Query: Who coined the term asteroid?
The first asteroid to be discovered, Ceres, was originally considered to be a new planet.[note 1] This was followed by the discovery of other similar bodies, which, with the equipment of the time, appeared to be points of light, like stars, showing little or no planetary disc, though readily distinguishable from stars due to their apparent motions. This prompted the astronomer Sir William Herschel to propose the term "asteroid",[note 2] coined in Greek as ἀστεροειδής, or asteroeidēs, meaning 'star-like, star-shaped', and derived from the Ancient Greek ἀστήρ astēr 'star, planet'. In the early second half of the nineteenth century, the terms "asteroid" and "planet" (not always qualified as "minor") were still used interchangeably. [note 3]
Sometimes, the nickname for the Yansheng coin also includes the so-called ""flower coin"" or ""patterned coin"" (). They are alternatively referred to as "play coins" (wanqian, 玩钱) in China. Historically the term "Yansheng coin" was more popular but in modern China and Taiwan the term "flower coin" has become the more common name.
The minor planets beyond Jupiter's orbit are sometimes also called "asteroids", especially in popular presentations.[note 5] However, it is becoming increasingly common for the term "asteroid" to be restricted to minor planets of the inner Solar System.[47] Therefore, this article will restrict itself for the most part to the classical asteroids: objects of the asteroid belt, Jupiter trojans, and near-Earth objects.
Ceres is the largest object in the asteroid belt.
It is sometimes assumed that Ceres has been "re"classified as a dwarf planet, and that it is therefore no longer considered an asteroid. For example, a news update at Space.com spoke of "Pallas, the largest asteroid, and Ceres, the dwarf planet formerly classified as an asteroid", whereas an IAU question-and-answer posting states, "Ceres is (or now we can say it was) the largest asteroid", though it then speaks of "other asteroids" crossing Ceres' path and otherwise implies that Ceres is still considered an asteroid. The Minor Planet Center notes that such bodies may have dual designations. The 2006 IAU decision that classified Ceres as a dwarf planet never addressed whether it is or is not an asteroid. Indeed, the IAU has never defined the word 'asteroid' at all, having preferred the term 'minor planet' until 2006, and preferring the terms 'small Solar System body' and 'dwarf planet' after 2006. Lang (2011) comments "the [IAU has] added a new designation to Ceres, classifying it as a dwarf planet. ... By [its] definition, Eris, Haumea, Makemake and Pluto, as well as the largest asteroid, 1 Ceres, are all dwarf planets", and describes it elsewhere as "the dwarf planet–asteroid 1 Ceres". NASA continues to refer to Ceres as an asteroid, as do various academic textbooks.
Out of all those who say they coined the term, Ashish Gupta, COO of Evalueserve has the best claim. Published authors have credited him for coining the term in their works.
As other objects were discovered in the neighborhood of Ceres, it was realized that Ceres represented the first of a new class of objects. In 1802, with the discovery of 2 Pallas, William Herschel coined the term "asteroid" ("star-like") for these bodies, writing that "they resemble small stars so much as hardly to be distinguished from them, even by very good telescopes". As the first such body to be discovered, Ceres was given the designation 1 Ceres under the modern system of minor-planet designations. By the 1860s, the existence of a fundamental difference between asteroids such as Ceres and the major planets was widely accepted, though a precise definition of "planet" was never formulated.
The definition of "planet", since the word was coined by the ancient Greeks, has included within its scope a wide range of celestial bodies. Greek astronomers employed the term "asteres planetai" (ἀστέρες πλανῆται), "wandering stars", for star-like objects which apparently moved over the sky. Over the millennia, the term has included a variety of different objects, from the Sun and the Moon to satellites and asteroids.
In 2006, the term "small Solar System body" was also introduced to cover both most minor planets and comets.[note 4][42] Other languages prefer "planetoid" (Greek for "planet-like"), and this term is occasionally used in English especially for larger minor planets such as the dwarf planets as well as an alternative for asteroids since they are not star-like.[43] The word "planetesimal" has a similar meaning, but refers specifically to the small building blocks of the planets that existed when the Solar System was forming. The term "planetule" was coined by the geologist William Daniel Conybeare to describe minor planets,[44] but is not in common use. The three largest objects in the asteroid belt, Ceres, Pallas, and Vesta, grew to the stage of protoplanets. Ceres is a dwarf planet, the only one in the inner Solar System.
The existence of the opposition surge was described in 1956 by Tom Gehrels during his study of the reflected light from an asteroid. Gehrels' later studies showed that the same effect could be shown in the moon's brightness. He coined the term "opposition effect" for the phenomenon, but the more intuitive "opposition surge" is now more widely used.
It was at this time that the term "Cantopop" was first coined. The "Billboard" correspondent Hans Ebert, who had earlier coined the term "Cantorock" in 1974, noted a change in its style to something similar to British-American soft rock, therefore started to use the term Cantopop instead in 1978.
The term "BLEVE" was coined by three researchers at Factory Mutual, in the analysis of an accident there in 1957 involving a chemical reactor vessel. Anthony Santos was one of the Factory Mutual chemical engineers who coined the term.
An asteroid family is a population of asteroids that share similar proper orbital elements, such as semimajor axis, eccentricity, and orbital inclination. The members of the families are thought to be fragments of past asteroid collisions. An asteroid family is a more specific term than asteroid group whose members, while sharing some broad orbital characteristics, may be otherwise unrelated to each other.
When found, asteroids were seen as a class of objects distinct from comets, and there was no unified term for the two until "small Solar System body" was coined in 2006. The main difference between an asteroid and a comet is that a comet shows a coma due to sublimation of near surface ices by solar radiation. A few objects have ended up being dual-listed because they were first classified as minor planets but later showed evidence of cometary activity. Conversely, some (perhaps all) comets are eventually depleted of their surface volatile ices and become asteroid-like. A further distinction is that comets typically have more eccentric orbits than most asteroids; most "asteroids" with notably eccentric orbits are probably dormant or extinct comets.[45]
Asteroids in the and Sun–Jupiter Lagrangian points are known as "Jupiter Trojan asteroids" or simply "Trojan asteroids".Minor planets in the and Sun–Neptune Lagrangian points are called Neptune trojans, with a lower-case "t", as "Trojan asteroid" was originally defined as a term for Lagrangian asteroids of Jupiter.

Asteroids are minor planets, especially of the inner Solar System. Larger asteroids have also been called planetoids. These terms have historically been applied to any astronomical object orbiting the Sun that did not resemble a planet-like disc and was not observed to have characteristics of an active comet such as a tail. As minor planets in the outer Solar System were discovered they were typically found to have volatile-rich surfaces similar to comets. As a result, they were often distinguished from objects found in the main asteroid belt.[1] In this article, the term "asteroid" refers to the minor planets of the inner Solar System including those co-orbital with Jupiter.
After years of research, Dr. Cunningham finally discovered who coined the word 'asteroid'. Although 'asteroid' has been attributed to the famous astronomer William Herschel, Cunningham found evidence that it was proposed by Greek expert Charles Burney, Jr., the son of a friend of Herschel. In 2014 he discovered a previously unrecognised allusion to the aurora borealis in Milton's "Paradise Lost".
"Asteroids" was immediately successful upon release. It displaced "Space Invaders" by popularity in the United States and became Atari's best selling arcade game of all time, with over 70,000 units sold. Atari earned an estimated $150 million in sales from the game, and arcade operators earned a further $500 million from coin drops. Atari had been in the process of manufacturing another vector game, "Lunar Lander", but demand for "Asteroids" was so high "that several hundred "Asteroids" games were shipped in "Lunar Lander" cabinets". "Asteroids" was so popular that some video arcade operators had to install large boxes to hold the number of coins spent by players.
Arthur C. Clarke coined the term in his novel "Rendezvous with Rama" (1972) where "Project Spaceguard" was the name of an early warning system created following a fictional catastrophic asteroid impact. This name was later adopted by a number of real life efforts to discover and study near-Earth objects. The name was used for the Survey "with the permission and encouragement of Clarke."
A 1992 US Congressional study produced a "Spaceguard Survey Report" which led to a mandate that NASA locate 90% of near-Earth asteroids larger than 1 km within 10 years. This is often referred to as the "Spaceguard Goal." A number of efforts which receive money through NASA are all considered to be working on the "Spaceguard Project."
In the United Kingdom the term "shrapnel" may be used for an inconvenient pocketful of loose change because of the association with a shrapnel shell and "wad" or "wedge" for a bundle of banknotes, with "tightwad" a derogatory term for someone who is reluctant to spend money. Similar to " shrapnel" the use of "washers" in Scotland denotes a quantity of low value coinage. Quantities of UK 1p and 2p coins may be referred to as "Copper", 5p, 10p, 20p, and 50p coins as "Silver" and £1 and £2 coins as "Bronze" due to their colour and apparent base metal type. "Brass" is northern English slang for any amount of money.
The in-universe term "flatlander" refers to any human born on Earth, in contrast to those who live on other planets or space habitats. The derogatory term was coined by Belters, whose space habitats are either enclosed, or located on large asteroids with visibly curving horizons. Whereas from any point on the surface of Earth the horizon looks "flat". 
The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The asteroid belt is also termed the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System such as near-Earth asteroids and trojan asteroids. About half the mass of the belt is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid belt is approximately 4% that of the Moon, or 22% that of Pluto, and roughly twice that of Pluto's moon Charon (whose diameter is 1200 km).
Asteroids in the and Sun–Mars Lagrangian points are sometimes called "Mars trojans," with a lower-case t, as "Trojan asteroid" was originally defined as a term for Lagrangian asteroids of Jupiter. They may also be called "Mars Lagrangian asteroids."
However, the term "lookism" was first coined in the 1970s within the fat acceptance movement. It was used in "The Washington Post" Magazine in 1978, which asserted that the term was coined by fat people who created the word to refer to "discrimination based on looks." The word appears in several major English language dictionaries. There is some overlap between the terms teratophobia, cacophobia and lookism.
A hypercane is a hypothetical class of extreme tropical cyclone that could form if ocean temperatures reached , which is warmer than the warmest ocean temperature ever recorded. Such an increase could be caused by a large asteroid or comet impact, a large supervolcanic eruption, or extensive global warming. There is some speculation that a series of hypercanes resulting from an impact by a large asteroid or comet contributed to the demise of the non-avian dinosaurs. The hypothesis was created by Kerry Emanuel of MIT, who also coined the term.
A stand-on system consists of a small laser array which is sent to the target asteroid. The system would be limited to small or medium size asteroids and would require detection relatively far in advance. For a short notice threat a stand-on system would be ineffective, due to the time required to build and send the system to the target. Additionally, a new system would be required for each target. In the short term a stand-on system could be affordable and feasible; however, in the long term a larger system able to deflect asteroids of all sizes is more practical.
