Gravitation and Kepler’s Laws
Ex 1: Consider Kepler’s Third Law, (R3/T2 = constant) for our solar system using our Sun as mass
MSun = 1.99 x 1030 kg. Use this data to determine the Kepler constant (Ksun) for this solar system.
[Taffel6.18a]
Ex 2: Using Kepler’s constant for our Sun, Determine the period of a satellite moving around the Sun
between the orbits of the Earth and Mars at a mean distance of 2.0 x 1011 m from the Sun ?
