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:

    The novel is not “a crazy quilt of bits”; it is a logical sequence of psychological events: the movements of stars may seem crazy to the simpleton, but wise men know the comets come back.
    Vladimir Nabokov (1899–1977)
