K-type asteroids are relatively uncommon asteroids with a moderately reddish spectrum shortwards of 0.75 üm, and a slight bluish trend longwards of this. They have a low albedo. Their spectrum resembles that of CV and CO meteorites. A larger K type is 9 Metis.
These asteroids were described as "featureless" S-types in the Tholen classification. The K-type was proposed by J. F. Bell and colleagues in 1988 for bodies having a particularly shallow 1 üm absorption feature, and lacking the 2 üm absorption. These were found during studies of the Eos family of asteroids.
