worrydream.comyoung, non-porous asteroid (if such exist) suffers extensive impact damage, the resulting fracture pattern largely defines the asteroid’s response to future impacts. The stochastic nature of collisions implies that small asteroid interiors may be as diverse as their shapes and spin states. Detailed numerical simulations of impacts,

ipnpr.jpl.nasa.govThe asteroid orbits were iteratively integrated with the positions of the planets, the Sun, and the Moon. The set of 343 asteroids is identical to the set used in DE421. The set represents 90 percent of the total mass of the main belt and contains the asteroids with the most significant ef-

Originally classified as a planet, Ceres is now designated a dwarf planet (but retains its asteroid label), along with Pluto, which was discovered in 1930; Eris, found in 2003; Haumea, found in 2004; and Makemake, found in 2005.
Ten Facts About Meteors
www.nasa.govasteroid. 2. Meteors are bits of rocks and ice ejected from comets as they move in their orbits about the sun. 3. A meteor that reaches the ground it is called a meteorite. 4. Meteor showers get their names from the constellation in where their radiant is located. Perseids come from Perseus, hence the name Perseids. 5.
