NGC 5589 = NGC 5588 is a 13.3 mag bright barred spiral galaxy of the Hubble type SBa in the constellation Bear Keeper and about 155 million light years away from the Milky Way.
It was discovered together with NGC 5590 during an observation on May 1, 1785 by Wilhelm Herschel with an 18.7-inch reflector telescope, who marked it with “Two. Both vF, S, distance 6 ′ or 7 ′ “described ( NGC 5589 ). John Herschel watched her twice; on April 24, 1827, he confirmed his father's discovery; his earlier observation on May 9, 1826 led to the second catalog entry under NGC 5588 with slightly different position data .
