If you're interested in using the more exact form of Kepler's third law of planetary motion, then press the advanced mode button, and enter the planet's mass, m. Note that the difference would be too tiny to notice, and you might need to change the units to a smaller measure (e.g., seconds, kilograms, or feet). So, to convert this to All we need to do is make two forces equal to each other: centripetal force and gravitational force (you can find more information about the latter in the gravitational force calculator). In practice, we can sometimes write it in its simpler form, P2 = a3. 35) Kepler's third law, p2 = a3, means that A) a planet's period does not depend on the eccentricity of its orbit. 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.. ; The second Kepler's law: a segment joining a planet and the Sun covers equal areas in equal intervals of time. The second property of an ellipse defines the difference between this shape and a circle. B) stellar parallax Note: When calculating the constant, Kepler assumed the orbit was circular and the radius was the orbit's average radius. 47) Which of the following best explains the success of the central African rainfall-prediction technique of observing the waxing crescent Moon?
