Encyclopedia
J-type asteroids are asteroid
s with spectra similar to that of diogenite
meteorites and so, presumably, to the deeper layers of the crust of 4 Vesta
.
Their spectra are rather similar to that of the V-type asteroid
s but have a particularly strong 1 μm absorption band.
Examples are 2442 Corbett
, 3869 Norton
, 4005 1979 TC2, and 4215 1987 VE1.
