September 24 – Asteroid 318 Magdalena

Asteroid 318 Magdalena, discovered on September 24th 1891 by Auguste Charlois, is a main belt asteroid of about 105 to 106 km diameter, of unknown composition. The reason the name was chosen remains a mystery.

This makes it very difficult to say anything much of interest about this object, leading to a very short blog.  I’ll fill this one out a little with the orbital facts and figures for our mysterious friend Magdalena.
