Discovered on 13 September 1999 by J. Broughton at Reedy Creek.
Greensleeves is a timeless old English ballad by an unknown songwriter about his “Lady Greensleeves”. The tune with the original lyrics first appeared in 1652, but it was preceded by a melody that is thought to have originated in the late 1500s.Naming citation (20020427/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
