NGC 3751 is a type E-S0[1] lenticular galaxy located in the Leo constellation.[2] It is located 450 million light-years away from the Solar System[3] and was discovered by Ralph Copeland on April 5, 1874.[4]
To date, a non-redshift measurement gives a distance of approximately 138,000 Mpc (450 million light-years) for NGC 3751. This value is within the Hubble Distance values.[5]

NGC 3751 is a member of the Copeland Septet.[6] The other members are NGC 3745, NGC 3746, NGC 3748, NGC 3750, NGC 3753 and NGC 3754.[7]
Halton Arp noticed the 7 galaxies in which he published inside his article in 1966.[8] This group is known as Arp 320 in which another galaxy, PGC 36010 is part of it.[9]
This group was also observed by Paul Hickson, in which he included them inside his article which was published in 1982.[10] It is noted that this group is designated as Hickson 57. NGC 3751 is known as HCG 57F.[11]
