(434620) 2005 VD
(434620) 2005 VD, provisional designation , is a centaur and damocloid on a retrograde orbit from the outer Solar System, known for having the second most highly inclined orbit of any small Solar System body, behind . It was the most highly inclined known object between 2005 and 2013. The unusual object measures approximately in diameter. Description This minor planet was discovered on 1 November 2005, by astronomers of the Mount Lemmon Survey at Mount Lemmon Observatory near Tucson, Arizona. Precovery images have been found by the Sloan Digital Sky Survey (SDSS) from September 2005 and December 2001. Classification has a semi-major axis greater than Jupiter and almost crosses the orbit of Jupiter when near perihelion. JPL lists it as a current centaur. Both the Deep Ecliptic Survey (DES), and the Minor Planet Center (MPC) have listed it as a centaur (''qmin''=~5AU) at different epochs. The DES and MPC will list as a centaur again in 2032.

Mount Lemmon Survey
Mount Lemmon Survey (MLS) is a part of the Catalina Sky Survey with observatory code G96. MLS uses a cassegrain reflector telescope (with 10560x10560-pixel camera at the f/1.6 prime focus, for a five square degree field of view) operated by the Steward Observatory at Mount Lemmon Observatory, which is located at in the Santa Catalina Mountains northeast of Tucson, Arizona. It is currently one of the most prolific surveys worldwide, especially for discovering near-Earth objects. MLS ranks among the top discoverers on the Minor Planet Center's discovery chart with a total of more than 50,000 numbered minor planets. History Andrea Boattini and the survey accidentally rediscovered 206P/Barnard-Boattini, a lost comet, on 7 October 2008. The comet has made 20 revolutions since 1892 and passed within 0.3–0.4 AU of Jupiter in 1922, 1934 and 2005. This comet was also the first comet to be discovered by photographic means, by the American astronomer Edward Emerson Ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precovery
In astronomy, precovery (short for pre-discovery recovery) is the process of finding the image of a celestial object in images or photographic plates predating its discovery, typically for the purpose of calculating a more accurate orbit. This happens most often with minor planets, but sometimes a comet, a dwarf planet, a natural satellite, or a star is found in old archived images; even exoplanet precovery observations have been obtained. "Precovery" refers to a pre-discovery image; "recovery" refers to imaging of a body which was lost to our view (as behind the Sun), but is now visible again ''(also see lost minor planet and lost comet)''. Orbit determination requires measuring an object's position on multiple occasions. The longer the interval between observations, the more accurately the orbit can be calculated; however, for a newly discovered object, only a few days' or weeks' worth of measured positions may be available, sufficient only for a preliminary (imprecise) orbit ...

Damocloids
Damocloids are a List of minor-planet groups, class of minor planets such as 5335 Damocles and 1996 PW that have Halley-type comet, Halley-type or long-period highly eccentric orbits typical of periodic comets such as Halley's Comet, but without showing a coma (cometary), cometary coma or Comet tail, tail. David Jewitt defines a damocloid as an object with a Jupiter Tisserand invariant (TJ) of 2 or less, while Akimasa Nakamura defines this group with the following orbital elements: * Perihelion, q 8.0 AU, and Orbital eccentricity, e > 0.75, * or alternatively, Orbital inclination, ''i'' > 90Degree (angle), ° However, this definition that does not focus on Jupiter excludes objects such as , , and . Using the Tisserand's parameter with respect to Jupiter of 2 or less, there are currently 220 damocloid candidates . Of these objects, 189 have orbital observation arcs greater than 30 days providing reasonably decent orbits. Their average radius is eight kilometers assuming an A ...

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] |
Lowell Observatory
Lowell Observatory is an astronomical observatory in Flagstaff, Arizona, United States. Lowell Observatory was established in 1894, placing it among the oldest observatories in the United States, and was designated a National Historic Landmark in 1965. and In 2011, the Observatory was named one of "The World's 100 Most Important Places" by Time Magazine. It was at the Lowell Observatory that the dwarf planet Pluto was discovered in 1930 by Clyde Tombaugh. The observatory was founded by astronomer Percival Lowell of Boston's Lowell family and is overseen by a sole trustee, a position historically handed down through the family. The first trustee was Lowell's third cousin Guy Lowell (1916–1927). Percival's nephew Roger Putnam served from 1927 to 1967, followed by Roger's son Michael (1967–1987), Michael's brother William Lowell Putnam III (1987–2013), and current trustee W. Lowell Putnam.

Epoch (astronomy)
In astronomy, an epoch or reference epoch is a instant, moment in time used as a reference point for some time-varying astronomical quantity. It is useful for the celestial coordinates or orbital elements of a Astronomical object, celestial body, as they are subject to Perturbation (astronomy), perturbations and vary with time. These time-varying astronomical quantities might include, for example, the mean longitude or mean anomaly of a body, the node of its orbit relative to a reference plane, the direction of the apogee or Perihelion and aphelion, aphelion of its orbit, or the size of the major axis of its orbit. The main use of astronomical quantities specified in this way is to calculate other relevant parameters of motion, in order to predict future positions and velocities. The applied tools of the disciplines of celestial mechanics or its subfield orbital mechanics (for predicting orbital paths and positions for bodies in motion under the gravitational effects of other bodi ...

Deep Ecliptic Survey
The Deep Ecliptic Survey (DES) is a project to find Kuiper belt objects (KBOs), using the facilities of the National Optical Astronomy Observatory (NOAO). The principal investigator is Robert L. Millis. Since 1998 through the end of 2003, the survey covered 550 square degrees with sensitivity of 22.5, which means an estimated 50% of objects of this magnitude have been found. The survey has also established the mean Kuiper Belt plane and introduced new formal definitions of the dynamical classes of Kuiper belt objects. The remarkable first observations and/or discoveries include: * 28978 Ixion, large plutino * 19521 Chaos (cubewano) * , the first binary trans-Neptunian object (TNO) * , the first object with perihelion too far to be affected (scattered) by Neptune and a large semi-major axis * , remarkable for its semi-major axis of more than 500 AU and extreme eccentricity (0.96) taking the object from the inside of the Neptune's orbit to more than 1000 AU * , the first Ne ...

Perihelion
An apsis (; ) is the farthest or nearest point in the orbit of a planetary body about its primary body. The line of apsides (also called apse line, or major axis of the orbit) is the line connecting the two extreme values. Apsides pertaining to orbits around different bodies have distinct names to differentiate themselves from other apsides. Apsides pertaining to geocentric orbits, orbits around the Earth, are at the farthest point called the ''apogee'', and at the nearest point the ''perigee'', like with orbits of satellites and the Moon around Earth. Apsides pertaining to orbits around the Sun are named ''aphelion'' for the farthest and ''perihelion'' for the nearest point in a heliocentric orbit. Earth's two apsides are the farthest point, ''aphelion'', and the nearest point, ''perihelion'', of its orbit around the host Sun. The terms ''aphelion'' and ''perihelion'' apply in the same way to the orbits of Jupiter and the other planets, the comets, and the asteroids of ...
