The luminosity class of NGC 3049 is I-II and it has a broad HI line. It also contains regions of ionized hydrogen and is a starburst galaxy. NGC 3049 is also a field galaxy, that is to say it does not belong to a cluster or group and is therefore gravitationally isolated.[1] NGC 3049 is a galaxy whose core shines in the field of ultraviolet. It is listed in the Markarian catalog under the reference Mrk 710 (MK 710).[3]
To date, 11 non-redshift measurements yield a distance of 23.136 ± 6.782 Mpc (∼75.5 million ly),[2] which is within the Hubble distance. Note, however, that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy and that consequently the diameter of NGC 3049 could be approximately 19 .2 kpc (∼62,600 ly) if Hubble distance was used to calculate it.[2]
