NGC 1003 is a spiral galaxy at the western edge of the Perseus constellation.[9] It is located at a distance of about 36 million light years from the Milky Way and is receding with a heliocentric radial velocity of 624 km/s.[4] This galaxy was discovered by the Anglo-German astronomer William Herschel on October 6, 1784, who described it as "pretty faint, large, extended 90°±, much brighter middle, mottled but not resolved".[10] It is a member of the NGC 1023 group of galaxies.[6]

The morphological class of NGC 1003 is SAcd, which means it is an unbarred spiral galaxy (SA) with somewhat loosely-wound spiral arms (cd). It is inclined by an angle of 70° to the line of sight from the Earth, with the major axis aligned along a position angle of 276°. The visual disk of the galaxy shows a substantial warping in the eastern side, turning it almost face on. The estimated star formation rate is 0.40 M☉·yr−1.[7] It has a virial mass of 3×1012 M☉ and a mass-to-light ratio of 0.7.[8]

One supernova has been observed in NGC 1003: SN 1937D (type Ia, mag. 12.8)[11][12] was discovered by Fritz Zwicky on 9 August 1937.[13]
