Equuleus, or
Little Horse, is one of the smallest constellations. While it is an old constellation, not much mythology surrounds it. It's mentioned in Ptolemy's
Almagest, but may have been first created by
Hipparchus.
It's uncertain where the name "little horse" comes from now, but it's thought to represent
Celeris, the half brother of
Pegasus. The original name of the constellation may have been
Equus Primus, meaning "the First Horse", since it rises just before Pegasus in the sky.
The brighest star of the constellation,
Kitalpha or
Al Kit ah la Faras, means "Part of the Horse" and does not exceed 4th magnitude. The only other objects within this constellation worth noting would be the double star
epsilon Equulei, formed by a yellow fifth magnitude and white-blue seventh magnitude star.
The
constellation can be seen between Pegasus and
Delphinus and is in the shape of a distorted rectangle.
