NGC 2613 is a spiral galaxy in the southern constellation of Pyxis, next to the western constellation border with Puppis. It was discovered by the German-born astronomer William Herschel on November 20, 1784. [8] With an apparent visual magnitude of 10.5, the galaxy is faintly visible using a telescope with a 100 mm (4 in) aperture. It appears spindle-shaped as it is almost edge-on to observers on Earth.

The morphological classification of NGC 2613 is SA(s)b, [4] indicating a spiral galaxy with no bar or ring, and moderately tightly-wound spiral arms. It is inclined by an angle of approximately 79° to the line of sight from the Earth [5] and is oriented with the long axis along a position angle of 133°. [4] The radius of neutral hydrogen in the galaxy is about 35 kpc, [10] and the mass of the neutral hydrogen is (8.73±0.32)×109  M☉ . The galaxy has a combined dynamic mass of (7.50±0.87)×1011 M☉. [5]

NGC 2613 has an active galactic nucleus that is deeply embedded in obscuring gas and dust. [5] Emission data collected by the Very Large Array shows a feature resembling a tidal tail along the southeast side of the galaxy, which was most likely produced by an interaction with the small companion galaxy, ESO 495-G017, now located to the northwest of NGC 2613. [10]

One supernova has been observed in NGC 2613. SN 2023dtc (Type Ib, mag. 18.604) was discovered by ATLAS on 20 March 2023. [11]
