WebFor an elliptical orbit, the semi-major axis \(a\) is used instead of the radius for a circular orbit \(r\). The semi-major axis is equal to half the diameter of the longest part of an ellipse. In a circular orbit, the satellite will move at a constant speed throughout the orbit. However, when you measure the instantaneous speed at different ...

WebThe orbit of the Moon is a nearly circular ellipse about the Earth (the semimajor and semiminor axes are 384,400 km and 383,800 km, respectively: a difference of only 0.16%). The equation of the ellipse yields an eccentricity of 0.0549 and perigee and apogee distances of 362,600 km and 405,400 km respectively (a difference of 12%).
WebIt travels around our planet once every 27.322 days in an elliptical orbit, an elongated circle.
