P43A:
Ceres and Vesta: Understanding the "Planets" of the Asteroid Belt I Posters

Submit an Abstract to this Session



Session ID#: 23303

Session Description:
Many of the outstanding questions about Vesta and Ceres have been addressed by analyzing data from the Dawn mission. A comprehensive mapping campaign was undertaken at both bodies, as well as studies of their compositions, geophysical properties, and interiors. Although thought to be currently geologically inactive, with surfaces modified primarily by impact craters, there is evidence for magmatic activity on Vesta, resurfacing by cryo-volcanism on Ceres, and tectonic processes on both. As data continues to be analyzed, new high-resolution observations and measurements will allow us to characterize these unique small “planets”, and gain new understanding of their place in the history of our Solar System.

We encourage abstract submissions related to geologic, spectroscopic, compositional and geophysical analyses of Ceres and Vesta. Possible topics include analyses of Dawn data, telescopic observations, analytical interior modeling, and numerical modeling of impact events and/or tectonic activity. Comparative analyses with other small bodies are welcome.
