Question
Predict/Calculate The Martian moon Deimos has an orbital period that is greater than the other Martian moon, Phobos. Both moons have approximately circular orbits. (a) Is Deimos closer to or farther from Mars than Phobos? Explain. (b) Calculate the distance from the center of Mars to Deimos given that its orbital period is $1.10 \times 10^{5} \mathrm{s}$ .
Step 1
Mathematically, this can be written as: \[T^2 = k \cdot r^3\] where \(T\) is the orbital period, \(r\) is the distance from the center of the orbit, and \(k\) is a constant. Show more…

Mars has two moons, Deimos and Phobos . Deimos has an orbital radius 2.5 times larger than that of Phobos. Determine the length of time it takes Deimos to complete one orbit if it takes Phobos 0.3189 d at an orbital radius of 2.35*10^ 4 km
Mars has two moons, Phobos and Deimos. By looking through a telescope, you can easily and accurately determine the radius and period of the orbits of these moons. The radius and orbital period of the moons are: 1. Phobos: radius: 9376 km; period: 0.31891023 d 2. Deimos: radius: 23463.2 km; period: 1.263 d What is the mass of Mars given by both of these moons? (Assume that the mass of Mars is much greater than the moons.)
Mars has two moons, Phobos and Deimos. It is known that the larger moon, Phobos, has an orbital radius of $9.4 \times 10^{6} \mathrm{m}$ and a mass of $1.1 \times 10^{16} \mathrm{kg}$. Find its orbital period.
