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.[9]
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)×109M☉. The galaxy has a combined dynamic mass of (7.50±0.87)×1011M☉.[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]
On 20 March 2023, a
supernova was observed in NGC 2613: SN 2023dtc (
Type Ib, mag. 18).[11]
