566 Stereoskopia
566 Stereoskopia is a large, outer main-belt asteroid orbiting the Sun. It was discovered on 28 May 1905 from Heidelberg by German astronomer Paul Götz. The discovery was made from Astrophotography, photographic plates with the use of a stereo-comparator that had been provided by Carl Pulfrich, a German physicist at the Carl Zeiss Company. The asteroid name is a reference to this device. This object is a member of the Cybele asteroid, Cybele group located beyond the core of the main belt. It is orbiting at a distance of with a orbital period, period of and an orbital eccentricity, eccentricity of 0.12. The orbital plane is inclined at an angle of 4.9° to the plane of the ecliptic. Light curve analysis based on Photometry (astronomy), photometric data collected during 2008 provide a rotation period of for this asteroid. It spans a girth of approximately 167 km and is classified as a carbonaceous C-type asteroid. See also * List of minor planet groups#Other groups out to ...

Paul Götz
Paul Götz (1883–1962) was a German astronomer and discoverer of 20 minor planets between 1903 and 1905. He did his Ph.D. dissertation in 1907 at the ''Landessternwarte Heidelberg-Königstuhl'' (Königstuhl Observatory, near Heidelberg) at the University of Heidelberg. At the time, the observatory at Heidelberg was a center for asteroid discovery under the direction of Max Wolf, and several past and future fellow Ph.D.s (Raymond Smith Dugan, Joseph Helffrich, Franz Kaiser, Karl Reinmuth, Emil Ernst, Alfred Bohrmann) made a number of asteroid discoveries. Thus the asteroid discoveries by "P. Gotz" at Heidelberg in this time frame are undoubtedly identified with the Paul Götz who got his Ph.D. in 1907.

Orbital Plane
The orbital plane of a revolving body is the geometric plane in which its orbit lies. Three non-collinear points in space suffice to determine an orbital plane. A common example would be the positions of the centers of a massive body (host) and of an orbiting celestial body at two different times/points of its orbit. The orbital plane is defined in relation to a reference plane by two parameters: inclination (''i'') and longitude of the ascending node (Ω). By definition, the reference plane for the Solar System is usually considered to be Earth's orbital plane, which defines the ecliptic, the circular path on the celestial sphere that the Sun appears to follow over the course of a year. In other cases, for instance a moon or artificial satellite orbiting another planet, it is convenient to define the inclination of the Moon's orbit as the angle between its orbital plane and the planet's equatorial plane.

Cybele Asteroids
The Cybele asteroids (also known as the "Cybeles") are a dynamical group of asteroids, named after the asteroid 65 Cybele. Considered by some as the last outpost of an extended asteroid belt, the group consists of just over 2000 members and a few collisional families. The Cybeles are in a 7:4 orbital resonance with Jupiter. Their orbit is defined by an osculating semi-major axis of 3.28 to 3.70 AU, with an eccentricity of less than 0.3, and an inclination less than 25°. The dynamical Cybele group is located adjacent to the outermost asteroid belt, beyond the Hecuba gap – the 2:1 resonant zone with Jupiter, where the Griqua asteroids are located – and inside the orbital region of the Hilda asteroids (3:2 resonance), which are themselves followed by the Jupiter trojans (1:1 resonance) further out. Description Three known asteroid families exist within the Cybele group: the Sylvia family (603), the Huberta family and the Ulla family (903). A potential fourth fami ...

List Of Minor Planet Groups
A minor-planet group is a population of minor planets that share broadly similar orbits. Members are generally unrelated to each other, unlike in an asteroid family, which often results from the break-up of a single asteroid. It is customary to name a group of asteroids after the first member of that group to be discovered, which is often the largest. Groups out to the orbit of Earth There are relatively few asteroids that orbit close to the Sun. Several of these groups are hypothetical at this point in time, with no members having yet been discovered; as such, the names they have been given are provisional. * Vulcanoid asteroids are hypothetical asteroids that orbit entirely within the orbit of Mercury (have an aphelion of less than 0.3874 AU). A few searches for vulcanoids have been conducted but none have been discovered so far. * ꞌAylóꞌchaxnim asteroids (previously named Vatira) are asteroids that orbit entirely within the orbit of Venus (have an aphelion of less ...

C-type Asteroid
C-type (carbonaceous) asteroids are the most common variety, forming around 75% of known asteroids. They are volatile-rich and distinguished by a very low albedo because their composition includes a large amount of carbon, in addition to rocks and minerals. Their density averages at about . They occur most frequently at the outer edge of the asteroid belt, 3.5 astronomical units (AU) from the Sun, where 80% of the asteroids are of this type, whereas only 40% of asteroids at 2 AU from the Sun are C-type. The proportion of C-types may actually be greater than this, because C-types are much darker (and therefore less detectable) than most other asteroid types except for D-types and others that are mostly at the extreme outer edge of the asteroid belt. Characteristics Asteroids of this class have spectra very similar to those of carbonaceous chondrite meteorites (types CI and CM). The latter are very close in chemical composition to the Sun and the primitive solar nebula minus h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon
Carbon () is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent In chemistry, the valence (US spelling) or valency (British spelling) of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules. Description The combining capacity, or affinity of an ...—its atom making four electrons available to form covalent bond, covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth's crust. Three Isotopes of carbon, isotopes occur naturally, Carbon-12, C and Carbon-13, C being stable, while Carbon-14, C is a radionuclide, decaying with a half-life of about 5,730 years.
