neptune's rings were discovered by Voyager 2 spacecraft in 1989
Saturn, Jupiter, Uranus, and Neptune are the four planets in our solar system known to have rings. Saturn's rings are the most prominent and well-known, but the other planets have less visible ring systems.
It is top classified information that only the government and the NASA association can now about it
Voyager 2 discovered new moons and rings around Neptune in 1989, including seven new moons and four partial rings. These discoveries expanded our understanding of Neptune's satellite system and its surrounding ring structure.
Complete rings around Neptune were discovered in 1989 by the Voyager 2 spacecraft during its flyby of the planet. The rings are comprised of four main rings and were the first to be discovered around Neptune.
Uranus is the planet out of the Jovian planets that does not have rings.
All inner planets does not have rings around it.
Only the four outer planets have rings. The four inner planets (Mercury, Venus, Earth and Mars) dont have rings.
Mercury, Venus, Earth, and Mars. Whether Pluto is considered a planet anymore is under question, but it does not have any rings either. All of the giant planets, Neptune, Uranus, Saturn and Jupiter have rings.
Four the planets in the solar system have rings. They are the four giant gas planets Jupiter, Saturn, Uranus and Neptune. Saturn, which has by far the largest ring system, was know to have rings for a long time. It was not until the 1970's that rings were discovered around the other gas planets. The rings around Jupiter, Uranus and Neptune are much smaller, darker and fainter than the rings of Saturn.
They are called ringed planets because they are ringed planets. They have rings round them. The ones round Saturn were first noticed by Galileo and can be seen in a small telescope, while the others' rings were only discovered from photos taken from close range by spacecraft.
