Enterprise detect a strange planet made of unusual materials.
Sensor readings give both the radius and the mass of the planet, and the ship's computer calculates the planet's density to be higher than anything heretofore discovered. A hoodlum standing on a tall building throws a stone vertically down from the roof at a given speed.

Course, it'd be a heckuva lot shorter as the crow flies.
