Check out this video with me, Sari on Science, and the crew from the Dorrance Planetarium as we re-cap the basics of Cassini on its final mission day before plunging into Saturn’s atmosphere. #Cassinigrandfinale | Arizona Science Center

Saturn and its army of moons 🪐 ❗Saturn has 83 natural satellites that vary in size, shape, and composition. ⌛ It takes some of them half an Earth day to complete the orbit around Saturn, while others take about four Earth years to travel once around the planet. 24 of Saturn's moons are regular satellites, including 7 major satellites. They have prograde orbits not greatly inclined to Saturn's equatorial plane. The remaining 59 are irregular satellites, whose orbits are much farther from #Saturn
