29 Amphitrite
Amphitrite ( minor planet designation: 29 Amphitrite) is one of the largest S-type asteroids, approximately in diameter, and probably fifth largest after Eunomia, Juno, Iris and Herculina. Discovery Amphitrite was discovered by Albert Marth on 1 March 1854, at the private South Villa Observatory, in Regent's Park, London. It was Marth's only asteroid discovery. Its name was chosen by George Bishop, the owner of the observatory, who named it after Amphitrite, a sea goddess in Greek mythology. Characteristics Amphitrite's orbit is less eccentric and inclined than those of its larger cousins; indeed, it is the most circular of any asteroid discovered up to that point. As a consequence, it never becomes as bright as Iris or Hebe, especially as it is much further from the Sun than those asteroids. It can reach magnitudes of around +8.6 at a favorable opposition, but usually is around the binocular limit of +9.5. In 2007, James Baer and Steven R. Chesley estimated Amphitr ...

Amphitrite Symbol (bold)
In ancient Greek mythology, Amphitrite (; grc-gre, Ἀμφιτρίτη, Amphitrítē) was the goddess of the sea, the queen of the sea, and the wife of Poseidon. She was a daughter of Nereus and Doris (or Oceanus and Tethys).Roman, L., & Roman, M. (2010). Under the influence of the Olympian pantheon, she became the consort of Poseidon and was later used as a symbolic representation of the sea. Her Roman counterpart is Salacia, a comparatively minor figure, and the goddess of saltwater. Mythology Amphitrite was a daughter of Nereus and Doris (and thus a Nereid), according to Hesiod's ''Theogony'', but of Oceanus and Tethys (and thus an Oceanid), according to the '' Bibliotheca'', which actually lists her among both the Nereids and the Oceanids. Others called her the personification of the sea itself (saltwater). Marriage to Poseidon When Poseidon desired to marry her, Amphitrite, wanting to protect "her virginity", fled to the Atlas mountains. Poseidon sent m ...

Regent's Park
Regent's Park (officially The Regent's Park) is one of the Royal Parks of London. It occupies of high ground in north-west Inner London, administratively split between the City of Westminster and the Borough of Camden (and historically between Marylebone and Saint Pancras parishes). In addition to its large central parkland and ornamental lake, it contains various structures and organizations both public and private, generally on its periphery, including Regent's University and London Zoo. What is now Regent's Park came into possession of the Crown upon the dissolution of the monasteries in the 1500s, and was used for hunting and tenant farming. In the 1810s, the Prince Regent proposed turning it into a pleasure garden. The park was designed by John Nash and James and Decimus Burton. Its construction was financed privately by James Burton after the Crown Estate rescinded its pledge to do so, and included development on the periphery of townhouses and expensive terrace ...

Mauna Kea Observatories
The Mauna Kea Observatories (MKO) are a group of independent astronomical research facilities and large telescope observatories that are located at the summit of Mauna Kea on the Big Island of Hawaiʻi, United States. The facilities are located in a 525-acre (212 ha) special land use zone known as the "Astronomy Precinct", which is located within the 11,228-acre (4,544 ha) Mauna Kea Science Reserve. The Astronomy Precinct was established in 1967 and is located on land protected by the Historical Preservation Act for its significance to Hawaiian culture. The presence and continued construction of telescopes is highly controversial due to Mauna Kea's centrality in native Hawaiian religion and culture, as well as for a variety of environmental reasons. The location is near ideal because of its dark skies from lack of light pollution, good astronomical seeing, low humidity, high elevation of , position above most of the water vapor in the atmosphere, clean air, good wea ...

UH88
The University of Hawai'i 88-inch (2.24-meter) telescope—called UH88, UH2.2, or simply 88 by members of the local astronomical community—is situated at the Mauna Kea Observatories and operated by the University's Institute for Astronomy. It was constructed in 1968, and entered service in 1970, at which point it was known as "The Mauna Kea Observatory". It became one of the first professional telescopes to be controlled by a computer. The telescope was built with funding from NASA, to support Solar System missions, and is controlled by the University of Hawai'i. The success of the telescope helped demonstrate the value of Mauna Kea for astronomical observations. On December 4, 1984 it became the first telescope to make optical closure phase measurements on an astronomical source using an aperture mask. UH88 is a Cassegrain reflector tube telescope with an f/10 focal ratio, supported by a large open fork equatorial mount. It was the last telescope on Mauna Kea to use a tub ...

Natural Satellite
A natural satellite is, in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite). Natural satellites are often colloquially referred to as ''moons'', a derivation from the Moon of Earth. In the Solar System, there are six planetary satellite systems containing 209 known natural satellites altogether. Seven objects commonly considered dwarf planets by astronomers are also known to have natural satellites: , Pluto, Haumea, , Makemake, , and Eris. , there are 442 other minor planets known to have natural satellites. A planet usually has at least around 10,000 times the mass of any natural satellites that orbit it, with a correspondingly much larger diameter. The Earth–Moon system is a unique exception in the Solar System; at 3,474 kilometres (2,158 miles) across, the Moon is 0.273 times the diameter of Earth and about of its mass. The next largest ratios are the Neptune– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binoculars
Binoculars or field glasses are two refracting telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most binoculars are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal-mounted military models. Unlike a (monocular) telescope, binoculars give users a stereopsis, three-dimensional image: each eyepiece presents a slightly different image to each of the viewer's eyes and the parallax allows the visual cortex to generate an depth perception, impression of depth. Optical designs Galilean Almost from the invention of the telescope in the 17th century the advantages of mounting two of them side by side for binocular vision seems to have been explored. Most early binoculars used Galilean telescope, Galilean optics; that is, they used a convex lens, convex objective (optics), objective and a concave lens, concave eyepiece, eyep ...

6 Hebe
Hebe (minor planet designation: 6 Hebe) is a large main-belt asteroid, containing around 0.5% of the mass of the belt. However, due to its apparently high bulk density (greater than that of the Moon or even Mars), Hebe does not rank among the top twenty asteroids by volume. This high bulk density suggests an extremely solid body that has not been impacted by collisions, which is not typical of asteroids of its size – they tend to be loosely-bound rubble piles. In brightness, Hebe is the fifth-brightest object in the asteroid belt after Vesta, Ceres, Iris, and Pallas. It has a mean opposition magnitude of +8.3, about equal to the mean brightness of Titan, and can reach +7.5 at an opposition near perihelion. Hebe may be the parent body of the H chondrite meteorites, which account for about 40% of all meteorites striking Earth. History Hebe was discovered on 1 July 1847 by Karl Ludwig Hencke, the sixth asteroid discovered. It was the second and final asteroid discovery by Henc ...
