Model of Vesta

This image shows a model of the protoplanet Vesta, using scientists' best guess to date of what the surface of the protoplanet might look like. It was created as part of an exercise for NASA's Dawn mission involving mission planners at NASA's Jet Propulsion Laboratory and science team members at the Planetary Science Institute in Tuscon, Ariz.


The images incorporate the best data on dimples and bulges of the protoplanet Vesta from ground-based telescopes and NASA's Hubble Space Telescope. The cratering and small-scale surface variations are computer-generated, based on the patterns seen on the Earth's moon, an inner solar system object with a surface appearance that may be similar to Vesta.


Vesta, located in the main asteroid belt between Mars and Jupiter, formed very early in the history of the solar system and has one of the oldest surfaces in the system.
