VFTS 243 (2MASS J05380840-6909190) is an
O7V type main sequence
star that orbits a stellar mass
black hole.[7] The black hole is around nine times the mass of the
Sun, with the blue star being 25 times the mass of the Sun making the star 200,000 times larger than the black hole. VFTS 243 is located in the
Large Magellanic Cloud inside
NGC 2070 (the
Tarantula Nebula) around 160,000 light years from
Earth.[8][5] The binary has an orbital period of 10.4 days.[4]
