NGC 3753 is a large barred spiral galaxy located in the Leo constellation. [1] It is located 435 million light-years away from the earth [2] and was discovered on February 9, 1874, by Ralph Copeland. [3]

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. [2] NGC 3753 is viewed edge-on. The edge-on view is the reason why we see a dust lane in NGC 3753.

NGC 3753 is a member of the Copeland Septet which consists of 7 galaxies discovered by Copeland in 1874. [4] The other members are NGC 3746, NGC 3745, NGC 3748, NGC 3750, NGC 3751 and NGC 3754. [5]

Halton Arp noticed the 7 galaxies in the group, in which he published the article in 1966. [6] The group is designated as Arp 320 along another galaxy, PGC 36010. [7]

This group was observed by Paul Hickson in which he included them in his article in 1982. [8] The group is known as Hickson 57 in which NGC 3753 is the dominant member. [9]
