The brightest star, Alpha Phoenicis, is named Ankaa, an Arabic word meaning 'the Phoenix'. It is an orange giant of apparent magnitude 2.4. Next is Beta Phoenicis, actually a binary system composed of two yellow giants with a combined apparent magnitude of 3.3. Nu Phoenicis has a dust disk, while the constellation has ten star systems with known planets and the recently discovered galaxy clusters El Gordo and the Phoenix Cluster—located 7.2 and 5.7 billion light years away respectively, two of the largest objects in the visible universe. Phoenix is the radiant of two annual meteor showers: thePhoenicids in December, and the July Phoenicids.The constellation does not lie on the galactic plane of the Milky Way, and there are no prominent star clusters. | The brightest star, Alpha Phoenicis, is named Ankaa, an Arabic word meaning 'the Phoenix'.

Phoenix is a small constellation bordered by Fornax and Sculptor to the north, Grus to the west, Tucana to the south, touching on the corner of Hydrus to the south, and Eridanus to the east and southeast. The bright star Achernar is nearby. | Phoenix is a small constellation bordered by Fornax and Sculptor to the north, Grus to the west, Tucana to the south, touching on the corner of Hydrus to the south, and Eridanus to the east and southeast.

Phoenix was the largest of the twelve constellations established by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman. It first appeared on a 35-cm diameter celestial globe published in 1597 (or 1598) in Amsterdam by Plancius with Jodocus Hondius. The first depiction of this constellation in a celestial atlas was in Johann Bayer'sUranometria of 1603.De Houtman included it in his southern star catalog the same year under the Dutch name Den voghel Fenicx, "The Bird Phoenix",symbolising the phoenix of classical mythology.[4] One name of the brightest star Alpha Phoenicis—Ankaa—is derived from the Arabic العنقاءal-‘anqā’ "the phoenix", and was coined sometime after 1800 in relation to the constellation. | Phoenix was the largest of the twelve constellations established by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman.
