NGC 3753 is a large spiral galaxy with a bar[1] located in the Leo constellation.[2] It is located 435 million light-years away from the Solar System[3] and was discovered on February 9, 1874, by Ralph Copeland.[4]
NGC 3753 is classified as a LINER galaxy meaning, it presents an emission spectrum characterized by broad lines of weak ionized atoms. It also has a luminosity class of I-II.[3]

NGC 3753 is a member of the Copeland Septet which consists of 7 galaxies discovered by Copeland in 1874.[5] The other members are NGC 3746, NGC 3745, NGC 3748, NGC 3750, NGC 3751 and NGC 3754.[6]
Halton Arp noticed the 7 galaxies in the group, in which he published the article in 1966.[7] The group is designated as Arp 320 along another galaxy, PGC 36010.[8]
This group was observed by Paul Hickson in which he included them in his article in 1982.[9] The group is known as Hickson 57 in which NGC 3753 is the dominant member.[10]
