Southern Sky Pavo 1 oz colorized silver proof coin Australia 2013

The Pavo or 'Peacock' constellation is composed of seven main stars. four with known planets, which resemble the iridescent 'eyes' in a peacock's tail.
The first magnitude star and the constellation's only named star is aPavonis (Alpha Pavonis), which is known too as 'Peacock'. It is 700 times brighter than our own sun.
Another sun-like star in the constellation is Pavonis, a yellow-white dwarf star that is thought by some astronomers to have orbiting planet as there is some evidence to suggest its existence.
Sub giant Pavonis (Delta Pavonis) is approximately 19.9 light years from Earth, and though brighter than our sun, it has a lower temperature, typical of its evolution into a red giant. Astronomers at the SETI Institute in California consider Delta Pavonis' habitable zone an attractive target for extra-terrestrial intelligence.
YPavonis (Gamma Pavonis) is larger and brighter than Earth's sun, and was ranked highly by NASA's Terrestrial Planet Finder project in its proposed quest for rocky planets.
Two nearby galaxies inhabit the Pavo constellation, and are named in the New General Catalogue of Nebulae and Clusters of Stars. NGC 6744 is a spiral galaxy about 30 million light years from Earth and similar in appearance to our own Milky Way. More than six times more distant is NGC 6782, a barred spiral galaxy.
