Winter constellations are the constellations that are best observed in the evening night sky from late December to late March in the northern hemisphere and from late June to late September in the southern hemisphere. The most prominent northern winter constellations are Auriga, Canis Major, Canis Minor, Carina, Eridanus, Gemini, Monoceros, Orion and Taurus. Southern winter constellations are the same as northern summer constellations. Autumn constellations are the constellations that are best observed in the night sky from late September to late December in the northern hemisphere and from late March to late June in the southern hemisphere. Autumn is a good time to see a number of notable constellations, including the zodiac constellations of Aquarius, Aries and Pisces, and the constellations in the Perseus family: Andromeda, Perseus, Cassiopeia, Pegasus, Triangulum, Cetus and Cepheus.
