Denebola (Beta Leonis)
The second brightest star in the constellation Leo and the easternmost of a prominent triangle of stars to the east of Regulus. Denebola marks the Lion's tail, its name coming from an Arabic phrase that means exactly that. It is a main-sequence A star, a Delta Scuti star, and, most interestingly, like Vega, seems to be encircled by a disk of infrared-emitting dust. Viewed through a telescope, it also appears to have an orange companion, but the two stars are not physically connected.
