Dorothy (Charonian Crater)
Dorothy Crater is the largest known impact basin on Pluto's moon Charon. The crater was discovered by the '' New Horizons'' space probe in 2015 during its flyby of Pluto and its moons. It was named after Dorothy Gale from the novel ''The Wonderful Wizard of Oz''. The crater is located near Charon's north pole, and overlaps the edge of Mordor Macula.

New Horizons
''New Horizons'' is an Interplanetary spaceflight, interplanetary space probe that was launched as a part of NASA's New Frontiers program. Engineered by the Johns Hopkins University Applied Physics Laboratory (APL) and the Southwest Research Institute (SwRI), with a team led by Alan Stern, the spacecraft was launched in 2006 with the primary mission to perform a Planetary flyby, flyby study of the Pluto system in 2015, and a secondary mission to fly by and study one or more other Kuiper belt objects (KBOs) in the decade to follow, which became a mission to 486958 Arrokoth. It is the List of artificial objects leaving the Solar System, fifth space probe to achieve the escape velocity needed to leave the Solar System. On January 19, 2006, ''New Horizons'' was launched from Cape Canaveral Space Force Station by an Atlas V rocket directly into an Earth-and-solar Escape velocity, escape trajectory with a speed of about . It was the fastest (average speed with respect to Earth) man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorothy Gale
Dorothy Gale is a fictional character created by American author L. Frank Baum as the protagonist in many of his ''Oz'' novels. She first appears in Baum's classic 1900 children's novel ''The Wonderful Wizard of Oz'' and reappears in most of its sequels. In addition, she is the main character in various adaptations, notably the classic 1939 film adaptation of the novel, '' The Wizard of Oz''. In later novels, the Land of Oz steadily becomes more familiar to her than her homeland of Kansas. Dorothy eventually goes to live in an apartment in the Emerald City's palace but only after her Aunt Em and Uncle Henry have settled in a farmhouse on its outskirts, unable to pay the mortgage on their house in Kansas. Dorothy's best friend Princess Ozma, ruler of Oz, officially makes her a princess of Oz later in the novels. Appearances In literature In the Oz books, Dorothy is raised by her aunt and uncle in the bleak landscape of a Kansan farm. Whether Aunt Em or Uncle Henry is Dorothy's ...

Pluto
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of trans-Neptunian object, bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is slightly less massive than Eris (dwarf planet), Eris. Like other Kuiper belt objects, Pluto is made primarily of ice and rock and is much smaller than the inner planets. Compared to Moon, Earth's moon, Pluto has only one sixth its mass and one third its volume. Pluto has a moderately orbital eccentricity, eccentric and inclined orbit, ranging from from the Sun. Light from the Sun takes 5.5 hours to reach Pluto at its average distance (). Pluto's eccentric orbit periodically brings it closer to the Sun than Neptune, but a stable orbital resonance prevents them from colliding. Pluto has moons of Pluto, five known moons: Charon (moon), Charon, the larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charon (moon)
Charon ( or ), known as (134340) Pluto I, is the largest of the five known natural satellites of the dwarf planet Pluto. It has a mean radius of . Charon is the sixth-largest known trans-Neptunian object after Pluto, Eris, Haumea, Makemake and Gonggong. It was discovered in 1978 at the United States Naval Observatory in Washington, D.C., using photographic plates taken at the United States Naval Observatory Flagstaff Station (NOFS). With half the diameter and one eighth the mass of Pluto, Charon is a very large moon in comparison to its parent body. Its gravitational influence is such that the barycenter of the Plutonian system lies outside Pluto, and the two bodies are tidally locked to each other. The reddish-brown cap of the north pole of Charon is composed of tholins, organic macromolecules that may be essential ingredients of life. These tholins were produced from methane, nitrogen and related gases which may have been released by cryovolcanic eruptions on the moon, o ...

Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

The Wonderful Wizard Of Oz
''The Wonderful Wizard of Oz'' is a children's novel written by author L. Frank Baum and illustrated by W. W. Denslow. It is the first novel in the Oz series of books. A Kansas farm girl named Dorothy ends up in the magical Land of Oz after she and her pet dog Toto are swept away from their home by a tornado. Upon her arrival in Oz, she learns she cannot return home until she has destroyed the Wicked Witch of the West. The book was first published in the United States in May 1900 by the George M. Hill Company. In January 1901, the publishing company completed printing the first edition, a total of 10,000 copies, which quickly sold out. It had sold three million copies by the time it entered the public domain in 1956. It was often reprinted under the title ''The Wizard of Oz'', which is the title of the successful 1902 Broadway musical adaptation as well as the classic 1939 live-action film. The ground-breaking success of both the original 1900 novel and the 1902 Broadway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mordor Macula
Mordor Macula is the informal name for a large red area about in diameter near the north pole of Charon, Pluto's largest moon. It is named after the black land called Mordor in J.R.R. Tolkien's ''The Lord of the Rings''. Origin The origin of Mordor Macula is not completely understood. It may be a deposit of frozen gases captured from Pluto's escaping atmosphere, a large impact basin, or both. A leading hypothesis is that nitrogen and methane escape from Pluto and are then deposited into the cold poles of Charon, where scattered ultraviolet light then transforms the molecules into tholins. This hypothesis implies that a similar red spot should exist on Charon's south pole as welland indirect evidence suggests this is true.
