NGC 1024 is a largespiral galaxy of type Sab[1] located in theconstellation Aries. Its speed relative to thecosmic microwave background is 3,306 ± 16 km/s, which corresponds to a Hubble distance of 48.8 ± 3.4 Mpc (~159 million light-years).[2] NGC 1024 was discovered by German-BritishastronomerWilliam Herschel in 1786.[3]
NGC 1024 was used in theAtlas of Peculiar Galaxies as an example of a motley galaxy.[3]
Theluminosity class of NGC 1024 is I-II and it has a broad HI line. With asurface brightness equal to 14.02 mag/am^2, we can qualify NGC 1024 as alow surface brightness (LSB) galaxy. LSB galaxies are diffuse (D) galaxies with a surface brightness less than onemagnitude lower than that of the ambientnight sky.[3]
To date, five non-redshift measurements yield a distance of 46.260 ± 3.155 Mpc (~151 million ly), which is within theHubble distance range.[4]
NGC 1024 is the largest and brightest of a small group of three galaxies named after it. The other two galaxies in the NGC 1024 group areNGC 990 andNGC 1029.[5] On the other hand, NGC 1024 and NGC 1029 form a pair of galaxies.[6]
