Episode notes

Pluto has a moon except the center of mass of Pluto and its moon is outside. For Earth, our center masses within Earth's surface between the Earth's moons. So we can think of we being a primary and then the moon going around us. There's a very rare object called an equal mass binary binary because they are orbiting the common center of mass.

Neil has his own asteroid?! On this episode, Neil deGrasse Tyson and comic co-host Marcia Belsky answer fan questions about different types of asteroids with Marina Brozovic, orbital dynamicist at NASA’s Jet Propulsion Laboratory.
