The Dynamical Evolution of the Asteroid Belt
The asteroid belt helps us in reconstructing the origin and the evolution of the solar system, probably better than the planets themselves. This is because the asteroid belt provides several key constraints that can be used to effectively guide the development, calibration, and validation of evolutionary models. Compared to other small-body populations, such as the Kuiper belt or Oort cloud, th...
متن کاملLanding and Mobility Concept for the Small Asteroid Lander Mascot on Asteroid 1999 Ju3
To enhance the currently studied asteroid sample return mission HAYABUSA-2 by in-situ science the Institute of Space Systems of the German Aerospace Center (DLR) is in lead of a proposal for a lander called MASCOT (Mobile Asteroid Surface Scout). Its mass of 10 kg lies in between those of the HAYABUSA small lander MINERVA (1 kg) and the legged ROSETTA comet lander PHILAE (100 kg). In the succes...
متن کاملTurning Meteorites into Rock: Constraints on Asteroid Physical Evolution
Introduction: Chondrites have been compared to terrestrial sandstones, formed by the physical accumulation of unrelated grains followed by a lithification process. Tectonics and the simple weight of overlying layers provide the conditions for lithification of sandstones on Earth. What plays this role on meteorite parent bodies? Present day asteroids cannot compact meteorites by their own self-g...
متن کاملDynamical evolution of 1036 Ganymed , the largest near - Earth asteroid
We have studied numerically the dynamical evolution of 1036 Ganymed, the largest near-Earth asteroid, by integrating the orbits of tens of " clone " particles with similar initial conditions. Typically, the orbit initially undergoes large, coupled oscillations of the eccentricity and inclination; then, Mars encounters random–walk the semimajor axis until it reaches a strong Jovian resonance; an...
متن کاملNon-gravitational perturbations and evolution of the asteroid main belt
Gravity is the most important force to affect the motion of bodies in the Solar system. At small sizes, however, additional forces must be taken into account to explain fine details of their translational and rotational motion, as well as parameters of their populations. This is because the strength of the non-gravitational perturbations typically increases as 1/D toward small sizes D. The prin...
