Breakdown: How a Planet Weighs a Star

A remarkable method in astronomy uses transiting exoplanets to measure the average density of the parent star. By comparing this value to other ways of measuring a star's density, astronomers can learn more about the planet, such as its orbital shape. Prof Kipping breaks down how this is possible in a simplified way and explains how "Asterodensity Profiling" is becoming an important tool in astronomy.
