NGC 3735 is a spiral galaxy in the constellation of Draco. Its velocity with respect to the cosmic microwave background is 2,776±6 km/s, which corresponds to a Hubble distance of 133.5 ± 9.4 Mly (40.94 ± 2.87 Mpc). Additionally, 19 non-redshift measurements give a closer mean distance of 123.87 ± 3.81 Mly (37.979 ± 1.167 Mpc). It was discovered by German-British astronomer William Herschel on 7 December 1801.

NGC 3735 is a Seyfert II galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.

Supermassive black hole

Based on measurements of the near-infrared K-band luminosity of the galaxy's bulge, NGC 3735 has a supermassive black hole with a mass of 1×107.6M☉ (40 million solar masses).

Nuclear maser source

A survey conducted in 1996 and 1997 for H2O maser emission in the active galactic nuclei of 29 galaxies found one new maser in NGC 3735.

NGC 3735 group

NGC 3735 is a member the NGC 3735 group (also known as LGG 240), which contains three galaxies, including UGC 6552[d] and UGC 6711[d].
