Asteroids In Fiction
Asteroids have appeared in fiction since the 1800s, the first one— Ceres—having been discovered in 1801. A theory to explain the existence of the asteroid belt that was popular in the 1800s was that it consists of the remnants of a planet predicted by the Titius–Bode law to exist between Mars and Jupiter that had somehow been destroyed, and this was reflected in early science fiction works such as Robert Cromie's 1895 novel ''The Crack of Doom''; several works of the 1950s reused this idea to warn of the dangers of nuclear weapons. Early works also tended to depict the asteroid belt as a region that must be navigated carefully lest one's spaceship should collide with one of the asteroids, one example being Isaac Asimov's 1939 short story "Marooned off Vesta"; later works mostly recognize that the individual asteroids are very far apart and accordingly pose little danger to spacecraft, the ''Star Wars'' films being an exception to this general rule.

Asteroid
An asteroid is a minor planet of the Solar System#Inner solar system, inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 astronomical unit, AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type asteroid, C-type, M-type asteroid, M-type, and S-type asteroid, S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres (dwarf planet), Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slig ...

Jerry Pournelle
Jerry Eugene Pournelle (; August 7, 1933 – September 8, 2017) was an American scientist in the area of operations research and human factors research, a science fiction writer, essayist, journalist, and one of the first bloggers. In the 1960s and early 1970s, he worked in the aerospace industry, but eventually focused on his writing career.

Footfall
''Footfall'' is a 1985 science fiction novel by American writers Larry Niven and Jerry Pournelle. The book depicts the arrival of members of an alien species called the Fithp that have traveled to the Solar System from Alpha Centauri in a large spacecraft driven by a Bussard ramjet. Their intent is conquest of the planet Earth. Plot The alien Fithp resemble baby elephants with multiple prehensile trunks. They possess more advanced technology than humans, but did not develop any of it on their own. In the distant past on their planet, another species was dominant. The predecessor species badly damaged the environment, rendering itself and many other species extinct, but left behind their knowledge inscribed on large stone cubes from which the Fithp gained their technology. An arms race between two rival herds threatened to render the species extinct, so they wagered to see who would depart in a starship and seek a new home elsewhere. The leadership of the loser formed the ''Cht ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arthur C
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a ...

Impact Event
An impact event is a collision between astronomical objects causing measurable effects. Impact events have physical consequences and have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal effect. When large objects impact terrestrial planets such as the Earth, there can be significant physical and biospheric consequences, though atmospheres mitigate many surface impacts through atmospheric entry. Impact craters and structures are dominant landforms on many of the Solar System's solid objects and present the strongest empirical evidence for their frequency and scale. Impact events appear to have played a significant role in the evolution of the Solar System since its formation. Major impact events have significantly shaped Earth's history, and have been implicated in the formation of the Earth–Moon system. Impact events also appear to have played a significant role in the evolutionary h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert A
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and '' berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. I ...

Space Stations And Habitats In Fiction
The concepts of space stations and space habitats feature in science fiction. The difference between the two is that habitats are larger and more complex structures intended as permanent homes for substantial populations (though generation ships also fit this description, they are usually not considered space habitats as they are heading for a destination), but the line between the two is fuzzy with significant overlap and the term space station is sometimes used for both concepts. The first such artificial satellite in fiction was Edward Everett Hale's "The Brick Moon" in 1869, a sphere of bricks 61 meters across accidentally launched into orbit around the Earth with people still onboard. Space stations Space stations started appearing frequently in science fiction works following the release of the 1949 popular science book '' The Conquest of Space'' by Willy Ley, which deals with the subject. They serve several disparate functions in different works. Among these are industry, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Precipice (Bova Novel)
''The Precipice'' is a science fiction novel by Hugo Award winner Ben Bova. This novel is part of the Grand Tour series of novels. It is the first book in ''The Asteroid Wars'' series.

Plot synopsis The greenhouse effect is threatening the earth. Two rival industrialists, Dan Randolph and Martin Humphries believe that the key to earth's survival is to mine the asteroid belt and move earth's heavy industry to space. Millionaire Dan Randolf is going bankrupt, since his aerospace company, Astro Corp, is out of work due to the "greenhouse cliff" putting Earth at a higher priority than space. Cold-hearted multi-billionaire Martin Humphries shows Randolph a fully laid-out plan to reach the Asteroid Belt and mine it for its abundant metals.
