(22) Kalliope I Linus
Linus, formal designation (22) Kalliope I, is an asteroid moon that orbits the large M-type asteroid 22 Kalliope. It was discovered on August 29, 2001, by astronomers Jean-Luc Margot and Michael E. Brown with the Keck telescope, in Hawaii. Another team also detected the moon with the Canada-France-Hawaii Telescope on September 2, 2001. Both telescopes are on Mauna Kea. It received the provisional designation S/2001 (22) 1, until it was named. The naming proposal appeared in the discovery paper and was approved by the International Astronomical Union in July 2003. Although the naming proposal referred to the mythological Linus, son of the muse Calliope and the inventor of melody and rhythm, the name was also meant to honor Linus Torvalds, inventor of the Linux operating system kernel, and Linus van Pelt, a character in the ''Peanuts'' comic strip. With an estimated (17 ± 1 mi) diameter, Linus is very large compared to most asteroid moons, and would be a sizable astero ...

Infobox Planet
An infobox is a digital or physical table used to collect and present a subset of information about its subject, such as a document. It is a structured document containing a set of attribute–value pairs, and in Wikipedia represents a summary of information about the subject of an article. In this way, they are comparable to data tables in some aspects. When presented within the larger document it summarizes, an infobox is often presented in a sidebar format. An infobox may be implemented in another document by transcluding it into that document and specifying some or all of the attribute–value pairs associated with that infobox, known as parameterization. Wikipedia An infobox may be used to summarize the information of an article on Wikipedia. They are used on similar articles to ensure consistency of presentation by using a common format. Originally, infoboxes (and templates in general) were used for page layout purposes. An infobox may be transcluded into an article b ...

Hawaii
Hawaii ( ; ) is an island U.S. state, state of the United States, in the Pacific Ocean about southwest of the U.S. mainland. One of the two Non-contiguous United States, non-contiguous U.S. states (along with Alaska), it is the only state not on the North American mainland, the only state that is an archipelago, and the only state in the tropics. Hawaii consists of 137 volcanic islands that comprise almost the entire Hawaiian Islands, Hawaiian archipelago (the exception, which is outside the state, is Midway Atoll). Spanning , the state is Physical geography, physiographically and Ethnology, ethnologically part of the Polynesian subregion of Oceania. Hawaii's ocean coastline is consequently the List of U.S. states and territories by coastline, fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Niihau, Kauai, Kauai, Oahu, Oahu, Molokai, Molokai, Lanai, Lānai, Kahoʻolawe, Kahoolawe, Maui, and Hawaii (island), Hawaii, a ...

Precession
Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, if the axis of rotation of a body is itself rotating about a second axis, that body is said to be precessing about the second axis. A motion in which the second Euler angle changes is called '' nutation''. In physics, there are two types of precession: torque-free and torque-induced. In astronomy, ''precession'' refers to any of several slow changes in an astronomical body's rotational or orbital parameters. An important example is the steady change in the orientation of the axis of rotation of the Earth, known as the precession of the equinoxes. Torque-free or torque neglected Torque-free precession implies that no external moment (torque) is applied to the body. In torque-free precession, the angular momentum is a constant, ...

90 Antiope
90 Antiope is a double asteroid in the outer asteroid belt. It was discovered on 1 October 1866, by Karl Theodor Robert Luther, Robert Luther. In 2000, it was found to consist of two almost-equally-sized bodies orbiting each other. At average diameters of about 88 km and 84 km, both components are among the 500 largest asteroids. Antiope is a member of the Themis family of asteroids that share similar orbital elements. Naming The asteroid's proper name comes from Greek mythology, but it is disputed whether this is Antiope (Amazon), Antiope the Amazon or Antiope (mother of Amphion), Antiope the mother of Amphion and Zethus. Since the discovery of Antiope's binary nature, the name "Antiope" technically refers to the slightly larger of the two components, with the smaller component bearing the provisional designation S/2000 (90) 1. However, the name "Antiope" is also used to refer to the binary system as a whole. Properties The most remarkable feature of Antiope i ...

617 Patroclus
617 Patroclus ( ) is a large binary Jupiter trojan asteroid. It is a dark D-type asteroid and a List of slow rotators (minor planets), slow rotator, due to the 103-hour orbital period of its two components. It is one of five Jupiter trojan asteroids targeted by the ''Lucy (spacecraft), Lucy'' space probe, and is scheduled for a flyby (spaceflight), flyby in 2033. Patroclus was discovered on 17 October 1906, by astronomer August Kopff at the Heidelberg Observatory in Germany, and was named after Patroclus in Greek mythology. It was the second trojan to be discovered and the only member of the Trojan camp named after a Greek figure, as the convention of naming one 'camp' after Greek figures of the Trojan War and the other after Trojan figures had not yet been established. Patroclus was long thought to be one of the 617 Patroclus#Diameter and albedo, largest Jupiter trojans, with a diameter on the order of 150 km. However, in 2001 it was discovered to be a binary asteroid of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Belt
The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies called asteroids or minor planets. The identified objects are of many sizes, but much smaller than planets, and, on average, are about one million kilometers (or six hundred thousand miles) apart. This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System. The asteroid belt is the smallest and innermost circumstellar disc in the Solar System. Classes of small Solar System bodies in other regions are the near-Earth objects, the centaurs, the Kuiper belt objects, the scattered disc objects, the sednoids, and the Oort cloud objects. About 60% of the main belt mass is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid be ...

Peanuts
''Peanuts'' (briefly subtitled ''featuring Good ol' Charlie Brown'') is a print syndication, syndicated daily strip, daily and Sunday strip, Sunday American comic strip written and illustrated by Charles M. Schulz. The strip's original run extended from 1950 to 2000, continuing in reruns afterward. ''Peanuts'' is among the most popular and influential in the history of comic strips, with 17,897 strips published in all, making it "arguably the longest story ever told by one human being". At the time of Schulz's death in 2000, ''Peanuts'' ran in over 2,600 newspapers, with a readership of roughly 355 million across 75 countries, and had been translated into 21 languages. It helped to cement the Yonkoma, four-panel gag strip as the standard in the United States, and together with its merchandise earned Schulz more than $1 billion. Following successful TV and theatrical adaptations over the years, a The Peanuts Movie, movie adaptation was released by Blue Sky Studios in 20 ...

Calliope
In Greek mythology, Calliope ( ; ) is the Muse who presides over eloquence and epic poetry; so called from the ecstatic harmony of her voice. Hesiod and Ovid called her the "Chief of all Muses". Mythology Calliope had two famous sons, OrpheusHoopes And Evslin,''The Greek Gods''. , , 1995, page 77. "His father was a Thracian king; his mother the muse Calliope. For a while, he lived on Parnassus with his mother and his eight beautiful aunts and there met Apollo who was courting the laughing muse Thalia. Apollo was taken with Orpheus, gave him his little golden lyre, and taught him to play. And his mother taught him to make verses for singing." and Linus of Thrace, Linus, by either Apollo or King Oeagrus of Thrace. She taught Orpheus verses for singing. According to Hesiod, she was also the wisest of the Muses, as well as the most assertive. Calliope married Oeagrus in Pimpleia, a town near Mount Olympus.
