NGC 5709 = NGC 5703 is a 13.6 mag light barred spiral galaxy of the Hubble type SBa in the constellation Bear Guardian .
It was discovered on May 16, 1784 by Wilhelm Herschel with an 18.7-inch reflector telescope, who called it “Two. 3 ′ distant, on the same parallel; ... the preceding [NGC 5709] is eF, vS, verified with 240 power “. The second galaxy mentioned is NGC 5699/5706 .
Due to an incorrect position specification by Herschel of more than one degree, Dreyer noted “lost” for this galaxy when creating the catalog. The discovery of Édouard Stephan on May 12, 1883 was recorded as NGC 5709 and has been listed under this number to this day. Herschel's mistake could only be discovered and corrected in 1912.
