This star is a yellow-orange main sequence dwarf star of spectral and luminosity type G0 V, with less than 108 percent of Sol's mass, under 111 percent of its diameter, and about 1.2 times its luminosity.
CHARA (Beta Canum Venaticorum). A lovely name for a northern star that vaults the heavens in northern spring, "Chara" from Greek meaning "joy.
Chara is the name assigned either to this star or, more generally, to the "southern hound" of the constellation Canes Venatici; the northern "hound" is called Asterion, a name not generally assigned any particular star.
