Astraea was the fifth [[asteroid]] found, on [[December 8]], [[1845]] by [[Karl Ludwig Hencke|K. L. Hencke]]. It was his first of two asteroid discoveries. The second was [[6 Hebe]]. An amateur astronomer and post office employee, Hencke was looking for [[4 Vesta]] when he stumbled on Astraea. The King of [[Prussia]] awarded him with an annual pension of 300 US$ ([[1968]] dollars) for the discovery.<ref>{{cite web|title=DAWN: A Journey to the Beginning of the Solar System|url=http://dawn.jpl.nasa.gov/DawnCommunity/flashbacks/fb_09.asp|publisher=NASA: Jet Propulsion Laboratory; California Institute of Technology|accessdate=20 July 2013}}</ref>

Photometry indicates [[prograde]] rotation, that the north pole points in the direction of [[right ascension]] 9 h 52 min, [[declination]] 73° with a 5° uncertainty.<ref name=Lopez-Gonzales /> This gives an [[axial tilt]] of about 33°.
