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.
can be seen between Pegasus and Delphinus
and is in the shape of a distorted rectangle.
