Constant m is the mass of the planet and r is the radius of the planet. The Gravity Recovery and Climate Experiment (GRACE) mission launched in 2002 consists of two probes, nicknamed "Tom" and "Jerry", in polar orbit around the Earth measuring differences in the distance between the two probes in order to more precisely determine the gravitational field around the Earth, and to track changes that occur over time. Uranus is an ice giant (instead of a gas giant). The acceleration due to gravity is positive wherever you care to define a "surface" of Jupiter, and 0 at the center, so there must be a net decrease over that distance.
