The only planets that have rings are Saturn, Jupiter, Uranus and Neptune. Saturn has seven major rings with gaps and divisions between the rings; Jupiter has three faint rings; Uranus has 13 rings; and Neptune has six rings.Know More
Galileo Galilei discovered the rings around Saturn in 1610. Each ring is made up of billions of particles that are as small as dust and as large as mountains. Several moons exist within the gaps. Saturn's rings expand 175,000 miles.
Jupiter has faint rings around the planet. In 1979, the Voyager 2 spacecraft discovered the rings. Jupiter's ring system is made up of three parts: the gossamer rings, the halo ring and the flat main ring. The rings are made from dust created by impacts. The flat ring is 4,000 miles wide, and the halo ring is approximately 12,400 to 25,000 miles thick.
The inner, narrow rings of Uranus are dark, and its outer rings are brightly colored. In 1986, Voyager 2 confirmed that 13 rings existed, disproving the earlier belief that there were only six rings.
Voyager 2 confirmed the presence of six rings around Neptune in 1989. The three prominent arcs are named Liberty, Equality and Fraternity. The rings extend 38,525 miles from the planet.Learn more about Planets
Two planets, Venus and Mercury, are the only planets in the solar system that do not have any natural satellites or moons. Mercury, Venus, Mars and Earth are inner planets.Full Answer >
A day on Saturn is 10.7 Earth hours long, which is the amount of time it takes for the planet to make a complete rotation on it axis. Saturn makes a full orbit around the sun in a period of time equal to 29 Earth years. Saturn is about 886 million miles from the sun and is the sixth furthest planet in the solar system.Full Answer >
With an average temperature of minus 288 degrees Fahrenheit and frequent, powerful storms throughout the planet, Saturn is not hospitable to life. Unlike most planets in the Milky Way, Saturn derives its heat from its core rather than from the Sun. The planet is known as a gas giant; it is primarily composed of gases, including hydrogen and molecular helium.Full Answer >
Neptune has five planetary rings. The rings were named after astronomers that were instrumental in prime discoveries on Neptune. The names of the rings are Adams, Arago, Lassell, Le Verrier and Galle.Full Answer >
