Asteroids and Comets
Radar provides the ability to study shape, size and spin state of asteroids and comets from the ground. Radar imaging has produced images with up to 7.5-m resolution. With sufficient data, the size, shape, spin and radar albedo of the target asteroids can be extracted.
Only 15 comets have been studied by radar, including 73P/Schwassmann-Wachmann. There have been radar observations of 321 Near-Earth asteroids and 130 Main belt asteroids.

Famous quotes containing the word comets:
“I know
No answer to the children’s cry
Of echo’s answer and the man of frost
And ghostly comets over the raised fists.”
—Dylan Thomas (1914–1953)
