Encyclopedic overview

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. In 1888, Danish astronomer J. L. E. Dreyer described it as "very faint, very large, very much extended 122°". It is located at an estimated distance of 67 million light years. In the B band of the UBV photometric system, the galaxy spans 4.70′ by 0.80′ with the major axis aligned along a position angle of 113°. It is a relatively isolated galaxy with no nearby companions. R. B. Tully in 1988 assigned it as a member of the widely displaced Leo Cloud.

The morphological classification of NGC 3044 is SBc, 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°±4° to the plane of the sky. 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.
