Saturn is the sixth planet from the Sun and the second largest planet in our solar system.
Saturn is a massive ball made mostly of hydrogen and helium. It's surrounded by a beautiful ring system. It's the farthest planet from Earth discovered by the unaided human eye.
Four robotic spacecraft have visited Saturn.
Saturn has dozens of officially recognized moons in its orbit, more than any other planet.
Saturn's moons range in size from Titan, which is larger than the planet Mercury – to a moon that's as small as a sports arena.

Cassini studied Saturn from orbit for 13 years before its human engineers on Earth transformed it into an atmospheric probe for its spectacular final plunge
Four robotic spacecraft have visited Saturn. NASA's Pioneer 11 provided the first close look in September 1979. NASA's twin Voyager 1 and Voyager 2 spacecraft followed up with flybys nine months apart in 1980 and 1981. But it wasn't until Cassini arrived in orbit in 2004 that our understanding of Saturn really started to take shape.
From Earth, astronomers have studied Saturn with telescopes for centuries. And the Hubble Space Telescope continues to uncover new details from its perch in Earth orbit.
Pioneer 11 was the first spacecraft to study Saturn up close.
The twin Voyagers launched in 1977 to visit Jupiter and Saturn, and never stopped.
Voyager 2 flew by Saturn and returned spectacular photos and unprecedented data.
For more than a decade, Cassini shared the wonders of Saturn and its family of icy moons.

The farthest planet from Earth discovered by the unaided human eye, Saturn has been known since ancient times. The planet is named for the Roman god of agriculture and wealth, who was also the father of Jupiter.
Saturn's environment is not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
While planet Saturn is an unlikely place for living things to take hold, the same is not true of some of its many moons. Satellites like Enceladus and Titan, home to internal oceans, could possibly support life.
Saturn Moons
Saturn has 274 confirmed moons in its orbit, far more than any other planet in our solar system.
Saturn has 274 confirmed moons in its orbit, far more than any other planet in our solar system. In March 2025, astronomers confirmed the discovery of 128 small moons around Saturn — adding to the already large moon count.
