Topics related to "Orbital"

orbit
orbit in astronomy, path in space described by a body revolving about a second body where the motion of the orbiting bodies is dominated by their mutual gravitational attraction. Within the solar system, planets, dwarf planets, asteroids, and comets orbit the sun and satellites orbit the planets an... Read more
orbiting observatory
orbiting observatory research satellite designed to study solar radiation, electromagnetic radiation from distant stars, the earth's atmosphere , or the like. Because the atmosphere and other aspects of the earth's environment interfere with astronomical observations from the ground, especiall... Read more
molecular orbital theory
molecular orbital theory detailed explanation of how electrons are distributed in stable molecules . In the simpler valence theory of the chemical bond , each atom in a molecule is assumed to retain its own electrons. Even when electrons are shared, as in the covalent bond, it is possible to id...

inclination
inclination in astronomy, the angle of intersection between two planes, one of which is an orbital plane. The inclination of the plane of the moon's orbit is 5°9′ with respect to the plane of the ecliptic (the plane of the earth's orbit around the sun). The inclination of the plane of the... Read more
apsis
apsis (pl. apsides), point in the orbit of a body where the body is neither approaching nor receding from another body about which it revolves. Any elliptical orbit has two apsides. At the perigee the moon or other satellite is as close as it ever gets to the earth, and it begins to move away; at... Read more
