NGC 6125 = NGC 6127 = NGC 6128 is a 12.0 mag bright elliptical galaxy of the Hubble type E0 in the constellation Dragon in the northern sky . It is an estimated 224 million light years from the Milky Way and about 90,000 light years in diameter.
In the same area of the sky is u. a. the galaxy NGC 6130 .
The object was discovered on April 24, 1789 by Wilhelm Herschel with an 18.7-inch reflector telescope, who described it as "pF, pS, lE". Due to an error in Herschel's position information , Swift's observations on June 28 and July 6, 1886, also flawed and with slightly different descriptions, led to two further entries in the catalog under NGC 6127 and NGC 6128 .
