Kepler's 3rd law formula. 10) The great contribution of Tycho Brahe was to Explanation: The kepler's third law tells us: where is the orbit period and is the semi-major axis.. As we can see from the equation, the period depends only on the measure of the semi-major axis of the orbit, that is, how far a planet is from the sun.. For a circular orbit, the semi-major axis ( a) is the same as the radius for the orbit. T = 2 r 3 G M E. For an ellipse, recall that the semi-major axis is one-half the sum of the perihelion and the aphelion. B) A circle is considered to be a special type of ellipse. Simply fill in two distinct fields, and we'll find out the third one then. The cube of a planet's radius is directly related to the square of its orbital period, according to Kepler's third law.
