 Invention of Phoenix

Phoenix lies near the southern end of Eridanus, close to the bright star, Achernar. It is the largest of the 12 constellations invented at the end of the 16th century by the Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman and represents the mythical bird that was supposedly reborn from the body of its predecessor. Its brightest star is Alpha Phoenicis, magnitude 2.4.

 Best Viewed Objects/Stars

Beta Phoenicis

 A double star. The two stars of magnitudes 4.0 and 4.2 are not easy to divide: a telescope with an aperture of at least 4 in (100 mm) is needed to separate them.

Zeta Phoenicis

 A star that is both variable and double. The brighter component, an eclipsing binary of the same type as Algol, ranges between magnitudes 3.9 and 4.4 every 1 day and 16 hours. The fainter star of 8th magnitude can be seen with a small telescope.
