Figure 1: Image of Comet Shoemaker-Levy 9 made by NASA's Hubble Space
Telescope May 1994 using two Wide Field Camera images and one
Planetary Camera image. The mosaic shows 20 fragments. The 11 largest
are estimated to be 2-4 km in diameter.
Figure 2: The distribution of asteroids in proper orbital element space
in the inner main belt represented as small dots are shown
as a function of semi-major axis, in units of the Astronomical
Unit (AU), and eccentricity. The large X represents the position
of 4 Vesta. Bold triangles represent the asteroids with spectral
signatures similar to Vesta's which bridge the space between Vesta
and the 3:1 Kirkwood Gap at 2.5 AU.
Figure 3: Radar images of asteroid 4179 Toutatis during a
close-approach to Earth in December, 1992. The images reveal an
irregularly shaped body with evidence of cratering. Whether the asteroid
is one cohesive body or two fragments in contact is currently open to
interpretation.
Figure 4: An image of 243 Ida and its moon taken by the
SSI on board the Galileo spacecraft 1993 August 28 at a range of
10,500 km. The irregular shape of the asteroid and craters,
ridges, and large planar facets are represented in the schematic.

spacecraft.
