How many stars vs. bright stars are in the Scorpius Constellation?

My teacher gave us an assignment on a constellation, and I got Scorpius. One of the questions was how many stars are in the constellation, and I figured it was 18, but then it asked how many bright stars are there, and I think that might be 18, and there are actually like 60 stars in the constellation. Please help!|||According to wikipedia, there are 47 Bayer/Flamsteed stars and 13 "bright" stars in the constellation. By bright they apparently mean magnitude 3.0 or brighter. "Bright" is not a term that has a fixed meaning; astronomers often consider anything visible to the naked eye as bright. The Bayer/Flamsteed count is the number of stars listed in those two old naked-eye star atlases. I doubt anyone has attempted to count all the stars actually in the constellation. Being close to the center of the Milky Way, Scorpius has millions of stars in it.





Note that a constellation consists of a defined area of sky. The stick figures used to depict constellations are arbitrary; if you look at several sources you will find multiple ways of connecting the dots using various numbers of dots.|||It depends on what they mean by bright. Probably the 18 brightest is as good an answer as any. And if you include every dim and distant star in the Milky Way it is probably billions, because the densest part of the Milky Way is in Scorpius.|||From what i read, i can tell you that Scorpius has "many" bright stars.
