单词 orbital velocity
释义 orbital velocity(orbital speed)
The speed of a satellite, spacecraft, or other body travelling in an orbit around the earth or around some other celestial body. If the orbit is elliptical, the orbital speed, v, is given by:
v = v[gR2(2/r - 1/a)],
where g is the accceleration of free fall, R is the radius of the orbited body, a is the semimajor axis of the orbit, and r is the distance between the orbiting body and the centre of mass of the system. If the orbit is circular,
r = a
and
v = v(gR2/r
)
