12373 Lancearmstrong
12373 Lancearmstrong, provisional designation , is a bright Vesta family, Vestian asteroid from the inner regions of the asteroid belt, approximately in diameter. It was discovered on 15 May 1994, by American astronomer and software engineer Charles de Saint-Aignan after examining films taken at Palomar Observatory, California, and named after American cyclist Lance Armstrong. Orbital and physical characteristics The asteroid orbits the Sun in the Kirkwood gap, inner main-belt at a distance of 2.2–2.7 Astronomical unit, AU once every 3 years and 10 months (1,401 days). Its orbit has an orbital eccentricity, eccentricity of 0.11 and an orbital inclination, inclination of 7Degree (angle), ° with respect to the ecliptic. The body's observation arc begins in 1994, as no precoveries were taken prior to its discovery. Based on an absolute Magnitude (astronomy), magnitude of 14.2 and an assumed astronomical albedo, albedo of 0.20, which is typical for bodies with a S-type a ...

Charles De Saint-Aignan
Charles P. de Saint-Aignan (born 16 February 1977, Paris) is an American software engineer who works for IBM on the IBM Watson project. He graduated from St. Paul's School (Concord, New Hampshire), in 1995, followed by Brown University (Providence, Rhode Island), in 1999. In 1994, de Saint-Aignan worked for Ted Bowell at Lowell Observatory, where he discovered a number of asteroids. He named his first discovery, 8710 Hawley, after Walter N. Hawley, who was his high school physics and astronomy teacher. The minor planet 5995 Saint-Aignan was named in de Saint-Aignan's honor on the occasion of his 20th birthday.

Precoveries
In astronomy, precovery (short for pre-discovery recovery) is the process of finding the image of an 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 calculatio ...

This is a list of minor planets which have been officially named by the Working Group Small Body Nomenclature (WGSBN) of the International Astronomical Union (IAU). The list consists of partial pages, each covering a number range of 1,000 bodies citing the source after each minor planet was named for. An overview of all existing partial pages is given in section . Among the hundreds of thousands of numbered minor planets only a small fraction have received a name so far. , there are 23,542 named minor planets out of a total of more than 600,000 numbered ones . Most of these bodies are named for people, in particular astronomers, as well as figures from mythology and fiction. Many minor planets are also named after places such cities, towns, and villages, mountains and volcanoes; after rivers, observatories, as well as organizations, clubs and astronomical societies. Some are named after animals and plants. A few minor planets are named after exotic entities such as supercompute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Exceptional Asteroids
The following is a collection of lists of asteroids of the Solar System that are exceptional in some way, such as their size or orbit. For the purposes of this article, "asteroid" refers to minor planets out to the orbit of Neptune, and includes the dwarf planet 1 Ceres, the Jupiter trojans and the centaurs, but not trans-Neptunian objects (objects in the Kuiper belt, scattered disc or inner Oort cloud). For a complete list of minor planets in numerical order, see List of minor planets. Background Asteroids are given minor planet numbers, but not all minor planets are asteroids. Minor planet numbers are also given to objects of the Kuiper belt, which is similar to the asteroid belt but farther out (around 30–60 AU), whereas asteroids are mostly between 2–3 AU from the Sun and at the orbit of Jupiter 5 AU from the Sun. Also, comets are not typically included under minor planet numbers, and have their own naming conventions. Asteroids are given a uniq ...

Minor Planet
According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. Before 2006, the IAU officially used the term ''minor planet'', but that year's meeting reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006.

Rotation Period
The rotation period of a celestial object (e.g., star, gas giant, planet, moon, asteroid) may refer to its sidereal rotation period, i.e. the time that the object takes to complete a single revolution around its axis of rotation relative to the background stars, measured in sidereal time. The other type of commonly used rotation period is the object's synodic rotation period (or ''solar day''), measured in solar time, which may differ by a fraction of a rotation or more than one rotation to accommodate the portion of the object's orbital period 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 gas giants, 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 gas giant (such as Jupiter, Saturn, Uranus, Neptune) is its internal rotation period, as d ...

NEOWISE
Wide-field Infrared Survey Explorer (WISE, observatory code C51, Explorer 92 and SMEX-6) is a NASA infrared astronomy space telescope in the Explorers Program. It was launched in December 2009, and placed in hibernation mode in February 2011, before being re-activated in 2013 and renamed the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE). WISE discovered thousands of minor planets and numerous star clusters. Its observations also supported the discovery of the first Y-type brown dwarf and Earth trojan asteroid. WISE performed an all-sky astronomical survey with images in 3.4, 4.6, 12 and 22 μm wavelength range bands, over ten months using a diameter infrared telescope in Earth orbit. After its solid hydrogen coolant depleted, a four-month mission extension called NEOWISE was conducted to search for near-Earth objects (NEO) such as comets and asteroids using its remaining capability. The WISE All-Sky (WISEA) data, including processed images, source cata ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
