Strong chaos induced by close encounters with Ceres and Vesta
We consider the full Solar System including (1) Ceres and some of the main asteroids, (2) Pallas, (4) Vesta, (7) Iris, and (324) Bamberga. We show that close encounters among these small bodies induce strong chaotic behavior in their orbits and in those of many asteroids that are much more chaotic than previously thought. Even if space missions will allow very precise measurements of the positi...
متن کاملForced obliquities and moments of inertia of Ceres and Vesta
0019-1035/$ see front matter 2011 Published by doi:10.1016/j.icarus.2010.09.002 ⇑ Corresponding author. Address: MS 183-301, Jet Oak Grove Drive, Pasadena, CA 91109, USA. E-mail addresses: [email protected] (B.G. B Nimmo). We examine models of secular variations in the orbit and spin poles of Ceres and Vesta, the two most massive bodies in the main asteroid belt. If the spin poles are fu...
متن کاملDawn Discovery mission to Vesta and Ceres: Present status
Dawn, the ninth Discovery mission, is a journey to the main belt asteroids Vesta and Ceres to attempt to understand the building blocks of the solar system and the processes occurring at the solar system s earliest epoch. It does this with a spacecraft that utilizes ion propulsion to reach its targets and to maneuver into orbit about these bodies. It carries a framing camera, a visible and infr...
متن کاملDawn Mission to Vesta and Ceres Symbiosis between Terrestrial Observations and Robotic Exploration
The initial exploration of any planetary object requires a careful mission design guided by our knowledge of that object as gained by terrestrial observers. This process is very evident in the development of the Dawn mission to the minor planets 1 Ceres and 4 Vesta. This mission was designed to verify the basaltic nature of Vesta inferred both from its reflectance spectrum and from the composit...
