2060 Chiron is a ringed small Solar System body in the outer Solar System, orbiting the Sun between Saturn and Uranus.Discovered in 1977 by Charles Kowal, it was the first-identified member of a new class of objects now known as centaurs—bodies orbiting between the asteroid belt and the Kuiper belt.
The Q1R ring's coincidental location at these resonances implies they play a key role in maintaining the ring without having it accrete into a single moon. [10] In particular, the confinement of rings to the 1:3 spin-orbit resonance may be common among ringed small Solar System bodies, as it has been previously seen in Chariklo and Haumea. [10]
51 Pegasi b, officially named Dimidium / d ɪ ˈ m ɪ d i ə m /, is an extrasolar planet approximately 50 light-years (15 parsecs) away in the constellation of Pegasus.It was the first exoplanet to be discovered orbiting a main-sequence star, [2] the Sun-like 51 Pegasi, and marked a breakthrough in astronomical research.
Venus is the second planet from the Sun.It is a terrestrial planet and is the closest in mass and size to its orbital neighbour Earth.Venus has by far the densest atmosphere of the terrestrial planets, composed mostly of carbon dioxide with a thick, global sulfuric acid cloud cover.
55 Cancri e (abbreviated 55 Cnc e, also known as Janssen / ˈdʒænsən /) is an exoplanet orbiting a Sun -like host star, 55 Cancri A. The mass of the exoplanet is about eight Earth masses and its diameter is about twice that of the Earth. [3] 55 Cancri e was discovered on 30 August 2004, thus making it the first super-Earth discovered around ...
The two outermost planets complete an orbit in 41 and 54.7 days, resulting in four orbits for every three. The innermost planet, meanwhile, completes six orbits in exactly the time the outermost ...
Ring system. The moons Prometheus (right) and Pandora (left) orbit just inside and outside, respectively, the F ring of Saturn, but only Prometheus is thought to function as a shepherd moon. A ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as gas, dust, meteoroids, planetoids or moonlets ...
Mercury (planet) Surface temp. Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the ancient Roman god Mercurius (Mercury), god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as Mars.
