Phaeo
322 Phaeo is an asteroid from the central regions of the asteroid belt, approximately in diameter. It was discovered on 27 November 1891, by French astronomer Alphonse Borrelly at the Marseille Observatory in southern France.

Phaeo Family
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. General properties Large prominent families contain several hundred recognized asteroids (and many more smaller objects which may be either not-yet-analyzed, or not-yet-discovered). Small, compact families may have only about ten identified members. About 33% to 35% of asteroids in the main belt are family members. There are about 20 to 30 reliably recognized families, with several tens of less certain groupings. Most asteroid families are found in the main asteroid belt, although several family-like groups such as the Pallas family, Hungaria family, and the Phocaea famil ...

Hyades (mythology)
In Greek mythology, the Hyades (; , popularly "rain-makers" or "the rainy ones"; from , but probably from ) are a sisterhood of nymphs that bring rain. Family The Hyades were daughters of Atlas (by either Pleione or Aethra, one of the Oceanids) and sisters of Hyas in most tellings, although one version gives their parents as Hyas and Boeotia.Hyginus, ''Fabulae'' 192Hyginus, ''De astronomia'' 2.21 The Hyades are sisters to the Pleiades and the Hesperides. Names Their number varies from three in the earliest sources to fifteen in the late ones. The names are also variable, according to the mythographer, and include: Additionally, Thyone and Prodice were supposed to be daughters of Hyas by Aethra, and have been added to the group of stars. Mythology The main myth concerning them is envisioned to account for their collective name and to provide an etiology for their weepy raininess: Hyas was killed in a hunting accident and the Hyades wept from their grief.

Alphonse Borrelly
Alphonse Louis Nicolas Borrelly (December 8, 1842 – February 28, 1926) was a French astronomer born in Roquemaure, Gard. He joined the Marseille Observatory in 1864. In the course of his career, he discovered a number of asteroids and comets, including the periodic comet 19P/Borrelly. He also discovered five NGC objects, all galaxies. The French Academy of Sciences awarded him the Prix Valz for 1903 and the Prix Lalande for 1909. The asteroid 1539 Borrelly was named in his honor. In 1913, he received the Prix Jules Janssen, the highest award of the Société astronomique de France, the French astronomical society. Discoveries Comets discovered or co-discovered The following is an incomplete list of comets discovered or co-discovered by Borrelly: * C/1873 Q1 (Borrelly) * C/1877 C1 (Borrelly) * C/1877 G2 (Swift-Borrelly-Block) * C/1889 X1 (Borrelly) * C/1900 O1 (Borrelly–Brooks) * 19P/Borrelly Comet Borrelly or Borrelly's Comet (official designation: 19P/Borrell ...

Greek Mythology
Greek mythology is the body of myths originally told by the Ancient Greece, ancient Greeks, and a genre of ancient Greek folklore, today absorbed alongside Roman mythology into the broader designation of classical mythology. These stories concern the ancient Greek religion's view of the Cosmogony, origin and Cosmology#Metaphysical cosmology, nature of the world; the lives and activities of List of Greek deities, deities, Greek hero cult, heroes, and List of Greek mythological creatures, mythological creatures; and the origins and significance of the ancient Greeks' cult (religious practice), cult and ritual practices. Modern scholars study the myths to shed light on the religious and political institutions of ancient Greece, and to better understand the nature of mythmaking itself. The Greek myths were initially propagated in an oral tradition, oral-poetic tradition most likely by Minoan civilization, Minoan and Mycenaean Greece, Mycenaean singers starting in the 18th century&n ...

X-type Asteroids (Tholen)
The X-group of asteroids collects together several types with similar spectra, but probably quite different compositions. Tholen classification In the Tholen classification, the X-group consists of the following types: * E-type – with high albedo (> 0.30), composed of enstatite, forsterite and feldspar. They are found in the inner main belt. * M-type – the largest grouping, intermediate albedo, "metallic", composed of iron and nickel, thought to be the progenitors of nickel–iron meteorites. They are found around 3.0 AU and in the Hungaria region (innermost main-belt). * P-type – low albedos (< 0.10) with featureless red spectra; presumably composed of carbonaceous chondrites, and found in the outer main-belt and the Jupiter trojan region. Since in this scheme, the albedo is crucial in discriminating between the above types, some objects for which albedo information was not available were assigned an X-type. An example of this is 50 Virginia. SMASS clas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jet Propulsion Laboratory
The Jet Propulsion Laboratory (JPL) is a Federally funded research and development centers, federally funded research and development center (FFRDC) in La Cañada Flintridge, California, Crescenta Valley, United States. Founded in 1936 by California Institute of Technology (Caltech) researchers, the laboratory is now owned and sponsored by NASA and administered and managed by Caltech. The primary function of the laboratory is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating the NASA Deep Space Network (DSN). Among the major active projects at the laboratory, some are the Mars 2020 mission, which includes the ''Perseverance (rover), Perseverance'' rover; the Mars Science Laboratory mission, including the ''Curiosity (rover), Curiosity'' rover; the ''Mars Reconnaissance Orbiter''; the ''Juno (spacecraft), Juno'' spacecraft orbiting Jupiter; the ''Soil Moisture Active P ...

308 Polyxo
308 Polyxo is a main-belt asteroid that was discovered by Alphonse Borrelly on 31 March 1891, in Marseille. It is orbiting the Sun at a distance of with a low orbital eccentricity (ovalness) of 0.04 and a period of . The orbital plane is tilted at an angle of 4.36° to the plane of the ecliptic. 308 Polyxo is classified as a rare T-type asteroid, with a spectrum that bears some similarity to the Tagish Lake meteorite. A spectral feature at a wavelength of suggests aqueous alteration of some surface materials. Photometric measurements reported in 1983 give a rotation period of 12.03 hours and a brightness variation of 0.20 in magnitude. The adaptive optics instrument at the W. M. Keck Observatory shows an oblate object with a diameter of 130 km. The size ratio between the major and minor axes is 1.26 ± 0.11. Light curves for this object suggests it has a very irregular shape. Stellar occultation events were observed for this asteroid during 2000 and 2004. The resultin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
217 Eudora
217 Eudora is a large Main belt asteroid. It was discovered by French (Corsican) astronomer Jérôme Eugène Coggia on August 30, 1880, in Marseille, France. It was his fourth asteroid discovery and is probably named after Eudora, one of the Hyades in Greek mythology.Lutz D. Schmadel, ''Dictionary of Minor Planet Names'', p. 51. Springer, . It probably has a composition similar to carbonaceous chondrites. In 2007, a study showed it rotates every 25.253 ± 0.003 hours, based on lightcurve data. A light curve generated from photometric observations at Pulkovo Observatory, give a matching rotation period of 25.253 ± 0.002 hours and a brightness variation of 0.22 ± 0.04 in magnitude Magnitude may refer to: Mathematics *Euclidean vector, a quantity defined by both its magnitude and its direction *Magnitude (mathematics), the relative size of an object *Norm (mathematics), a term for the size or length of a vector *Order of ....
