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.
Saturn is the sixth planet from the Sun, and the second-largest planet in our solar system.
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 into the planet in September 2017. Cassini also carried ESA's Huygens Probe, which landed on Saturn's moon Titan in 2005. From Earth, astronomers have studied Saturn with telescopes for centuries. And the Hubble Space Telescope continues ...
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. Saturn's moons range in size from larger than the planet Mercury – the giant moon Titan – to as small as a sports arena. The small moon Enceladus has a global ocean ...

NASA’s Webb and Hubble Space Telescopes have teamed up to capture new views of Saturn, revealing the planet in strikingly different ways.
Saturn is tilted also, so as the seasons change on that distant world, the change in sunlight could be causing some of the observed atmospheric changes. Like Jupiter, the solar system’s largest planet, Saturn is a “gas giant” made mostly of hydrogen and helium, although there may be a rocky core deep inside.
