The black hole candidate in the Large Magellanic Cloud with a mass around 10 solar masses is LMC X-1.
LMC X-1 is an X-ray binary in the Large Magellanic Cloud, a satellite galaxy of the Milky Way about 180,000 light-years away. Its black hole has an estimated mass of roughly 10.9 solar masses and orbits a much more massive companion star every 3.9 days.
The system was first detected as an X-ray source in 1969, following observations made with a sounding rocket launched in 1968. The X-rays come from gas pulled from the companion star and heated as it falls toward the black hole.
A common mix-up is M33 X-7, another stellar-mass black-hole binary, but it lies in the Triangulum Galaxy. LMC X-3 is also an X-ray source in the Large Magellanic Cloud, yet its compact object is generally identified as a black hole with different system properties. Cyg X-3 is a separate Galactic X-ray binary.
