Bleriot (moon)
Bleriot (or Blériot), is the informal name for a propeller moonlet within Saturn's A Ring. It is about across, making it the largest of these propeller moonlets. It has been tracked by the ''Cassini'' Imaging Team since 2005. Bleriot has been subject to some scientific studies due to its large size and has helped scientists improve their understanding the interactions between objects within Saturn's rings. The orbit of Bleriot has some anomalies such as that it sometimes is much further behind or ahead than is predicted to be. The name comes from French aviator Louis Blériot, who was the first person to fly across the English Channel. Due to its small size, Bleriot cannot be directly imaged, it can only be noticed by the "propeller-shaped" disturbances it creates around it.

Cassini–Huygens
''Cassini–Huygens'' ( ), commonly called ''Cassini'', was a space research, space-research mission by NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI) to send a space probe to study the planet Saturn and its system, including its Rings of Saturn, rings and Moons of Saturn, natural satellites. The Large Strategic Science Missions, Flagship-class robotic spacecraft comprised both NASA's ''Cassini'' space probe and ESA's Huygens (spacecraft), ''Huygens'' lander (spacecraft), lander, which landed on Saturn's largest moon, Titan (moon), Titan. ''Cassini'' was the fourth space probe to visit Saturn and the first to enter its orbit, where it stayed from 2004 to 2017. The two craft took their names from the astronomers Giovanni Cassini and Christiaan Huygens. Launched aboard a Titan IV, Titan IVB/Centaur on October 15, 1997, ''Cassini'' was active in space for nearly 20 years, spending its final 13 years orbiting Saturn and studying the planet and its system a ...

Saturn
Saturn is the sixth planet from the Sun and the second largest in the Solar System, after Jupiter. It is a gas giant, with an average radius of about 9 times that of Earth. It has an eighth the average density of Earth, but is over 95 times more massive. Even though Saturn is almost as big as Jupiter, Saturn has less than a third its mass. Saturn orbits the Sun at a distance of , with an orbital period of 29.45 years. Saturn's interior is thought to be composed of a rocky core, surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and an outer layer of gas. Saturn has a pale yellow hue, due to ammonia crystals in its upper atmosphere. An electrical current in the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than Earth's, but has a magnetic moment 580 times that of Earth because of Saturn's greater size. Saturn's magnetic field strength is about a twen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rings Of Saturn
Saturn has the most extensive and complex ring system of any planet in the Solar System. The rings consist of particles in orbit around the planet made almost entirely of water ice, with a trace component of Rock (geology), rocky material. Particles range from micrometers to meters in size. There is no consensus as to what mechanism facilitated their formation: while investigations using theoretical models suggested they formed early in the Solar System's existence, newer data from ''Cassini–Huygens, Cassini'' suggests a more recent date of formation. In September 2023, astronomers reported studies suggesting that the rings of Saturn may have resulted from the collision of two moons "a few hundred million years ago". Though light reflected from the rings increases Saturn's apparent brightness, they are not themselves visible from Earth with the naked eye. In 1610, the year after Galileo Galilei's first observations with a telescope, he became the first person to observe Saturn' ...

Synchronous Rotation
Tidal locking between a pair of co-orbiting astronomical bodies occurs when one of the objects reaches a state where there is no longer any net change in its rotation rate over the course of a complete orbit. In the case where a tidally locked body possesses synchronous rotation, the object takes just as long to rotate around its own axis as it does to revolve around its partner. For example, the same side of the Moon always faces Earth, although there is some variability because the Moon's orbit is not perfectly circular. Usually, only the satellite is tidally locked to the larger body. However, if both the difference in mass between the two bodies and the distance between them are relatively small, each may be tidally locked to the other; this is the case for Pluto and Charon, and for Eris and Dysnomia. Alternative names for the tidal locking process are gravitational locking, captured rotation, and spin–orbit locking. The effect arises between two bodies when their g ...

Moonlets
A moonlet, minor moon, minor natural satellite, or minor satellite is a particularly small natural satellite orbiting a planet, dwarf planet, or other minor planet. Up until 1995, moonlets were only hypothetical components of Saturn's F-ring structure, but in that year, the Earth passed through Saturn's ring plane. The Hubble Space Telescope and the European Southern Observatory both captured objects orbiting close or near the F-ring. In 2004, Cassini caught an object 4–5 kilometers in diameter on the outer ring of the F-ring and then 5 hours later on the inner F-ring, showing that the object had orbited. Several different types of small moons have been called moonlets: * A belt of objects embedded in a planetary ring, especially around Saturn, such as those in the A Ring, S/2009 S 1 in the B Ring ( "propeller" moonlets), and those in the F Ring * Occasionally asteroid moons, such as those of 87 Sylvia * Flashes seen near Jupiter's moon Amalthea that is likely debris ej ...

Louis Blériot
Louis Charles Joseph Blériot ( , also , ; 1 July 1872 – 1 August 1936) was a French aviator, inventor, and engineer. He developed the first practical headlamp for cars and established a profitable business manufacturing them, using much of the money he made to finance his attempts to build a successful aircraft. Blériot was the first to use the combination of hand-operated joystick and foot-operated rudder control as used to the present day to operate the aircraft flight control system, aircraft control surfaces. Blériot was also the first to make a working, powered, piloted monoplane.Gibbs-Smith 1953, p. 239 In 1909 he became world-famous for making the first aeroplane flight across the English Channel, winning the prize of £1,000 offered by the ''Daily Mail'' newspaper. He was the founder of Blériot Aéronautique, a successful aircraft manufacturing company. Early years Born at No.17h rue de l'Arbre à Poires (now rue Sadi-Carnot) in Cambrai, Louis was the first of five ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English Channel
The English Channel, also known as the Channel, is an arm of the Atlantic Ocean that separates Southern England from northern France. It links to the southern part of the North Sea by the Strait of Dover at its northeastern end. It is the busiest Sea lane, shipping area in the world. It is about long and varies in width from at its widest to at its narrowest in the Strait of Dover."English Channel". ''The Columbia Encyclopedia'', 2004. It is the smallest of the shallow seas around the continental shelf of Europe, covering an area of some . The Channel aided the United Kingdom in becoming a naval superpower, serving as a natural defence against invasions, such as in the Napoleonic Wars and in the World War II, Second World War. The northern, English coast of the Channel is more populous than the southern, French coast. The major languages spoken in this region are English language, English and French language, French.

Peggy (moonlet)
Peggy is the informal name for a former moonlet in the outermost part of Saturn's Ring A, orbiting away from the planet. The moonlet was discovered by the ''Cassini'' Imaging Team in 2013 and it may likely be exiting Saturn's A Ring. No direct image of Peggy has ever been made. Similar moons to Peggy include Bleriot, Earhart and Santos-Dumont among others. Etymology The name of the moonlet comes from the mother-in-law of Carl D. Murray, a professor at the Queen Mary University of London. Murray named it after his mother-in-law because it was her 80th birthday at the time. Discovery The moonlet was first discovered in 2013, although its discovery was possible in 2012. ''Cassini'' took 2 images of the edge of Saturn's A Ring, thereby ruling out it being a cosmic ray artifact. There were disturbances at the edges of Saturn's A Ring, with one of these being approximately 20% brighter than its surroundings. There were also protuberances at the edge of the usually smooth A Ring. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S/2009 S 1
S/2009 S 1 is a Rings of Saturn#Propeller_moonlets, moonlet embedded in the outer part of Saturn's Rings of Saturn#B Ring, B Ring, orbiting away from the planet. The moonlet was discovered by the Cassini–Huygens, ''Cassini'' Imaging Team during the Saturnian equinox event on 26 July 2009, when the ''Cassini'' spacecraft imaged the moonlet casting a -long shadow onto the B Ring. With a diameter of , it is most likely a long-lived solid body, which would count it as the smallest and innermost known moon of Saturn. Discovery was first identified by the Cassini–Huygens, ''Cassini'' Imaging Team led by Carolyn Porco, in a single image taken by the ''Cassini'' spacecraft approximately from Saturn on 26 July 2009 11:30 UTC. The moonlet was discovered during Saturn's 2009 equinox, when it cast an approximately -long shadow on the planet's B ring. Characteristics Based on the shadow's width, the ''Cassini'' Imaging Team infer a diameter of for . The presence of a shadow sugge ...
