NGC 3044 is a barred spiral galaxy in the equatorial constellation of Sextans. It was discovered on December 13, 1784, by German-born English astronomer William Herschel. [9] [10] In 1888, Danish astronomer J. L. E. Dreyer described it as "very faint, very large, very much extended 122°". [11] It is located at an estimated distance of 67 million light years. [2] In the B band of the UBV photometric system, the galaxy spans 4.70 by 0.80 [5] with the major axis aligned along a position angle of 113°. [7] It is a relatively isolated galaxy with no nearby companions. [7] R. B. Tully in 1988 assigned it as a member of the widely displaced Leo Cloud. [3]

The morphological classification of NGC 3044 is SBc, [6] indicating a barred spiral (SB) with somewhat loosely-wound spiral arms (c). It is being viewed edge-on, with a galactic plane that is inclined at an angle of 79°± to the plane of the sky. [12] The disk appears lob-sided and disturbed, suggesting a recent merger or interaction. There is a diffuse ionized gas extending to 1  kpc above the center of the plane. [7]

The stars in the galaxy have a combined mass of approximately 1.01×1010  M , [6] and the star formation rate is 2.77 M·yr–1. [6] The total mass of the atomic gas in this galaxy is 3.5×109 M, [7] and it has a dust mass of 1.6×108 M. [3] The galaxy as a whole has a dynamic mass of 6.4×1010 M. [7]

One supernova has been observed in NGC 3044: SN 1983E (type II, mag. 14) [13] was discovered by Natalʹja Metlova on 13 March 1983, at an offset 29 east, 11″ south of the galaxy. [14] [15] [16]
