Asteroid capture is an orbital insertion of an asteroid around a larger planetary body. When asteroids, small rocky bodies in space, are captured, they become natural satellites , [ 1 ] [ failed verification – see discussion ] specifically either an irregular moon if permanently captured, or a temporary satellite .
Gravitational capture occurs when one object enters a stable orbit around another (typically referring to natural orbits rather than orbit insertion of a spacecraft with an orbital maneuvers). Asteroid capture turns a star-orbiting asteroid into an irregular moon if captured permanently, or a temporary satellite .
Sizes can be estimated by timing the lengths of star occultations (when an asteroid passes directly in front of a star). Radar imaging can yield good information about asteroid shapes and orbital and rotational parameters, especially for near-Earth asteroids. Spacecraft flybys can provide much more data than any ground or space-based ...
