Astronomers and other scientists have confirmed the presence of 146 moons orbiting the major planets of our Solar System. About one third of those moons — 53 — are in orbit around the planet Saturn
It's about one-and-three-tenths times the number of Keys on a Piano.
It's about two-thirds the number of John Wayne films.
