- Vanadium is a chemical element; it has symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.

The peacock is one of the 12 figures introduced into the southern skies at the end of the 16th century from the observations by the Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman. Pavo seemingly represents not the common blue, or Indian, peacock commonly seen in parks but its larger, more colourful, and more aggressive cousin, the Java green peacock which Keyser and de Houtman would have encountered in the East Indies. Pavo was first depicted in 1598 on a globe by Petrus Plancius and first appeared in print in 1603 on the Uranometria atlas of Johann Bayer. As visualized by Plancius and Bayer the peacock had a more expansive tail, but its feathers were later trimmed by Lacaille to make room for his own invention Telescopium to the north.
