Q-type asteroids are relatively uncommoninner-beltasteroids with a strong, broad 1micrometreolivine andpyroxene feature, and a spectral slope that indicates the presence of metal. There are absorption features shortwards and longwards of 0.7 μm, and the spectrum is generally intermediate between theV andS-type.
Q-type asteroids are spectrally more similar toordinary chondrite meteorites (typesH,L,LL) than any other asteroid type. This has led scientists to speculate that they are abundant, but only about 20 of this type has been characterized.[1] Examples of Q-type asteroids are:1862 Apollo,2102 Tantalus,3753 Cruithne,6489 Golevka, and9969 Braille.
