A single mathematical equation allows astronomers to weigh and measure distant stars
Kepler's Third Law provides a vital cosmic scale that enables scientists to calculate the precise mass of distant stars by simply observing the orbital motion of objects circling them.
Johannes Kepler's Third Law of Planetary Motion acts as a universal scale for the cosmos. By measuring how long it takes a planet or a companion star to complete one orbit, astronomers can determine the total mass of the system with incredible accuracy.
