- HUBBLE FOLLOWS THE ROTATION OF THE ASTEROID VESTA
-
- This is a NASA Hubble Space Telescope series of 24 images showing the
- full 5.34-hour rotation of the 325-mile diameter (525 kilometer)
- asteroid Vesta.
-
- Hubble resolves features as small as 50 miles across, allowing
- astronomers to map Vesta's geologically diverse terrain. The surface
- is a complex record of Vesta's four billion-year history. Features
- include ancient lava flows, and a gigantic impact basin that is so
- deep, it exposes the asteroid's subsurface, or mantle.
-
- This sequence was taken with Hubble's Wide Field Planetary Camera 2
- between November 28 and December 1, 1994, when Vesta was at a distance
- of 156 million miles from Earth.
-
- When combined with ground-based data, astronomers will be able to make
- the first geochemical map of Vesta's surface.
