6235 Burney is a main-belt asteroid that was discovered on November 14, 1987, by Seiji Ueda and Hiroshi Kaneda at Kushiro.
 It is named after Venetia Phair (née "Burney") (1918–2009) who, as a girl of eleven, first suggested the name of "Pluto" for the dwarf planet (which at the time was considered a planet).
Horace Ezra Bixby (May 8, 1826 - August 1, 1912) was a steamboat pilot on the Mississippi-Missouri-Ohio river system from the late 1840s until his death in 1912.
 Bixby is notable in his own right for his high standing in his profession, for his technical contributions to it, and for his service in the American Civil War.
 However, he is best known for having had as his "cub pilot" (that is, apprentice or trainee) the young man known to him as Sam Clemens, later to become famous under his pen name as American author Mark Twain.
 Twain's descriptions of Bixby's character and pedagogic style form a good part of his memoir "Life on the Mississippi", and it was through this medium that Bixby—much to his annoyance—became well-known beyond the circles of his family, friends and profession.
Arkanar is the capital of Arkanar Kingdom on a fictional unnamed planet described in ""Hard to Be a God" ("Трудно быть богом")" by Boris and Arkady Strugatsky.
 This planet is a part of the so-called Noon Universe and presents a world in a late feudalistic/Renaissance stage (opposite to e.g. early feudalism of Saula).
 As stated, the planet has never been officially named so it is usually referred to by the name of the city where the action of the book takes place.
 Arkanar (planet) was discovered in the EN-2097 solar system in 2134 AD.
Doctor John A. Zoidberg (referred to only by his last name Zoidberg) is a fictional character in the television series "Futurama".
 He is a Decapodian, a lobster-esque alien who works as the staff doctor for "Planet Express", despite his poor understanding of human physiology and allusions to his questionable credentials.
 His character parodies the supposed wealth and automatic respect of modern doctors—for example, his incompetence at human medicine makes him extremely poor despite his profession, and he is implied to be frequently homeless when not at work.
 The Decapod (named after the actual Decapoda order of ten-footed crustaceans) are an extended parody on Yiddish culture—the bigger joke being that shellfish are not kosher.
 The writing riffs on the marine theme in a playfully absurd way, with just about any marine Arthropoda or Mollusca being implied to be akin to Zoidberg.
 Zoidberg is voiced by Billy West, who performs the character with a Yiddish-inflected accent inspired by actors George Jessel and Lou Jacobi.
Harriet Guild (1899-1992) was born in Windham, Connecticut.
 She graduated from Vassar College in 1920 and Johns Hopkins School of Medicine, class of 1925 (2nd in the class).
 Upon graduation, being a woman in a "man's" profession of the time, she was unable to find a suitable position and so Johns Hopkins hired her.
 She enjoyed an outstanding career, specializing in pediatric kidney research and treatment.
Modest Petrovich Mussorgsky (Russian: Моде́ст Петро́вич Му́соргский ; ] ; 21 March [O.S. 9 March] 1839 – 28 March [O.S. 16 March] 1881 ) was a Russian composer, one of the group known as "The Five".
 He was an innovator of Russian music in the romantic period.
 He strove to achieve a uniquely Russian musical identity, often in deliberate defiance of the established conventions of Western music.
524 Fidelio is a large minor planet with a diameter of 71 km, orbiting the Sun near the center of the main asteroid belt.
 Fidelio contains both metals and carbon (Spectral class XC).
 Concerning its name, the "Catalogue of Minor Planet Names and Discovery Circumstances" notes, "This is the name of Leonora when disguised as a man in the opera "Fidelio" (composed 1805) by the German composer Ludwig van Beethoven.
 The name dates from a period when Max Wolf assigned the names of female operatic characters to asteroids he had newly discovered.
Michael E. Brown (born June 5, 1965) is an American astronomer, who has been professor of planetary astronomy at the California Institute of Technology (Caltech) since 2003.
 His team has discovered many trans-Neptunian objects (TNOs), notably the dwarf planet Eris, the only known TNO more massive than Pluto.
 He has referred to himself as the man who "killed Pluto", because he furthered Pluto being downgraded to a dwarf planet in the aftermath of the discovery of Eris and several other probable trans-Neptunian dwarf planets.
 He is the author of "How I Killed Pluto and Why It Had It Coming", published in 2010.
 He was awarded the Kavli Prize (shared with Jane X. Luu and David C. Jewitt) for 2012 “for discovering and characterizing the Kuiper Belt and its largest members, work that led to a major advance in the understanding of the history of our planetary system"
1059 Mussorgskia is a minor planet orbiting the Sun.
 It was discovered on July 19, 1925, and initially received the designation "1925 OA".
 It is now named after Modest Mussorgsky, a Russian composer.
Written in the late 19th century by H. G. Wells and first published in "The Butterfly" (September 1899), (and collected in "The Obliterated Man and Other Stories", (Dec 1925)) A Vision of Judgment is a short story in 9 sections.
 It portrays a Last Judgment in which God and the archangel Gabriel laugh at sinners and saints alike, embarrassing them until they flee "up the sleeve of God."
 After every human soul has taken shelter there, all of humanity, "enlightened" and "in new clean bodies," is given a second chance.
 God shakes them—or rather "us"—"out of his sleeve upon the planet he had given us to live upon, the planet that whirled about green Sirius for a sun," saying "now that you understand me and each other a little better. . . .
