how many moons does saturn have

From 2004 to 2007, Sheppard and his colleagues used Subaru to take an extremely close look in the area around Saturn to search for undiscovered moons. Saturn’s Inner Large Moons, which orbit within the E Ring (see below), include the larger satellites Mimas, Enceladus, Tethys, and Dione. Saturn’s moons are grouped based on their size, orbits, and proximity to Saturn., Audio Podcast version: The Large Outer Moons, which orbit outside of the Saturn’s E Ring, are similar in composition to the Inner Moons – i.e. Jupiter may be the solar system’s king, but Saturn has a bigger entourage: Today, astronomers announced that they have discovered 20 more moons around Saturn, bringing its total number to 82—the most for any planet in the solar system. "We think these moons are basically showing us how chaotic the solar system was in the very distant past," Sheppard says. © 1996-2015 National Geographic Society, © 2015- However, some of its inner and outer moons are among the largest and most dramatic in the Solar System, measuring between 250 and 5000 km in diameter and housing some of greatest mysteries in the Solar System. Earth's atmosphere is also mostly nitrogen. The images were taken with the Subaru telescope, with about one hour elapsed between each image. Post was not sent - check your email addresses! Next-generation telescopes, such as the Giant Magellan Telescope being built in Chile, will likely find even more moons encircling the solar system’s gas giants. 36:20 Why do I think multicellular life is rare? 11:31 Could space be infinite at the Big Bang? Here too, the moons are similar in appearance and have orbits that range from 16 to 19 million km. The difference in these features are believed to be evidence of a major resurfacing event at some time in Rhea’s past. Meanwhile, the irregular moons in the outermost regions have orbital radii of millions of kilometers, orbital periods lasting several years, and move in retrograde orbits. Scientists have also noted the presence of polycyclic aromatic hydrocarbons in the upper atmosphere, as well as methane ice crystals. I Never Knew That Saturn Has 60 Moons! Titan is also the only large moon to have its own atmosphere, which is cold, dense, and composed primarily of nitrogen with a small fraction of methane. Last, there is the Norse group, which consists of 29 retrograde outer moons that take their names from Norse mythology. Earth's atmosphere is also mostly nitrogen. Even now, three missions to Jupiter and Saturn are in the works: NASA’s Europa Clipper; NASA’s Dragonfly mission; and the European Space Agency’s JUICE mission. Titan is also the only body in the Solar System beside Earth with bodies of liquid on its surface, in the form of methane–ethane lakes in Titan’s north and south polar regions. With an orbital radius of 527,108 km, it is the fifth-most distant of the larger moons, and takes 4.5 days to complete an orbit. And that’s not counting Saturn’s beautiful rings. Nearly three years later, astronomers have announced the discovery of 20 small moons orbiting Saturn, bringing the planet's total up to 82.
