“Is the shape of the orbit of the Satellites motion around the heavenly bodies is elliptical or circular or anything else?”, “Do you think that velocity of the Satellite in space is constant?” .The answers to these can be cleared with Keplerian Laws of Planetary motion. Johannes Kepler (1571-1630) derived three laws which govern the planetary motion. This law generally applied to any two bodies in the space which interact through gravitation. He considered the more massive among the two as Primary, the other as Secondary or satellite. Kepler’s First law stats that the path followed by the secondary (Satellite) around the primary is ellipse. This law helps in finding the eccentricity ‘e’ of the ellipse with the help of semi-major axis ‘a’ and semi-minor axis ‘b’ . This Eccentricity and Semi-major axis gives the shape of the Ellipse. When the Eccentricity is zero, the path followed by the secondary over the primary is circular. Kepler’s Second law stats that for a fixed period of equal time intervals, the satellite will sweep out equal areas in orbital plane, focused at the barycenter. This law depicts that the velocity is more near perigee (the point of closest approach to the earth) position than in the apogee (the point farthest from the earth) position. Kepler’s third law stats that the square of the periodic time of the orbit is proportional to the cube of the mean distance between the two bodies. The mean distance is nothing but the Semi-major axis ‘a’ and the proportionality constant used is earth’s geocentric gravitational constant.
