He also noted that areas are equivalent when formed from the sun sweeping out to a planet's orbit in his second law.
With Poinsot, this scientist names some stellated polyhedra. This scientist names a conjecture about the average density of packing spheres. The case featuring the Inverse Square Law is a specialized form of the two-body problem named for this man. A trajectory taken by a planet that features a two-dimensional orbital plane is named for this man. He also noted that areas are equivalent when formed from the sun sweeping out to a planet's orbit in his second law. For ten points, name this formulator of three laws of planetary motion.
