NGC 1003 is: a spiral galaxy at the western edge of the Perseus constellation. 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. 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". It is a member of the NGC 1023 group of galaxies.
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. It has a virial mass of 3×10 M☉ and a mass-to-light ratio of 0.7.
A type Ia supernova was discovered in the galaxy by F. Zwicky in 1937. And subsequently designated SN 1937D.
