Whether a moon, a planet, or some man-made satellite, every satellite's motion is governed by the same physics principles and described by the same mathematical equations. A Satellite is a Projectile. The fundamental principle to be understood concerning satellites is that a satellite is a projectile. That is to say, a satellite is an object ...
Kepler’s Laws of Planetary Motion. Kepler's First Law. The orbit of each planet about the Sun is an ellipse with the Sun at one focus. Figure \ (\PageIndex {1}\): (a) An ellipse is a closed curve such that the sum of the distances from a point on the curve to the two foci \ ( (f_1 and f_2) \) is a constant.
Kepler’s Second Law. Each planet moves so that an imaginary line drawn from the Sun to the planet sweeps out equal areas in equal times (see Figure 2). Kepler’s Third Law. The ratio of the squares of the periods of any two planets about the Sun is equal to the ratio of the cubes of their average distances from the Sun.

Space debris left from old satellites and their launchers is becoming a hazard to other satellites. (a) Calculate the speed of a satellite in an orbit 900 km above Earth’s surface. (b) Suppose a loose rivet is in an orbit of the same radius that intersects the satellite’s orbit at an angle of [latex]\text{90º}[/latex] relative to Earth.

Kepler proved that the orbit, or path that a satellite took around a body, was an ellipse. As we already know, an ellipse is defined by the semi major (a) and semi minor (b) axes, as shown in Figure 3.2 (a). The centre of the ellipse is represented by C.
