Its central condensation is the star cluster R136, one of the most energetic star clusters known.[3] It holds a number of massive stars, including the most massive star known, R136a1, at 315 {{Solar mass}} and 8.7 million {{Solar luminosity}}.[4] References1. ^1 2 {{cite simbad|title=NGC 2070|accessdate=11 August 2017}} 2. ^{{cite journal|bibcode=1963IrAJ....6...74S|title=A Catalogue of Clusters in The LMC|journal=Irish Astronomical Journal|volume=6|pages=74|language=en|last1=Shapley|first1=H.|last2=Lindsay|first2= E.
