How do you describe the stars of the first magnitude?
"First magnitude" usually means the brightest 21 stars, as seen from Earth. Another definition is stars with apparent magnitudes 0.5 to 1.5. This definition excludes the very brightest stars, like Sirius. They are the first stars that become visible after sunset and they all have names. Examples are Altair, Aldebaran, Capella, Spica, Antares, Fomalhaut, Deneb, Regulus, Sirius, etc. There can be confusion because First Magnitude stars are not stars with an "apparent magnitude" of exactly "one". They are just the brightest stars, but naturally their magnitudes are close to one.
