Weborbit [ ôr ′bĭt ] Noun The path followed by a celestial body or artificial satellite as it revolves around another body due to the force of gravity. Orbits are nearly elliptical or circular in shape and are very closely approximated by Kepler's laws of planetary motion. One complete revolution of such a body. See Note at solar system. WebFor an ellipse, recall that the semi-major axis is one-half the sum of the perihelion and the aphelion. For a circular orbit, the semi-major axis ( a) is the same as the radius for the orbit. In fact, Equation 13.8 gives us Kepler’s third law if we simply replace r with a and square both sides. T 2 = 4 π 2 G M a 3.
