Encyclopedia : G : GT : GTY : G-type asteroid
G-type asteroids are a relatively uncommon type of carbonaceous asteroid. The most notable asteroid in this class is 1 Ceres.
Characteristics
Generally similar to the C-type objects, but containing a strong ultraviolet absorption feature below 0.5μm. An absorption feature around 0.7μm may also be present, which is indicative of phyllosilicate minerals such as clays or mica.In the SMASS classification the G-type corresponds to the Cgh and Cg types, depending on the presence or absence (respectively) of the absorption feature at 0.7μm. The G-type, C-type and some rare types are sometimes collected togehter into a wider C-group of carbonaceous asteroids.
