Stephano (moon)
Stephano ( ) is a retrograde irregular satellite of Uranus. It was discovered by Brett J. Gladman, ''et al.'' in 1999, and given the provisional designation S/1999 U 2. Confirmed as Uranus XX, it was named after the drunken butler in William Shakespeare's play '' The Tempest'' in August 2000. The orbital parameters suggest that it may belong to the same dynamic cluster as Caliban, suggesting common origin.

Caliban (moon)
Caliban is the second-largest retrograde irregular satellite of Uranus. It was discovered on 6 September 1997 by Brett J. Gladman, Philip D. Nicholson, Joseph A. Burns, and John J. Kavelaars using the 200-inch Hale telescope together with Sycorax and given the temporary designation S/1997 U 1. Designated Uranus XVI, it was named after the monster character in William Shakespeare's play '' The Tempest''. Orbit Caliban follows a distant orbit, more than 10 times further from Uranus than the furthest regular moon Oberon. Its orbit is retrograde, moderately inclined and slightly eccentric. The orbital parameters suggest that it may belong to the same dynamic cluster as Stephano and Francisco, suggesting common origin. The diagram illustrates the orbital parameters of the retrograde irregular satellites of Uranus (in polar co-ordinates) with the eccentricity of the orbits represented by the segments extending from the pericentre to the apocentre.

Irregular Satellites
In astronomy, an irregular moon, irregular satellite or irregular natural satellite is a natural satellite following a distant, inclined, and often eccentric and retrograde orbit. They have been captured by their parent planet, unlike regular satellites, which formed in orbit around them. Irregular moons have a stable orbit, unlike temporary satellites which often have similarly irregular orbits but will eventually depart. The term does not refer to shape as Triton is a round moon, but is considered irregular due to its orbit. As of December 2022, 149 irregular moons are known, orbiting all four of the outer planets (Jupiter, Saturn, Uranus and Neptune). The largest of each planet are Himalia of Jupiter, Phoebe of Saturn, Sycorax of Uranus, and Triton of Neptune. It is currently thought that the irregular satellites were captured from heliocentric orbits near their current locations, shortly after the formation of their parent planet. An alternative theory, that they originated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moons Of Uranus
Uranus, the seventh planet of the Solar System, has 27 known moons, most of which are named after characters that appear in, or are mentioned in, the works of William Shakespeare and Alexander Pope. Uranus's moons are divided into three groups: thirteen inner moons, five major moons, and nine irregular moons. The inner and major moons all have prograde orbits, while orbits of the irregulars are mostly retrograde. The inner moons are small dark bodies that share common properties and origins with Uranus's rings. The five major moons are ellipsoidal, indicating that they reached hydrostatic equilibrium at some point in their past (and may still be in equilibrium), and four of them show signs of internally driven processes such as canyon formation and volcanism on their surfaces. The largest of these five, Titania, is 1,578 km in diameter and the eighth-largest moon in the Solar System, about one-twentieth the mass of the Earth's Moon. The orbits of the regular moons are near ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kaare Aksnes
Kaare Aksnes (born 25 March 1938 in Kvam in Hardanger) is a professor at the Institute for Theoretical Astrophysics at the University of Oslo. Personal life He was born in Kvam, Hordaland as a brother of the chemist Gunnar Aksnes. His parents were farmers. In 1959 he married teacher Liv Kristin Marøy. Career He finished his secondary education in 1956, and graduated with the cand.real. degree in 1963, having studied in both Bergen and Oslo. From 1964 to 1965 he was a research assistant at Harestua. He then worked in the United States for several years, and took the Ph.D. at Yale University in 1969. His doctor's thesis is today a standard work within estimating the course of planets, moons, meteors, comets and artificial sounds. His work is among other things used by NASA's Voyager sounds to Jupiter, and he received the NASA Group Achievement Award for his work. After several years at the Center for Astrophysics Harvard & Smithsonian in Cambridge, Massachusetts he returned fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brian G
H. Brian Griffinas shown in Brian Griffin's House of Payne is a fictional character from the American animated television series ''Family Guy''. An anthropomorphic white labrador retriever voiced by Seth MacFarlane, he is one of the show's main characters as a member of the Griffin family. He primarily works in the series as a less-than-adept writer struggling to find himself, attempting essays, novels, screenplays, and newspaper articles. He first appeared on television, along with the rest of the family, in a 15-minute short on December 20, 1998. Brian was created and designed by MacFarlane himself. MacFarlane was asked to pitch a pilot to the Fox Broadcasting Company, based on ''The Life of Larry'' and ''Larry & Steve'', two shorts made by MacFarlane featuring a middle-aged character named Larry and an intellectual dog, Steve. These two are now considered as Peter and Brian. After the pilot was given the green light, the Griffin family appeared in the episode " Death Has a ...

Joseph A
Joseph is a common male given name, derived from the Hebrew Yosef (יוֹסֵף). "Joseph" is used, along with "Josef", mostly in English, French and partially German languages. This spelling is also found as a variant in the languages of the modern-day Nordic countries. In Portuguese and Spanish, the name is "José". In Arabic, including in the Quran, the name is spelled '' Yūsuf''. In Persian, the name is "Yousef". The name has enjoyed significant popularity in its many forms in numerous countries, and ''Joseph'' was one of the two names, along with ''Robert'', to have remained in the top 10 boys' names list in the US from 1925 to 1972. It is especially common in contemporary Israel, as either "Yossi" or "Yossef", and in Italy, where the name "Giuseppe" was the most common male name in the 20th century. In the first century CE, Joseph was the second most popular male name for Palestine Jews. In the Book of Genesis Joseph is Jacob's eleventh son and Rachel's first son, and k ...
