The stars in a constellation like Scorpius appear to form a pattern, but are not a unit. A constellation consists of many stars spread out over a wide distance and of different temperatures. So there is no temperature that a constellation can be said to be.
The Constellation Scorpius has 17 stars. Scorpius is easy to see in the night sky because it looks like a scorpion. The tail or stinger is made with the stars Shaula and Lesath. The heart is the star Antares.
