It consists of an F-class white main sequence star and a dim white dwarf. It has an apparent magnitude of 0.34 and is also a binary star system. Procyon, the brightest star in Canis Minor, is the eighth brightest star in the sky. The bright open cluster Messier 41, easy to observe in a small telescope, can be seen near Sirius. With a visual magnitude of -1.46, Sirius has almost twice the brightness of Canopus, the second brightest of all stars, located in the southern constellation Carina. It is a binary star system composed of an A-class main sequence star and a D-type white dwarf. Located in Canis Major, only 8.6 light years from Earth, Sirius is also the fifth closest star system to our own. Sirius, the Dog Star, is the single brightest of all stars. The constellations Canis Major and Canis Minor harbour two of the 10 brightest stars in the sky. The constellation is easy to find in the sky because its brightest stars form a prominent pentagon shape. (It also known as “The Seven Sisters”, or the astronomical designations NGC 1432/35 and M45.)
