In gravitationally bound systems, the orbital speed of an astronomical body or object (e.g. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter or, if one body is much more massive than the other bodies of the system combined, its speed relative to the … See more In the following, it is thought that the system is a two-body system and the orbiting object has a negligible mass compared to the larger (central) object. In real-world orbital mechanics, it is the system's … See more The transverse orbital speed is inversely proportional to the distance to the central body because of the law of conservation of angular momentum, … See more For the instantaneous orbital speed of a body at any given point in its trajectory, both the mean distance and the instantaneous distance are taken into account: See more • Escape velocity • Delta-v budget • Hohmann transfer orbit • Bi-elliptic transfer See more For orbits with small eccentricity, the length of the orbit is close to that of a circular one, and the mean orbital speed can be approximated either from observations of the orbital period and the semimajor axis of its orbit, or from knowledge of the masses of the two bodies … See more The closer an object is to the Sun the faster it needs to move to maintain the orbit. Objects move fastest at perihelion (closest approach … See more WebFrom the relationship F centripetal = F centrifugal We note that the mass of the satellite, m s, appears on both sides, geostationary orbit is independent of the mass of the satellite. r (Orbital radius) = Earth's equatorial radius + Height of the satellite above the Earth surface r = 6,378 km + 35,780 km r = 42,158 km r = 4.2158 x 107 m Speed ...

WebMay 19, 2000 · Orbital velocity is the velocity needed to achieve balance between gravity's pull on the satellite and the inertia of the satellite's motion -- the satellite's tendency to keep going. This is approximately 17,000 mph (27,359 kph) at an altitude of 150 miles (242 kilometers). Without gravity, the satellite's inertia would carry it off into space ... today show on streaming
