42355 Typhon
42355 Typhon (; Minor planet provisional designation, provisional designation ) is a scattered disc object that was discovered on February 5, 2002, by the Near-Earth Asteroid Tracking, NEAT program. It measures in diameter, and is named after Typhon, a monster in Greek mythology. Typhon is the first known binary Centaur (minor planet), centaur, using an extended definition of a Centaur (minor planet), centaur as an object on a non-resonant (unstable) orbit with the perihelion inside the orbit of Neptune. Planetary symbols are no longer much used in astronomy, so Typhon never received a symbol in the astronomical literature. There is no standard symbol for Typhon used by astrologers either. A hurricane symbol () has been used, which might be identified with . Physical properties Typhon has a BR taxonomic class, with a blue surface. It has a resulting B–R magnitude of 1.274. Based on a conventional magnitude-to-diameter conversion, the body measures 162 km in diameter, with an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhon Symbol (bold)
Typhon (; , ), also Typhoeus (; ), Typhaon () or Typhos (), was a monstrous serpentine giant and one of the deadliest creatures in Greek mythology. According to Hesiod, Typhon was the son of Gaia and Tartarus. However, one source has Typhon as the son of Hera alone, while another makes Typhon the offspring of Cronus. Typhon and his mate Echidna (mythology), Echidna were the progenitors of many famous monsters. Typhon attempted to overthrow Zeus for the supremacy of the cosmos. The two fought a cataclysmic battle, which Zeus finally won with the aid of his thunderbolts. Defeated, Typhon was cast into Tartarus, or buried underneath Mount Etna, or in later accounts, the island of Ischia. Typhon mythology is part of the Greek succession myth, which explained how Zeus came to rule the gods. Typhon's story is also connected with that of Python (mythology), Python (the serpent killed by Apollo), and both stories probably derived from several Near Eastern antecedents. Typhon was (from ) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Centaurs (small Solar System Bodies)
A centaur ( ; ; ), occasionally hippocentaur, also called Ixionidae (), is a creature from Greek mythology with the upper body of a human and the lower body and legs of a horse that was said to live in the mountains of Thessaly. In one version of the myth, the centaurs were named after Centaurus, and, through his brother Lapithes, were kin to the legendary tribe of the Lapiths. Centaurs are thought of in many Greek myths as being as wild as untamed horses, and were said to have inhabited the region of Magnesia and Mount Pelion in Thessaly, the Foloi oak forest in Elis, and the Malean peninsula in southern Laconia. Centaurs are subsequently featured in Roman mythology, and were familiar figures in the medieval bestiary. They remain a staple of modern fantastic literature. Etymology The Greek word ''kentauros'' is generally regarded as being of obscure origin. The etymology from ''ken'' + ''tauros'', 'piercing bull', was a euhemerist suggestion in Palaephatus' rationalizing te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asteroid Moon
A minor-planet moon is an astronomical object that orbits a minor planet as its natural satellite. , there are 457 minor planets known or suspected to have moons. Discoveries of minor-planet moons (and binary objects, in general) are important because the determination of their orbits provides estimates on the mass and density of the primary, allowing insights into their physical properties that are generally not otherwise accessible. Several of the moons are quite large compared to their primaries: 90 Antiope, Mors–Somnus and Sila–Nunam (95%), Patroclus–Menoetius, Altjira and Lempo–Hiisi (90%, with Lempo–Paha at 50%). The largest known minor-planet moon in ''absolute'' size is Pluto's largest moon Charon, which itself has about half the diameter of Pluto. There are also several known ring systems around distant objects (see: '' Rings of Chariklo'' and ''Chiron''). Terminology In addition to the terms ''satellite'' and ''moon'', the term "binary" (binary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echidna (mythology)
In Greek mythology, Echidna (; , ) was a monster, half-woman and half-snake, who lived alone in a cave. She was the mate of the fearsome monster Typhon and was the mother of many of the most famous monsters of Greek myth. Genealogy Echidna's family tree varies by author. The oldest genealogy relating to Echidna, Hesiod's ''Theogony'' (c. 8th – 7th century BC), is unclear on several points. According to Hesiod, Echidna was born to a "she" who was probably meant by Hesiod to be the sea goddess Ceto, making Echidna's likely father the sea god Phorcys; however the "she" might instead refer to the Oceanids, Oceanid Callirhoe (Oceanid), Callirhoe, which would make Medusa's offspring Chrysaor the father of Echidna. The mythographer Pherecydes of Athens (5th century BC) has Echidna as the daughter of Phorcys, without naming a mother. Other authors give Echidna other parents. According to the geographer Pausanias (geographer), Pausanias (2nd century AD), Epimenides (7th or 6th century B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rotational Period
In astronomy, the rotation period or spin period of a celestial object (e.g., star, planet, moon, asteroid) has two definitions. The first one corresponds to the ''sidereal rotation period'' (or ''sidereal day''), i.e., the time that the object takes to complete a full rotation around its axis relative to the background stars ( inertial space). The other type of commonly used "rotation period" is the object's '' synodic rotation period'' (or ''solar day''), which may differ, by a fraction of a rotation or more than one rotation, to accommodate the portion of the object's orbital period around a star or another body during one day. Measuring rotation For solid objects, such as rocky planets and asteroids, the rotation period is a single value. For gaseous or fluid bodies, such as stars and giant planets, the period of rotation varies from the object's equator to its pole due to a phenomenon called differential rotation. Typically, the stated rotation period for a giant planet (s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lightcurve
In astronomy, a light curve is a graph (discrete mathematics), graph of the Radiance, light intensity of a celestial object or region as a function of time, typically with the magnitude (astronomy), magnitude of light received on the ''y''-axis and with time on the ''x''-axis. The light is usually in a particular frequency interval or frequency band, band. Light curves can be periodic, as in the case of eclipsing binary, eclipsing binaries, Cepheid variables, other periodic variables, and Methods of detecting extrasolar planets#Transit photometry, transiting extrasolar planets; or aperiodic, like the light curve of a nova, cataclysmic variable star, supernova, gravitational microlensing, microlensing event, or binary as observed during occultation events. The study of a light curve and other observations can yield considerable information about the physical process that produces such a light curve, or constrain the physical theories about it.
