Introduction

Confirming Kepler’s 3rd Law Lab                Adnan Masood

Introduction:

        Johannes Kepler was a German astronomer who is best known for his three laws on planetary motion. He lived from 1571-1630, and his works all took place during the scientific revolution (Johannes Kepler).

        He was most famous for coming up with his three laws of planetary motion. His first law states that all planets move in an elliptical orbit with two foci, one of those foci being a star. His second law states that if one was to connect a line from a star to a planet, at equal times,

    None of the possible errors listed earlier, however, could have been severe enough to completely alter the data. Therefore, the results received were quite reliable and allowed sufficient conclusions to be made that supported the original hypothesis.
