An astronomical object that appears starlike on a
photographic plate but possesses many other
characteristics, such as a large redshift, that prove that
it is not a star.
The name quasar is a contraction of the term quasistellar
object (QSO), which was originally applied to these objects
for their photographic appearance.
The objects appear starlike because their angular diameters
are less than about 1 second of arc, which is the
resolution limit of ground-based optical telescopes imposed
by atmospheric effects.
