This comparatively modern constellation can be found between Cassiopeia and Cygnus from this week
We began the month with the faint constellation of Cepheus, and end the month with the even fainter constellation of Lacerta, the Lizard.
Whereas Cepheus was one of the original 48 constellations defined by Ptolemy in the second century AD, Lacerta is comparatively modern, having been defined in 1687 by the Polish astronomer Johannes Hevelius. Both constellations are now part of the International Astronomical Union’s 88 modern constellations.
