An asteroid spectral type is assigned to asteroids based on their reflectance spectrum, color, and sometimes albedo. These types are thought to correspond to an asteroid's surface composition. For small bodies that are not internally differentiated, the surface and internal compositions are presumably similar, while large bodies such as Ceres ...
Genesis Live is the first live album from the English rock band Genesis, released on 20 July 1973 on Charisma Records.Initially recorded for radio broadcast on the American rock program King Biscuit Flower Hour, the album is formed from the recordings of shows at Free Trade Hall, Manchester and De Montfort Hall, Leicester in February 1973 during the band's tour supporting their fourth studio ...
Sizes are not to scale. An asteroid is a minor planet —an object that is neither a true planet nor an identified comet — that orbits within the inner Solar System. They are rocky, metallic, or icy bodies with no atmosphere, classified as C-type (carbonaceous), M-type (metallic), or S-type (silicaceous). The size and shape of asteroids vary ...
C-type asteroid. C-type (carbonaceous / ˌkɑːrbəˈneɪʃəs /) asteroids are the most common variety, forming around 75% of known asteroids. [1] 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. They have an average density of about 1. ...
The X-group contains the types: core X-type containing the asteroids with the most "typical" spectra. Xe-type of asteroids whose spectra contain a moderately broad absorption band around 0.49 μm. It has been suggested that this indicates the presence of troilite (FeS). There is some correlation between this group and the Tholen E-type.
16 Psyche (/ ˈsaɪkiː / SY-kee) is a large M-type asteroid, which was discovered by the Italian astronomer Annibale de Gasparis, on 17 March 1852 and named after the Greek goddess Psyche. [10] The prefix "16" signifies that it was the sixteenth minor planet in order of discovery.
7 Iris is a large main-belt asteroid and possible remnant planetesimal orbiting the Sun between Mars and Jupiter. It is the fourth-brightest object in the asteroid belt. 7 Iris is classified as an S-type asteroid, meaning that it has a stony composition.
Deconvolved with MISTRAL algorithm. Main-belt asteroids > 200 km that were not imaged are (451) Patientia, (65) Cybele and (107) Camilla. Trojan (624) Hektor may also be in this size range. VLT/SPHERE images of a large number of asteroids 100 to 210 km in diameter, to scale. (10) Hygiea, (31) Euphrosyne and (8) Flora have collisional families ...
