NGC 6509 is a spiral galaxy in the equatorial constellation of Ophiuchus. It was discovered on July 20, 1879 by the French astronomer Édouard Stephan.[6] This galaxy is located at a distance of 95.3 million light-years (29.22 Mpc) from the Milky Way,[3] and is receding with a heliocentric radial velocity of 1,814 km/s.[2]
This is a bulge-less disk galaxy[7] with a morphological classification of Sd.[4] The plane of the galaxy is inclined at an angle of 41°±4° to the plane of the sky, and the oval outline is oriented along a position angle of 280.8°±1.1°[7] with an angular span of 1.6′.[4]
The eastern side of this galaxy lies in the foreground of a radio source designated 4C +06.63.[7]
