The 9 pages that link to Kepler's third law, each with the reason it gives.

• Orbital periodRelated: It gives the central relation between orbital size, mass, and period.

• Circular orbitRelated: For a circle, the semimajor axis is the constant orbital radius.

• Kepler's second lawRelated: Together with the first two laws, it summarizes the observed regularities of planetary orbits.

• Kepler's first lawRelated: It complements the first law by relating orbital size to elapsed time.

• Moons of HaumeaRelated: Moon periods and orbital sizes help determine Haumea’s mass.

• Dermott's lawRelated: It translates period ratios in Dermott's law into corresponding orbital-size ratios.
