Constellations are divided into two groups. The Big and Small Dipper for example are always in the night sky and called circumpolar constellations. There are also seasonal constellations due to the Earth’s motion. A spring constellations such as Virgo can seen rising in the east after sunset. Look for bright star Spica.
