What constellations are there in the northern sky in summer? Where is each constellation and what are its characteristics?

Looking north: The Big Dipper is in the northwest sky, and arcturus is on the left. Little Beidou (Ursa minor) is on the left of Polaris, and Cassiopeia is on the right, with the number 3. Perseus is rising from the low altitude, and Pegasus and Andromeda are further east.

Looking south: overhead is the summer triangle: Vega (Lyra), Tianjin IV (Cygnus) and Altair (Eagle). The Milky Way extends from southwest to northeast and divides into two parts in the position of Cygnus, which is a big crack in Cygnus. In the west are Ophiuchus and the head and tail of Ophiuchus, and below are Sagittarius and Scorpio. In the southeast are Aquarius and Capricorn. (Excerpted from Stars on the Planet)
