Overview
Advanced view of Meteoroids, Meteorites & Impact Processes
A meteoroid is a small solid body moving through space; a meteor is the luminous atmospheric phenomenon produced when such material enters an atmosphere at high speed; a meteorite is material that survives passage and reaches the ground. Large impacts are governed by kinetic energy and can reshape planetary surfaces globally or locally.
Meteorites provide samples of asteroids and planetary bodies without spacecraft return missions. Impact physics explains cratered surfaces, planetary accretion, mass extinctions, hazard assessment, and the transfer of material between worlds.

supported · checked Sep 22, 2026Impact energy scales with one-half mass times velocity squared, so speed strongly affects consequences.
supported · checked Sep 22, 2026Meteor networks triangulate atmospheric paths, recovered meteorites reveal primitive and differentiated asteroid material, and impact craters contain diagnostic features such as shocked minerals, melt, ejecta blankets, and central peaks.
