S-type asteroid - S-type asteroid Apxoximately 17% of all known asteroids are of an S-type, a relatively bright (albedo 0.10 to 0.22) asteroid, consisting of metallic nickel-iron mixed with iron- and magnesium-silicates..
V-type asteroid - V-type asteroid The V-type asteroid is very similar to the more common S-type, as it is also made up of stony irons and ordinary chondrites. The only significant difference between this rarer form of asteroid is that it contains more pyroxene than the more commonly found S-type. It is thought that most or all V-type asteroids originated as fragments from the crust of the asteroid 4 Vesta, possibly blasted out by a single very large impact at some point in Vesta's history..
Asteroid - Asteroid An asteroid (or minor planet) is a small, solid object in our Solar System, orbiting the Sun. Asteroids are much smaller than planets. They are believed to be remnants of the protoplanetary disc; which were not incorporated into planets during the system's formation. The vast majority of the asteroids are within the asteroid belt, with elliptical orbits between that of Mars and Jupiter. Some asteroids have moonss. The exact definition of an asteroid is unclear. Minor planets whose semi-major axes are beyond that of Jupiter, and which are primarly made of ice are either comets, Centaurss, or Trans-Neptunian objects. Meteoroids are solid objects in interplanetary space that are substantially smaller than asteroids (much less than 1 km in diameter). Meteoroids are typically boulder-sized or smaller..
Gundam Seed Episodes 1-5 - ship docks in Heliopolis, carrying ace mobile armor pilot Mwu La Fllaga and the five test pilots for the new secret Gundam mobile suits. The captain doesn't think that ZAFT will attack one of Aube's neutral colonies, and Mwu is sick of hearing that. In space, a Nazca class Vesalius and the Laurasia class ship Gamow hides behind an asteroid. On the Vesalius, a masked man named Raww Le Klueze discusses with the captain intelligence on the Gundams. Smaller vessels launch from both ships and head for Heliopolis. Kira, Miriallia and Tolle leave to visit Professor Kato and run into a girl named Fllay Allster, who is talking to two other girls about receiving a letter from Kira's friend Ssigh Argyle. A military officer named Natarle Badgiruel passes them and gets.

Dyson sphere - Maker by Olaf Stapledon. The original proposal by Dyson did not go into much detail about how a Dyson sphere would be constructed, focusing instead on the more fundamental issue of how an advanced civilization could expand its energy production to the maximum possible for a given solar system. Such a civilization would be classified as a Type II civilization under the Kardashev classification scheme developed by the astronomer Nikolai Kardashev. A star contained within a Dyson sphere would not be directly visible to the outside universe, but the Dyson sphere itself would radiate an equivalent amount of energy in the form of infrared light due to solar heating from within. In addition, since Dyson spheres are composed of solid matter, it would radiate a black body spectrum. Dyson proposed that.
Deimos (moon) - undiscovered ones undoubtedly exist around the outer planets. It was discovered on August 10 1877 by Asaph Hall. Deimos is composed of carbon-rich rock, much like C-type (carbonaceous chondrite) asteroids, and ice. It is heavily cratered. It is probably an asteroid that was perturbed by Jupiter into an orbit that allowed it to be captured by Mars, though this theory is still in some dispute. Like most bodies of its size, Deimos is highly nonspherical with dimensions of 15×12.2×11 km. An image of Deimos taken by the Viking 1 orbiter. See Also: List of features on Phobos and Deimos\n.

Palisa, 1884 243 Ida is an asteroid that was imaged by the Galileo probe on August 28, 1993. The probe discovered that Ida had a small moon, an asteroid dubbed Dactyl, only 1.4 km in diameter; this was the first asteroid moon to be discovered. Some researchers believe that Dactyl formed from debris ejected from Ida by cratering, while others suggest that Ida and Dactyl formed as a pair a billion or more years ago when Ida's parent body was disrupted. Both of these.

However, its unusual orbit was not determined until 1997 by Paul Wiegert and Kimmo Innanen, working at York University in Canada, and Seppo Mikkola, working at the University of Turku in Finland. The Dalriada Celtic Heritage Trust inform us the Cruithne.
4 Vesta - 4 Vesta 4 Vesta Orbital characteristics Orbit type Main belt Semimajor axis 2.362 AU Eccentricity 0.0895 Orbital period 3.63 Years Inclination 7.14° Physical characteristics Diameter 525 km Mass 3.0×1020 kg Density 3.3 g/cm3 Rotation period 5h 20m Spectral class U History Discoverer H. Olbers, 1827 Vesta is the third-largest known asteroid, 525 kilometers in diameter, discovered in 1807. Among the large asteroids, only Vesta has a surface of basaltic rock from ancient lava flows that may overlay an olivine mantle. This indicates that in the distant past Vesta likely differentiated into layers and underwent many of the same geological processes that the early Earth and Mars underwent. Dozens of Vesta-like asteroids are presumed to have existed at one time, but since then have been broken apart into families of smaller asteroids;.

History Discoverer Eleanor F. Helin, 1989 The asteroid Castalia was the first asteroid to be directly imaged, in August of 1989. Its orbit took it within 11 lunar distances of Earth, allowing it to be scanned with radar from the Arecibo radio telescope. Castalia was found to have a peanut shape, suggesting two 800m diameter pieces held together by their weak mutual gravity. Since then radar measurements of other asteroids has indicated that this contact binary arrangement appears to be common..
