Asteroid 7464, Vipera, was discovered on November 15, 1987 by Antonin Mrkos at Klet Observatory near Cesky Budovice, Czech Republic. It has a period of 4 years, 39 days.
It was named for the viper family of snakes, Viperidae, and in particular Vipera berus, which also goes by various common names such as adder, European adder, common viper, and northern viper. It is an endangered species of European snake that inhabits Klet Mountain, upon which Klet Observatory is situated.
Vipera berus, the European adder.
Astrologically, Vipera seems to indicate poisonous snakes (particularly true or pit vipers), hidden treachery or evil, poisoned happiness, "a snake in the grass".
The glyph for Vipera is mine.
