Astronomy Lesson 54: Binary Stars 3; The Mass of Proxima b and Stellar Masses

We use the data from the Pale Red Dot's discovery of a planet around another star to show exactly how we link together the observational data of radial velocity observations to give us the mass and radius of a planet orbiting a distant star. We can't see the planet, but we see its effects. Therefore, we can deduce its properties. We use this to emphasize the importance of learning the masses of the stars.
