Images of asteroid 3 Juno taken with the Hooker telescope show what appears to be a 96-km-wide crater. The crater is visible as a darkened area in the lower left quadrant in the 833 nm and 934 nm images.
3 Juno is the ninth largest asteroid and third to be discovered, in 1804 by the German astronomer Karl Harding (1765–1834). Surface maps of Juno made from observations by the 100-inch Hooker Telescope at Mount Wilson Observatory in 2003 show the presence of what may be a 96-kilometer (60-mile) wide crater.
