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).

[2] Halton Arp describes these as an example of galaxies by presenting a bridge of matter between them and having a high surface gloss.

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.

[5] The NASA/IPAC database indicates that NGC 3800 is possibly a field galaxy, that is, it does not belong to a cluster or group and is therefore gravitationally isolated.
