• V-type asteroid — The spectra of the V type asteroids or Vestoids are similar to that of 4 Vesta, by far the largest asteroid in this class (hence the name). A large proportion have orbital elements similar to those of 4 Vesta, either close enough to be part of… …   Wikipedia

• T-type asteroid — T type asteroids are rare inner belt asteroids of unknown composition with dark, featureless and moderately red spectra, and a moderate absorption feature shortwards of 0.85 µm. No direct meteorite analog has been found to date. Thought to be… …   Wikipedia

• A-type asteroid — A type asteroids are relatively uncommon inner belt asteroids that have a strong, broad 1 µm olivine feature and a very reddish spectrum shortwards of 0.7 µm. They are thought to come from the completely differentiated mantle of an asteroid.A… …   Wikipedia

• R-type asteroid — R type asteroids are moderately bright, relatively uncommon inner belt asteroids that are spectrally intermediate between the V and A type asteroids. The spectrum shows distinct olivine and pyroxene features at 1 and 2 micrometres, with a… …   Wikipedia

• Q-type asteroid — Q type asteroids are relatively uncommon inner belt asteroids with a strong, broad 1 micrometre olivine and pyroxene feature, and a spectral slope that indiciates the presence of metal. There are absorption features shortwards and longwards of… …   Wikipedia

• K-type asteroid — K type asteroids are relatively uncommon asteroids with a moderately reddish spectrum shortwards of 0.75 mu;m, and a slight bluish trend longwards of this. They have a low albedo. Their spectrum resembles that of CV and CO meteorites. These… …   Wikipedia

• L-type asteroid — L type asteroids are relatively uncommon asteroids with a strongly reddish spectrum shortwards of 0.75 mu;m, and a featureless flat spectrum longwards of this. In comparison with the K type, they exhibit a more reddish spectrum at visible… …   Wikipedia
