Scientists determine the masses of planets by observing the effect of the gravitational
field of those planets on nearby objects - mainly upon their moons. By measuring the
orbital period and orbital radius of a moon about a planet, Newton's laws of motion can
be used to determine the mass of the planet. Phobos, a moon of the planet Mars, was
discovered in 1877. Its orbital radius is 9380 km and its orbital period is 0.319 days (2.77
x 104 seconds). Determine the mass of Mars based o this data.
