Artist's depiction of Haumea's ring system. A ring around Haumea, a dwarf planet and resonant Kuiper belt member, was revealed by a stellar occultation observed on 21 January 2017. This makes it the first trans-Neptunian object found to have a ring system. [32] [33] The ring has a radius of about 2,287 km, a width of ≈ 70 km and an opacity of ...
The main rings are, working outward from the planet, C, B and A, with the Cassini Division, the largest gap, separating Rings B and A. Several fainter rings were discovered more recently. The D Ring is exceedingly faint and closest to the planet. The narrow F Ring is just outside the A Ring. Beyond that are two far fainter rings named G and E.
The rings have a reddish colour in visible and near-infrared light. The age of the ring system is unknown, possibly dating back to Jupiter's formation. At least 95 moons orbit the planet; the four largest moons—Io, Europa, Ganymede, and Callisto—orbit within the magnetosphere, and were discovered by Galileo Galilei in 1610.
J1407b is a substellar object, either a free-floating planet or brown dwarf, with a massive circumplanetary disk or ring system. It was first detected by automated telescopes in 2007 when its disk eclipsed the star V1400 Centauri, causing a series of dimming events for 56 days. The eclipse by J1407b was not discovered until 2010, by Mark Pecaut ...
Well, every 13-15 years, Saturn, the second largest planet in the solar system behind Jupiter, is angled in a way in which the edge of its thin rings are oriented toward Earth – effectively ...
The rings of Jupiter are a system of faint planetary rings. The Jovian rings were the third ring system to be discovered in the Solar System, after those of Saturn and Uranus . The main ring was discovered in 1979 by the Voyager 1 space probe [ 1 ] and the system was more thoroughly investigated in the 1990s by the Galileo orbiter. [ 2 ]
People around the world will have a chance this weekend to catch what could be the year’s most stunning view of the largest planet in our solar system. Jupiter on Saturday will shine at its ...
At least 146 moons [33] orbit the planet, of which 63 are officially named; these do not include the hundreds of moonlets in the rings. Titan, Saturn's largest moon and the second largest in the Solar System, is larger (and less massive) than the planet Mercury and is the only moon in the Solar System that has a substantial atmosphere.
