NGC 3754 is a small barred spiral galaxy [1] located in Leo. [2] It is located 447 million light-years away from the Solar System [3] and was discovered on April 5, 1874, by Ralph Copeland. [4]

The luminosity class of NGC 3754 is II [3] and it is listed as a LINER galaxy by SIMBAD, meaning, a nucleus presenting an emission spectrum characterized by broad lines of weak ionized atoms. [5]

NGC 3754 is a member of the Copeland Septet which is made up of 7 galaxies discovered by Copeland in 1874. [6] The other members of the group, are NGC 3745, NGC 3746, NGC 3748, NGC 3750, NGC 3751 and NGC 3753. [7]

Halton Arp noticed the 7 galaxies in an article published in 1966. [8] This group is designated as Arp 320 in which PGC 36010 is part of them. [9]

The 7 galaxies were also observed by Paul Hickson, in which he included them inside his article in 1982. [10] This group is known as Hickson 57, in which NGC 3754 is designated as HCG 57D. [11]
