NGC 3750 has a surface brightness of magnitude 23.7[2] and is classified a LINER galaxy by SIMBAD, meaning it has a nucleus, presenting an emission spectrum characterized by broad lines of weakly ionized atoms.[6]

Copeland Septet

NGC 3750 is a member of the Copeland Septet which is made up of 7 seven galaxies discovered by Copeland.[7] The other members are NGC 3745, NGC 3746, NGC 3748, NGC 3751, NGC 3753 and NGC 3754.[8]

Halton Arp noticed the galaxies in the group, whom he published in his article in 1966.[9] This group is designated as Arp 320 along with another galaxy, PGC 36010.[10]

This group was also observed by Paul Hickson whom he included in his article in 1982.[11] The group is known as Hickson 57, in which NGC 3750 is designated is HCG 57C.[12]
