About Peacock

It is a blue-white star of class B, far hotter than the Sun and vastly more luminous. Its spectrum shows it is a close binary, two stars too near each other to be seen apart, revealed by the regular shifting of their light.

Most bright stars carry names from Greek, Latin or Arabic. Peacock does not: the name was given to Alpha Pavonis by the British Nautical Almanac Office for an air almanac, so that navigators had a name to call it by. It remains one of the stars used for celestial navigation.

What you see in the piece

Its blue-white colour is its temperature, drawn as is. From most of the northern hemisphere it never rises; use the human eye view from the south to see it in its constellation.

Questions

Why is the star called Peacock?
