Deneb KaitosDeneb Kaitos (Arabic for "tail of Cetus", also known as Diphda "frog", from the Arabic الضفدع الثاني aD-Dafda aθ-θānī "the second frog") is the common name of β Ceti, the brightest star in the constellation Cetus. Deneb Kaitos is easy to locate due to its location in an otherwise dark corner of the sky. Deneb Kaitos has a spectral type falling on the border between G and K, making it a yellowish-orange star somewhat cooler than the Sun. In spite of its cooler nature, Deneb Kaitos is several times brighter than the Sun due to it being more massive and having several times the Sun's radius, as Deneb Kaitos appears to be an older star leaving the main sequence on its way through the red giant phase of its evolution. With an apparent magnitude of 2.04 it ranks among the brighter stars in our night sky, and an absolute magnitude of -0.31. At only 96 light years from the Earth, Deneb Kaitos is one of the nearer stars of a bright apparent magnitude. It can be located at declination -17 59' 11.81" and right ascension of 00:43:35.23 (2000). Ceti, Beta
