Mars, the fourth planet from the Sun, has appeared as a setting in works of fiction since at least the mid-1600s. Trends in the planet's portrayal have largely been influenced by advances in planetary science. It became the most popular celestial object in fiction in the late 1800s, when it became clear that there was no life on the Moon. The predominant genre depicting Mars at the time was utopian fiction. Around the same time, the mistaken belief that there are canals on Mars emerged and made its way into fiction, popularized by Percival Lowell's speculations of an ancient civilization having constructed them. The War of the Worlds, H. G. Wells's novel about an alien invasion of Earth by sinister Martians, was published in 1897 and went on to have a major influence on the science fiction genre.
During the late 19th and early 20th centuries, it was erroneously believed that there were "canals" on the planet Mars. These were a network of long straight lines in the equatorial regions from 60° north to 60° south latitude on Mars, observed by astronomers using early telescopes without photography.
J.-H. Rosny aîné was the pen name of Joseph Henri Honoré Boex, a Belgian author considered one of the founding figures of modern science fiction.
The planet Venus has been used as a setting in fiction since before the 19th century. Its opaque cloud cover gave science fiction writers free rein to speculate on conditions at its surface—a "cosmic Rorschach test", in the words of science fiction author Stephen L. Gillett. The planet was often depicted as warmer than Earth but still habitable by humans. Depictions of Venus as a lush, verdant paradise, an oceanic planet, or fetid swampland, often inhabited by dinosaur-like beasts or other monsters, became common in early pulp science fiction, particularly between the 1930s and 1950s. Some other stories portrayed it as a desert, or invented more exotic settings. The absence of a common vision resulted in Venus not developing a coherent fictional mythology, in contrast to the image of Mars in fiction.
An extraterrestrial or alien is a lifeform that did not originate on Earth. The word extraterrestrial means "outside Earth". Extraterrestrials are a common theme in modern science-fiction, and also appeared in much earlier works such as the second-century parody True History by Lucian of Samosata.
The Moon has appeared in fiction as a setting since at least classical antiquity. Throughout most of literary history, a significant portion of works depicting lunar voyages has been satirical in nature. From the late 1800s onwards, science fiction has successively focused largely on the themes of life on the Moon, first Moon landings, and lunar colonization.
George Chetwynd Griffith-Jones was a British writer. He was active mainly in the science fiction genre—or as it was known at the time, scientific romance—in particular writing many future-war stories and playing a significant role in shaping that emerging subgenre. For a short period of time, he was the leading science fiction author in his home country both in terms of popularity and commercial success.
The First Men in the Moon by the English author H. G. Wells is a scientific romance, originally serialised in The Strand Magazine and The Cosmopolitan from November 1900 to June 1901 and published in hardcover in 1901. Wells called it one of his "fantastic stories". The novel recounts a journey to the Moon by the two protagonists: a businessman narrator, Mr. Bedford; and an eccentric scientist, Mr. Cavor. Bedford and Cavor discover that the Moon is inhabited by a sophisticated extraterrestrial civilisation of insect-like creatures they call "Selenites". The inspiration seems to come from the famous 1865 book by Jules Verne, From the Earth to the Moon, and the opera by Jacques Offenbach from 1875. Verne's novel also uses the word "Selenites" to describe inhabitants of the Moon.
Terraforming is well represented in contemporary literature, usually in the form of science fiction, as well as in popular culture. While many stories involving interstellar travel feature planets already suited to habitation by humans and supporting their own indigenous life, some authors prefer to address the unlikeliness of such a concept by instead detailing the means by which humans have converted inhospitable worlds to ones capable of supporting life through artificial means.
Jupiter, the largest planet in the Solar System, has appeared in works of fiction across several centuries. The way the planet has been depicted has evolved as more has become known about its composition; it was initially portrayed as being entirely solid, later as having a high-pressure atmosphere with a solid surface underneath, and finally as being entirely gaseous. It was a popular setting during the pulp era of science fiction. Life on the planet has variously been depicted as identical to humans, larger versions of humans, and non-human. Non-human life on Jupiter has been portrayed as primitive in some works and more advanced than humans in others.
Saturn has made appearances in fiction since the 1752 novel Micromégas by Voltaire. In the earliest depictions, it was portrayed as having a solid surface rather than its actual gaseous composition. In many of these works, the planet is inhabited by aliens that are usually portrayed as being more advanced than humans. In modern science fiction, the Saturnian atmosphere sometimes hosts floating settlements. The planet is occasionally visited by humans and its rings are sometimes mined for resources.
Pluto has appeared in fiction as a setting since shortly after its 1930 discovery, albeit infrequently. It was initially comparatively popular as it was newly discovered and thought to be the outermost object of the Solar System and made more fictional appearances than either Uranus or Neptune, though still far fewer than other planets. Alien life, sometimes intelligent life and occasionally an entire ecosphere, is a common motif in fictional depictions of Pluto. Human settlement appears only sporadically, but it is often either the starting or finishing point for a tour of the Solar System. It has variously been depicted as an originally extrasolar planet, the remnants of a destroyed planet, or entirely artificial. Its moon Charon has also appeared in a handful of works.
Asteroids have appeared in fiction since at least the late 1800s, the first one—Ceres—having been discovered in 1801. They were initially only used infrequently as writers preferred the planets as settings. The once-popular Phaëton hypothesis, which states that the asteroid belt consists of the remnants of the former fifth planet that existed in an orbit between Mars and Jupiter before somehow being destroyed, has been a recurring theme with various explanations for the planet's destruction proposed. This hypothetical former planet is in science fiction often called "Bodia" in reference to Johann Elert Bode, for whom the since-discredited Titius–Bode law that predicts the planet's existence is named.
Uranus has been used as a setting in works of fiction since shortly after its 1781 discovery, albeit infrequently. The earliest depictions portrayed it as having a solid surface, whereas later stories portrayed it more accurately as a gaseous planet. Its moons have also appeared in a handful of works. Both the planet and its moons have experienced a slight trend of increased representation in fiction over time.
Edison's Conquest of Mars is an 1898 science fiction novel by American astronomer and writer Garrett P. Serviss. It was written as a sequel to Fighters from Mars, an unauthorized and heavily altered version of H. G. Wells's 1897 story The War of the Worlds. It has a place in the history of science fiction for its early employment of themes and motifs that later became staples of the genre.
Fictional planets of the Solar System have been depicted since the 1700s—often but not always corresponding to hypothetical planets that have at one point or another been seriously proposed by real-world astronomers, though commonly persisting in fiction long after the underlying scientific theories have been refuted. Vulcan was a planet hypothesized to exist inside the orbit of Mercury between 1859 and 1915 to explain anomalies in Mercury's orbit until Einstein's theory of general relativity resolved the matter; it continued to appear in fiction as late as the 1960s. Counter-Earth—a planet diametrically opposite Earth in its orbit around the Sun—was originally proposed by the ancient Greek philosopher Philolaus in the fifth century BCE, and has appeared in fiction since at least the late 1800s. It is sometimes depicted as very similar to Earth and other times very different, often used as a vehicle for satire, and frequently inhabited by counterparts of the people of Earth. Following the discovery of the first asteroids in the early 1800s, it was suggested that the asteroid belt might be the remnants of a planet predicted by the Titius–Bode law to exist between Mars and Jupiter that had somehow been destroyed; this hypothetical former fifth planet is known as Phaëton in astronomy and often dubbed "Bodia" in science fiction. Bodia was popular in the pulp era of science fiction, where it was often depicted as similar to Earth and inhabited by humans who might occasionally be the ancestors of humans on Earth, and stories about its destruction became increasingly common following the invention of the atomic bomb in 1945. Additional planets in the outer reaches of the Solar System, such as a ninth planet beyond Neptune or especially a tenth beyond Pluto, appear regularly. Many different names for this hypothetical outermost planet have been used, the most common being "Persephone". Some stories depict so-called rogue planets that do not orbit any star entering the Solar System from without, typically on a collision course with Earth. Less frequently, fictional planets appear in other locations, such as between Venus and Earth or inside a hollow Earth. Similarly, fictional moons appear in some works; fictional additional moons of the Earth largely fell out of favour with the advent of the Space Age.
The War of the Worlds is a science fiction novel by English author H. G. Wells. It was written between 1895 and 1897, and serialised in Pearson's Magazine in the UK and Cosmopolitan magazine in the US in 1897. The full novel was first published in hardcover in 1898 by William Heinemann. The War of the Worlds is one of the earliest stories to detail a conflict between humankind and an extraterrestrial race. The novel is the first-person narrative of an unnamed protagonist in Surrey and his younger brother who escapes to Tillingham in Essex as London and southern England is invaded by Martians. It is one of the most commented-on works in the science fiction canon.
Biology appears in fiction, especially but not only in science fiction, both in the shape of real aspects of the science, used as themes or plot devices, and in the form of fictional elements, whether fictional extensions or applications of biological theory, or through the invention of fictional organisms. Major aspects of biology found in fiction include evolution, disease, genetics, physiology, parasitism and symbiosis (mutualism), ethology, and ecology.
Imagining Mars: A Literary History is a 2011 non-fiction book by science fiction scholar Robert Crossley. The book chronicles the history of Mars in fiction, and to a lesser extent in culture. The overarching thesis of the work is that the scientific understanding of Mars and the versions of the planet imagined in works of fiction have developed in parallel and influenced each other. It covers a timeframe spanning from the pre-telescope era up to the present day, especially the time period after 1877. Particular attention is paid to the influence of amateur astronomer Percival Lowell (1855–1916), who popularized the myth of Martian canals in the public consciousness, and science fiction author H. G. Wells (1866–1946) who wrote the seminal 1897 novel The War of the Worlds. The book charts how the depiction of Mars changed throughout the second half of the 1900s in response to successive advances in planetary science, while noting that some authors preferred to continue portraying the planet in a nostalgic way that was by then scientifically outdated.
A Plunge into Space is an 1890 science fiction novel by Irish author Robert Cromie. It describes a voyage to Mars, where Earthlings find a utopia that is so perfect as to be boring. It received mostly positive reviews upon release and likely sold well. The second edition was published in 1891 with a preface attributed to the French science fiction author Jules Verne; modern scholars have concluded that it was likely written by somebody else. Cromie later accused fellow writer H. G. Wells of plagiarising key plot elements from the book for his 1900–1901 serial The First Men in the Moon; Wells denied ever having heard of Cromie or the book.
