The Huge... Scratch that, Tiny Blackhole

NASA has just discovered the smallest known black hole. The black hole discovered using the Rossi X-ray Timing Explorer, a small satellite placed in orbit in 1995.

The black hole is only 3.8 times the mass of our own sun and is part of a binary system comprised of this black hole and an orbiting star. This is extremely small, about half of the mass of the previous record holder and billions of times smaller than the largest black holes.

If Einsteins theories hold true a black hole with a mass 3.8 times that of our sun, would only be 15 miles across; the size of a city.
