3309 Brorfelde is an inner main belt asteroid. It is a member of the Hungaria family.[1] It was discovered on 28 January 1982 by K. S. Jensen, at Brorfelde Observatory in Denmark, for which it was named.

Brorfelde measures approximately 6 km in diameter.

In 2005 it was reported that lightcurve observations indicate the possibility of a moon orbiting Brorfelde. In 2006 it was confirmed at the Palmer Divide Observatory that 3309 Brorfelde is a binary asteroid.[2]
