J-type asteroid, the Glossary

J-type asteroids are asteroids with spectra similar to that of diogenite meteorites and so, presumably, to the deeper layers of the crust of 4 Vesta.^[1]

Absorption band

In quantum mechanics, an absorption band is a range of wavelengths, frequencies or energies in the electromagnetic spectrum that are characteristic of a particular transition from initial to final state in a substance.

Asteroid

An asteroid is a minor planet—an object that is neither a true planet nor an identified comet— that orbits within the inner Solar System.

Asteroid spectral types

An asteroid spectral type is assigned to asteroids based on their reflectance spectrum, color, and sometimes albedo. J-type asteroid and asteroid spectral types are asteroid spectral classes.

Diogenite

Diogenites are a group of the HED meteorite clan, a type of achondritic stony meteorites.

V-type asteroid

A V-type asteroid or Vestoid is an asteroid whose spectral type is that of 4 Vesta. J-type asteroid and v-type asteroid are asteroid spectral classes.
