200 meters in diameter are double systems that revolve 
around each other, like miniature versions of the Earth and Moon, and 
that 10% of near-Earth asteroids look like gigantic peanuts, while 
others resemble muffins and potatoes!
