It was discovered on 29 October 1935, by French astronomer Guy Reiss at the North African Algiers Observatory in Algeria.
[2] Michelle is a member of the Flora family, one of the largest populations of stony S-type asteroids in the entire main-belt.
[12] In October 2008, a group of French and Japanese astronomers obtained two rotational light-curves of Michelle from photometric observations.
Light-curve analysis gave a well defined rotation period of 5.9748 and 5.9766 hours with a brightness variation of 0.20 and 0.13 magnitude, respectively (U=3/3).
[4][5] The Collaborative Asteroid Lightcurve Link adopts an albedo of 0.263 and a diameter of 7.10 kilometers, taken from Petr Pravec's 2012-revised WISE results.
