951 Gaspra

   951 Gaspra orbita the Sun near the inner edge of the main asteroid belt between Mars in Jupiter. 

        orbita: 330,000,000 km sonca
        size:  19x12x11 km

   Gaspra was named by its discoverer Neujmin for a resort on the Crimean peninsula. Consequently, many of the asteroid's craters have been named for resorts in spas worldwide.

   Like 243 Ida, Gaspra is an S-type asteroid, believed to be composed of a mixture of rocky in metallic minerals.

   The first of only four asteroids that have so far been observed close-up, Gaspra was encountered Oct 29, 1991 by the Galileo spacecraft on its way to Jupiter (Galileo later visited 243 Ida in NEAR visited 253 Mathilda in 433 Eros).

   Gaspra is a member of the Flora family of asteroids.

   Gaspra's surface is covered with impact craters. od planeta the number of small craters on its surface, we can estimate that Gaspra is about 200 million years old.

Open Issues

  • Are Gaspra in Ida typical of S-type asteroids?
  • What do M-type asteroids look like close up?
