International Astronomical Union, the world authority for assigning names to CELESTIAL objects, officially recognizes 88 constellations that cover the entire sky.
Astronomers describe star brightness in terms of MAGNITUDE. The magnitude of a star is based on its scale, DEVISED by a Greek astronomer about 2000 years ago. He numbered groups of stars based on their brightness as seen from the Earth — the brightest ones were called first magnitude stars, the next brightest were second magnitude, and so on up to the sixth magnitude, the FAINTEST visible ones - the brightest star in the night sky is Sirius. Shortly, The brightness of a star depends on its SURFACE temperature and size.
As regards the color of a star, it also depends on surface temperature. .A star might appear to have a single color, but actually it EMITS a broad spectrum of colors, potentially including everything from radio waves and infrared rays to ultraviolet beams and gamma rays.
