Silly is asteroid #129234, also known as 2005 PS₅. Silly’s orbit is characterized by a semi-major axis of 2.24 Astronomical Units, an eccentricity of 0.04, a period of revolution of 1’227 days, and an inclination of 6.7 degrees. Silly was discovered by the French engineer and amateur astronomer Bernard Christophe at the Saint-Sulpice Observatory (Observatoire de Saint-Sulpice, IAU-Code 947).

Silly is named after the French optician and amateur astronomer Didier Silly. He was born in 1950 and is a friend of the discoverer of the asteroid Silly. Several places, especially in France, and persons bear the name Silly, but this name seems to be not derived from a French word. At least the word silly doesn’t exist in the French language as far as I could figure out. According to Wiktionary is English the only language, in which the word silly exists.

Nothing outstanding is known about Didier Silly and only what is said about him in the official naming citation for the asteroid #129234 is publicly known about him at all. So the astrological interpretation of the asteroid Silly is simple. Silly by its aspects indicates that somebody or something is silly. In horary charts, this would be the advice not to follow a certain path.
