M83, Southern Pinwheel Galaxy has a newly found dwarf satellite 85,000 light years from its host. This satellite galaxy was designated dw1335-29 and could be an irregular or a transition dwarf.

Finding new satellites of galaxies beyond the Local Group such as Messier 83 could provide essential insights on galaxy formation in a cosmological context.
