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]
Supernova SN 2009jy was discovered in NGC 3200 on March 8, 2009 by a man named Chai. The type of this supernova has not been determined. [5]
