Orbital Velocity: Formula, Definition, Derivation and Calculation
WebUnder standard assumptions the orbital speed ( ) of a body traveling along an elliptic orbit can be computed from the Vis-viva equation as: where: is the standard gravitational parameter, is the distance between the orbiting bodies. is the length of the semi-major axis. The velocity equation for a hyperbolic trajectory is . Energy [ edit] WebIn order to change orbital speed, an object must change the radius of its orbit at the same time, to maintain a stable orbit. Planets further from the Sun orbit more slowly Artificial satellites ... WebPutting our rocket on an L_z = 0 Lz = 0 trajectory therefore means decelerating by the Earth's orbital speed, about 30 km/s. For any of our ordinary L_z \neq 0 Lz = 0 orbits the rocket will have non-zero speed at Earth's radius, so we can do better than the straight line. For the other four options, we can think purely in terms of orbital energy. phobos cleaned
