Aja is the outer satellite of Extaris which unlike the other 4, is rocky.

Unlike the others, it also occupies an extremely elliptical orbit (eccentricity 0.55) which is inclined to the equatorial plane by 19° in a retrograde manner.

These characteristics clearly imply that Aja was not formed with the planet, but was gravitationally captured eons ago.

No record of first observations of Aja has been found.
