Gaspra - Galileo

Mosaic of two images of asteroid 951 Gaspra

Mosaic of two Galileo clear-filter images of asteroid 951 Gaspra. The images were taken from about 5,300 km about 10 minutes before closest approach. This is the highest resolution of Gaspra, about 54 m/pixel. Over 600 craters larger than 100 meters in diameter can be seen in this image. Gaspra is an irregularly shaped body about 19 x 12 x 11 ]km. The north pole is at upper left. Gaspra rotates counterclockwise once every 7 hours. The visible portion shown here is about 18 km at its greatest length. (Galileo, P-40449)
