NGC 3800 is an intermediate spiral galaxy located in the constellation Leo. Its speed relative to the cosmic microwave background is 3,653 ± 24 km/s, which corresponds to a Hubble distance of 53.9 ± 3.8 Mpc (~176 million ly).[1] NGC 3800 was discovered by German-British astronomer William Herschel in 1784.
NGC 3799 and NGC 3800 are two gravitationally interacting galaxies and appear in Halton Arp's Atlas of Peculiar Galaxies under the symbol Arp 83.[2] Halton Arp describes these as an example of galaxies by presenting a bridge of matter between them and having a high surface gloss.
The luminosity class of NGC 3800 is II and it has a broad HI[1] line.
To date, four non-redshift measurements give a distance of 42.125 ± 1.162 Mpc (~137 million ly),[3] which is well outside the Hubble distance values. 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 3800 could be approximately 32.8 kpc (~107,000 ly) if we used the Hubble distance to calculate it.
