Alpha Pyxidis
Alpha Pyxidis, Romanization of Greek, Latinised from α Pyxidis, is a giant star in the constellation Pyxis. It is the brightest star in Pyxis, and is easily visible to the naked eye. It has a stellar classification of B1.5III and is a Beta Cephei variable. This star has more than ten times the mass of the Sun and is more than six times the Sun's radius. The surface temperature is and the star is about 10,000 times as Solar luminosity, luminous as the Sun. Stars such as this with more than 10 solar masses are expected to end their life by exploding as a supernova. Naming In Chinese language, Chinese, (), meaning ''Ghost (Chinese constellation), Celestial Dog'', refers to an Asterism (astronomy), asterism consisting of α Pyxidis, HD 73634, e Velorum, KX Velorum, f Velorum, β Pyxidis, γ Pyxidis and δ Pyxidis. Consequently, α Pyxidis itself is known as (, ). [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyxis
Pyxis is a small and faint constellation in the southern sky. Abbreviated from Pyxis Nautica, its name is Latin for a mariner's compass (contrasting with Circinus, which represents a draftsman's compasses). Pyxis was introduced by Nicolas-Louis de Lacaille in the 18th century, and is counted among the 88 modern constellations. The Galactic plane, plane of the Milky Way passes through Pyxis. A faint constellation, its three brightest stars—Alpha Pyxidis, Alpha, Beta Pyxidis, Beta and Gamma Pyxidis—are in a rough line. At magnitude 3.68, Alpha is the constellation's brightest star. It is a blue-white star approximately distant and around 22,000 times as luminosity, luminous as the Sun. Pyxis is located close to the stars that formed the old constellation Argo Navis, the ship of Jason and the Argonauts. Parts of Argo Navis were the Carina (the keel or hull), the Puppis (the stern), and the Vela (the sails). These eventually became their own constellations. In the 19th century ...
