NGC 3200 explained

NGC 3200
Epoch:J2000
Constellation Name:Hydra
Names:PGC 30108, UGCA 210, MCG -3-26-37, ESO 567-45
Type:SAc
Sbrightness:23.48 mag/arcsec2

NGC 3200 is a large spiral galaxy located in the constellation Hydra. Its velocity relative to the cosmic microwave background is 3,877 ± 25 km/s, which corresponds to a Hubble distance of 57.2 ± 4.0 Mpc (~187 million ly). NGC 3200 was discovered by American astronomer Edward Singleton Holden in 1882.[1]

The luminosity class of NGC 3200 is III and it exhibits a broad HI line.[2]

To date, 21 non-redshift measurements give a distance of 43.086 ± 12.631 Mpc (~141 million ly) which is within the Hubble distance values.[3] Note, however, that the NASA/IPAC database calculates the diameter of a galaxy using the average value of independent measurements, when they exist, and that consequently the diameter of NGC 3200 could be about 116.4 kpc (~380,000 ly) if the Hubble distance were used to calculate it.[4]
