NGC 3003 is a nearly edge-on barred spiral galaxy in the constellation of Leo Minor,[1] discovered by German-British astronomer William Herschel on December 7, 1785.[5] It has an apparent visual magnitude of 11.78,[4] and spans an angular size of 5.7′ × 1.4′.[1] NGC 3003 is located at a distance of 19.5 Mpc from the Sun,[3] with a recessional velocity of 1,474 km/s.[2]
The morphological classification of NGC 3003 is SBbc,[4] indicating a barred spiral (SB) with moderate to loosely wound spiral arms (bc). The shape of the galaxy suggests it has been disturbed, possibly by NGC 3021. The two have a projected separation of about 200 kpc. NGC 3003 displays high luminosity in the hydrogen-alpha line, showing a bright nucleus and many prominent H II regions.[6] 25 independent star forming regions have been identified, including the nuclear region. There is a bright and compact region to the southwest, which may be the remains of a dwarf galaxy or an intense H II region.[7]
Supernova and luminous blue variable
One supernova and one luminous blue variable have been observed in NGC 3003:
- SN 1961F (Type II, mag. 13.1) was discovered by Paul Wild on 21 February 1961.[8][9][10]
- AT 2020jev (Type LBV, mag. 20.33) was discovered by Pan-STARRS on 4 May 2020.[11][12]
