NGC 2336 is a

light years from Earth, which, given its apparent dimensions, means that NGC 2336 is about 200,000 light years across. It was discovered by Wilhelm Tempel in 1876.[2]

Characteristics

NGC 2336 is a

HII regions,[4] emanate from the ring-like structure around the bar. This ring has a radius of approximately 34 arcseconds, which corresponds to 5.3 kpc at the distance of NGC 2336.[5]

In the large arms of the galaxy have been observed 28 HII regions that may host young massive star clusters, and for two of them the nebular emission comprises most of the flux. Three of these HII areas have ages calculated to be 100 to 300 million years and have sizes between 300 and 600 parsecs. It is suggested they are star complexes that may coexist with younger ones. The most massive of the HII regions, number 13, has a mass estimated to be (550±169)×104 M☉ and is 2,600 ly (810 pc) across.[6] Observations in the ultraviolet showed 78 star forming regions, with two of them between the spiral arms and six at the galaxy ring. Their size is comparable to NGC 604, one of the largest nebulae in the Local Group. Star formation is more intense in the inner parts of the arms and at the ring.[7]

Scattered

Ha imaging of the nucleus of NGC 2336.[9] The nucleus is small, with an apparent diameter of 5 arcseconds, while the bulge is large, with a radius of 17 arcseconds.[5] In the centre of NGC 2336 lies a supermassive black hole whose mass is estimated to be 30 million (107.5) M☉ based on Ks bulge luminosity.[10]

Supernova

One

Spectrography performed by William Herschel Telescope on 20–21 October 1987 concluded that it was a type Ia supernova with its maximum approximately 100 days before.[14]

Nearby galaxies

NGC 2336 is the foremost galaxy of a small galaxy group known as the NGC 2336 group.[15] It forms a non-interacting pair with IC 467, which lies 20 arcminutes away.[16]
