Determine the following statement is Ture or False. Explain briefly.
A satellite moves around a planet in an elliptical orbit. The ratio of the speed of the satellite at the closest distance to that at the farthest distance from the planetcan be obtained from Kepler’s third law.
Homework Answers
False
The ratio of the speed of the satellite at the closest distance to that at the farthest distance from the planet is obtained from Kepler's SECOND law, NOT Third Law.
Kepler's second law states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. This is formulated in terms of speed.
On the other hand, third law relates the period and radius.

A previously undiscovered planet B is estimated to have a period of rotation (around the Sun) of 100 Earth years. Using Kepler’s third law, calculate its average distance from the Sun. Which known planet’s orbit is closest to this planet B? If a planetary body G is 100 AU distance away from the Sun, its period of rotation in Earth years (assuming it is still gravitationally tied to our sun) will be:__________________________ PLEASE SHOW WORK AND EXPLAIN STEPS.
