Orbits of four different planets around the same star are shown.
The masses of the planets, expressed in terms of the mass M of the
smallest planet, can be found in the included table, while the
relative sizes of the orbits can be determined from the diagram.
Assume that the mass of the star is much larger than the mass of
the planets. Rank the period T of the four orbits, from longest to
shortest.

Two very small planets are orbiting a much larger star. Planet A orbits the star with a period T. Planet B circles the star at four times the distance of Planet A, but Planet B is four times as massive as Planet A. Planet B orbits the star with a period of A) T/4 B) 8T C) 4T D) T E) 16T
Two newly discovered planets follow circular orbits around a star in a distant part of the galaxy. The orbital speeds of the planets are determined to be 45.2 km/s and 55.1 km/s. The slower planet's orbital period is 6.27 years. (a) What is the mass of the star? (b) What is the orbital period of the faster planet, in years?
Two newly discovered planets follow circular orbits around a star in a distant part of the galaxy. The orbital speeds of the planets are determined to be 42.6 km/s and 64.2 km/s. The slower planet's orbital period is 6.93 years. (a) What is the mass of the star? (b) What is the orbital period of the faster planet, in years?
Two newly discovered planets follow circular orbits around a star in a distant part of the galaxy. The orbital speeds of the planets are determined to be 43.4 km/s and 57.2 km/s. The slower planet's orbital period is 7.50 years. (a) What is the mass of the star? ______ kg (b) What is the orbital period of the faster planet, in years? _______yr
Two planets are orbiting around the same star. Planet A has four times the mass of planet B. Planet A is located twice further from the star than planet B. When comparing the force of gravity affecting both planets, what is the value of the following ratio: FG on A FG on B O A) 4 B) 2 C) 1 D) 1/2 O E) 1/4
Question Two newly discovered planets follow circular orbits around a star in a distant part of the galaxy. The orbital speeds of the planets are determined to be 42.1 km/s and 59.1 km/s.

The following diagrams are the same as those from Part A. This time, rank the planets from left to right based on the amount of time it takes each to complete one orbit, from longest to shortest. If you think that two (or more) of the diagrams should be ranked as equal, drag one on top of the other(s) to show this equality. (Distances are to scale, but planet and star sizes are not.)

Two very small planets are orbiting a much larger star. Planet A orbits the star with a period TA. Planet B circles the star at four times the distance of Planet A, but Planet B is four times as massive as Planet A. Planet B orbits the star with a period of:
