Saturn is the sixth planet from the Sun and the second-largest planet in our solar system. Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and helium. Saturn is not the only planet to have rings, but none are as spectacular or as complex as Saturn's.
Over historical time, objects categorized as planets have changed. The ancient Greeks counted the Earth's Moon and Sun as planets along with Mercury, Venus, Mars, Jupiter, and Saturn. Earth was not considered a planet, but rather was thought to be the central object around which all the other celestial objects orbited.
Oct 24, 2024 · By the time Cassini dove into Saturn at the end of its mission, it had observed the planet for less than half of a Saturn year. But it had also orbited the gas giant 294 times, forever changing our understanding of the Saturn system and yielding insight for understanding the entire solar system.
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.
Sep 14, 2022 · Earth is not the only place in the solar system with rain, rivers, lakes, and seas. Saturn’s moon Titan has them, too – not of water, but of liquid methane and ethane. This Earth-like world even hides an ocean of liquid water deep beneath its surface! Find out what you need to know about Titan.
Saturn is the sixth planet from our Sun (a star) and orbits at a distance of about 886 million miles (1.4 billion kilometers) from the Sun. 03 Short Day, Long Year
In April 2017, NASA's Cassini spacecraft began writing the final, thrilling chapter of its remarkable 20-year-long story of exploration: its Grand Finale. Every week, Cassini dived through the approximately 1,200-mile-wide (2,000-kilometer-wide) gap between Saturn and its rings.
Saturn's largest moon, Titan, is an icy world whose surface is completely obscured by a golden hazy atmosphere. Titan is the second largest moon in our solar system. Only Jupiter's moon Ganymede is larger, by just 2 percent. Titan is bigger than Earth's moon, and larger than even the planet Mercury.
Cassini revealed in great detail the true wonders of Saturn, a giant world ruled by raging storms and delicate harmonies of gravity. Cassini carried a passenger to the Saturn system, the European Huygens probe—the first human-made object to land on a world in the distant outer solar system.
