Which constellations can you find easily?

There are 88 constellations on the official IAU list. 48 of them are from Ptolemy’s second century publication. Many of the constellations however are not so easy to find or are not so interesting. The IAU list intended to allocate the entire sky into constellation groups. In doing so many of the lesser known constellations shapes are not descriptive or have no prominent stars. This page aims to clarify which constellations are both easy to locate and which are easy to imagine from the formation of the stars. We focus on the prominent constellations, predominantly those from Ptolemy’s list. This includes many constellations that are important for navigation, include the brightest stars in the sky and form shapes that depict humans and animals. Ptolemy’s list included the majority of widely known constellations including the zodiacs, the many greek mythological constellations and those that identify the polar north.
