Quick Summary

Gaspra
Gaspra Asteroid Gaspra, composite of two images taken by the Galileo spacecraft on October 29, 1991. Galileo observed some 600 impact craters on Gaspra, from the large concavity visible on the lower right to craters as small as 100 metres (330 feet) in diameter. The asteroid's irregular shape and fracture lines suggest that it was once part of a larger body.

Gaspra is an S-class asteroid that was the first to be studied up close by the Galileo spacecraft in 1991. It is an irregularly shaped body measuring approximately 19 × 12 × 11 km (12 × 7.5 × 6.8 miles). Galileo's images revealed Gaspra's surface to be heavily cratered, indicating a history of impacts. This observation provided valuable insights into the physical characteristics of asteroids and the processes of space weathering, which alters the surface properties of celestial bodies through exposure to solar wind, radiation, and micrometeorite impacts.12
