Pluto - Wikipedia
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune.It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun.It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris.Like other Kuiper belt objects, Pluto is made primarily of ice and rock ...
Planetary Rings – Astronomy - Maricopa Open Digital Press
Most of the gaps in Saturn’s rings, and also the location of the outer edge of the A Ring, result from gravitational resonances with small inner moons. A resonance takes place when two objects have orbital periods that are exact ratios of each other, such as 1:2 or 2:3.

Rings are composed of vast numbers of individual particles orbiting so close to a planet that its gravitational forces could have broken larger pieces apart or kept small pieces from gathering together. Saturn’s rings are broad, flat, and nearly continuous, except for a handful of gaps.

The Outer Planets: Rings - Laboratory for Atmospheric and Space …
SUMMARY: All four jovian planets are surrounded by a set of rings. These rings are made up of rock, ice, and dust particles that range in size from microscopically small to the size of a house. How Are Rings Formed? This majestic image of Saturn was taken by the Cassini spacecraft as it passed through the shadow of the giant planet.
Webb rings in the holidays with the ringed planet Uranus
Dec 19, 2023 · With its exquisite sensitivity, Webb captured Uranus's dim inner and outer rings, including the elusive Zeta ring - the extremely faint and diffuse ring closest to the planet. It also imaged many of the planet's 27 known moons, even seeing some small moons within the rings.
Rings of Saturn - Wikipedia
The full set of rings, imaged as Saturn eclipsed the Sun from the vantage of the Cassini orbiter, 1.2 million km (¾ million miles) distant, on 19 July 2013 (brightness is exaggerated). Earth appears as a dot at 4 o'clock, between the G and E rings.. The rings of Saturn are the most extensive and complex ring system of any planet in the Solar System.They consist of countless small particles ...
NASA’s Hubble Celebrates Decade of Tracking Outer Planets
Dec 9, 2024 · Encountering Neptune in 1989, NASA’s Voyager mission completed humankind’s first close-up exploration of the four giant outer planets of our solar system. Collectively, since their launch in 1977, the twin Voyager 1 and Voyager 2 spacecraft discovered that Jupiter, Saturn, Uranus, and Neptune were far more complex than scientists had imagined. There was a lot […]
