B-type giant star in the constellation Pyxis
Alpha Pyxidis ,Latinised fromα Pyxidis , is agiant star in theconstellation Pyxis . It is the brightest star in Pyxis, and is easily visible to thenaked eye . It has astellar classification of B1.5III and is aBeta Cephei variable . This star has more than ten times themass of the Sun and is more than six times theSun's radius . The surface temperature isK luminous as the Sun .[ 3] [ 4] [ 8] supernova .[ 11]
