Homework Answers
by keplers third law T2 is directly proportional to r3 . or T is directly proportiona to r3/2.
where T = time period and r = radius of orbit .
since X has time period of 0.62 earth years so X is closer to sun than earth.
and Y has time period 1.9 earth years so Y is farther from sun than earth.
so the correct answer is D.

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.

In Lecture 4, we discussed Kepler’s third law relatingthe orbital period of a planet (p) to the semi-major axis (orbital distance, a) of its orbit(p2= a3). We can apply this law as long the object orbits the Sun or another object of the same mass, and the units of orbital period are in (Earth) years and the orbital distance is in Astronomical Units(AU). [1AU is equal to the distance between the Earth and the Sun]. [Note: Newton extended this law...
