NGC 6400 is a galactic open star cluster in the constellation Scorpio and about 950 parsecs from Earth. It was discovered on May 13, 1826 by James Dunlop with a 9-inch reflector telescope, who described it as a very faint cluster that looked like a faint nebula, and pointed out, among other things, that the density of stars is clear towards the center is increased.
