List Of Proper Names Of Exoplanets
Proper names for planets outside of the Solar System – known as exoplanets – are chosen by the International Astronomical Union (IAU) through public naming contests known as NameExoWorlds. Naming The IAU's names for exoplanets – and on most occasions their Planet-hosting stars, host stars – are chosen by the Executive Committee Working Group (ECWG) on Public Naming of Planets and Planetary Satellites, a group working parallel with the IAU Working Group on Star Names, Working Group on Star Names (WGSN). List of proper names of stars, Proper names of stars chosen by the ECWG are explicitly recognised by the WGSN. The ECWG's rules for naming exoplanets are identical to those adopted by the Minor Planet Center for minor planets. Names are a single word consisting of sixteen characters or less, pronounceable in some language, Profanity, non-offensive, and not identical to existing proper names of astronomical objects.

Arcas
In Greek mythology, Arcas (; Ancient Greek: Ἀρκάς) was a hunter who became king of Arcadia. He was remembered for having taught people the arts of weaving and baking bread and for spreading agriculture to Arcadia. Family Arcas was the son of Zeus and Callisto. In other accounts, his birth mother was called Megisto, daughter of Ceteus, son of Lycaon, or else Themisto, daughter of Inachus. Arcas was married to either Laodamia ( Leaneira), daughter of Amyclas of Sparta; Meganeira, daughter of Crocon; the nymph Chrysopeleia; or the Dryad Erato. He also left a number of children, including the sons Azan, Apheidas, Elatus, and Triphylus, an illegitimate son Autolaus and at least two daughters, Hyperippe and Diomeneia. Arcas's other sons were Erymanthus and Pelasgus. Mythology Callisto was a nymph in the retinue of the goddess Artemis, or in some sources the daughter of King Lycaon. As she would not be with anyone but Artemis, Zeus cunningly disguise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
18 Delphini
18 Delphini, also named Musica , is a single star in the constellation of Delphinus of the low northern hemisphere. It has a Sun-like golden hue and is faintly visible to the naked eye with an apparent visual magnitude of 5.506. The star is located at a distance of approximately 245 light-years from the Sun based on parallax, and it is drifting further away with a radial velocity of +4 km/s. An object believed to be an extrasolar planet (designated 18 Delphini b or Arion) orbits the star. Nomenclature 18 Delphini is the star's Flamsteed designation, abbreviated 18 Del. Following its discovery the planet was designated 18 Delphini b. As part of the NameExoWorlds program by the International Astronomical Union, in 2015 the name Musica, Latin for 'music', was selected for this star by Tokushima Prefectural Jonan High School Science Club of Japan. The planet was given the name Arion, after a genius of poetry and music in ancient Greece. According to legend, his life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arion
Arion (; ) was a kitharode in ancient Greece, a Dionysiac poet credited with inventing the dithyramb. The islanders of Lesbos claimed him as their native son, but Arion found a patron in Periander, tyrant of Corinth. Although notable for his musical inventions, Arion is chiefly remembered for the fantastic myth of his kidnapping by pirates and miraculous rescue by dolphins, a folktale motif. Origins Arion was a native of Methymna in Lesbos, and, according to some mythological accounts, a son of Cyclon or of Poseidon and the nymph Oncaea. All traditions about him agree in describing him as a contemporary and friend of Periander, tyrant of Corinth. He appears to have spent a great part of his life at the court of Periander, but respecting his life and his poetical or musical productions, scarcely anything is known beyond the story of his escape from the sailors with whom he sailed from Sicily to Corinth. The dithyramb Arion is often called the inventor of the dithyrambic po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
18 Delphini B
18 Delphini b (abbreviated 18 Del b), formally named Arion , is an extrasolar planet approximately 249 light-years away in the constellation of Delphinus. The 993-day period planet orbits the yellow giant star 18 Delphini. A very massive and dense planet with a minimum mass of , it was discovered on February 19, 2008, by Bun'ei Sato. In July 2014, the International Astronomical Union launched NameExoWorlds, a process for giving proper names to certain exoplanets and their host stars. The process involved public nomination and voting for the new names. In December 2015, the IAU announced the name Arion for this planet. The winning name was submitted by the Tokushima Prefectural Jonan High School Science Club of Japan. Arion was a genius of poetry and music in ancient Greece. According to legend, his life was saved at sea by dolphins after attracting their attention by the playing of his kithara ('Delphinus' is Latin for 'dolphin').

14 Andromedae
14 Andromedae, abbreviated 14 And, also named Veritate , is a single, orange-hued giant star situated 248 light-years away in the northern constellation of Andromeda. It is dimly visible to the naked eye with an apparent visual magnitude of 5.22. The star is moving closer to the Earth with a heliocentric radial velocity of −60 km/s. In 2008 an extrasolar planet (designated 14 Andromedae b, later named ''Spe'') was discovered to be orbiting the star. This is a red clump giant with a stellar classification of K0 III, a star that has past the first-giant branch and is now on the horizontal branch, generating energy through helium fusion at its core. The star has expanded to 12.7 times the Sun's radius and is radiating 58 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,483 K. Its exact mass and age are still uncertain. Nomenclature 14 Andromedae is the star's Flamsteed designation. Following its discovery the pl ...

Effective Temperature
The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation. Effective temperature is often used as an estimate of a body's surface temperature when the body's emissivity curve (as a function of wavelength) is not known. When the star's or planet's net emissivity in the relevant wavelength band is less than unity (less than that of a black body), the actual temperature of the body will be higher than the effective temperature. The net emissivity may be low due to surface or atmospheric properties, such as the greenhouse effect. Star The effective temperature of a star is the temperature of a black body with the same luminosity per ''surface area'' () as the star and is defined according to the Stefan–Boltzmann law . Notice that the total ( bolometric) luminosity of a star is then , where is the stellar radius. The definition of the stellar radius is obviously not ...

Semi-major And Semi-minor Axes
In geometry, the major axis of an ellipse is its longest diameter: a line segment that runs through the center and both foci, with ends at the two most widely separated points of the perimeter. The semi-major axis (major semiaxis) is the longest semidiameter or one half of the major axis, and thus runs from the centre, through a focus, and to the perimeter. The semi-minor axis (minor semiaxis) of an ellipse or hyperbola is a line segment that is at right angles with the semi-major axis and has one end at the center of the conic section. For the special case of a circle, the lengths of the semi-axes are both equal to the radius of the circle. The length of the semi-major axis of an ellipse is related to the semi-minor axis's length through the eccentricity and the semi-latus rectum \ell, as follows: The semi-major axis of a hyperbola is, depending on the convention, plus or minus one half of the distance between the two branches. Thus it is the distance from the cente ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orbital Period
The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object. In astronomy, it usually applies to planets or asteroids orbiting the Sun, moons orbiting planets, exoplanets orbiting other stars, or binary stars. It may also refer to the time it takes a satellite orbiting a planet or moon to complete one orbit. For celestial objects in general, the orbital period is determined by a 360° revolution of one body around its primary, ''e.g.'' Earth around the Sun. Periods in astronomy are expressed in units of time, usually hours, days, or years. Its reciprocal is the orbital frequency, a kind of revolution frequency, in units of hertz. Small body orbiting a central body According to Kepler's Third Law, the orbital period ''T'' of two point masses orbiting each other in a circular or elliptic orbit is: :T = 2\pi\sqrt where: * ''a'' is the orbit's semi-major axis * ''G'' is the gravitationa ...
