NGC 7640 is a barred spiral galaxy located in the constellation Andromeda, approximately 30 million light-years away from Earth. This galaxy, classified as an SB(s)c type, features loosely wound spiral arms with a central bar structure, indicating a late-stage spiral morphology with less defined, more irregular arms compared to other spiral galaxies. 

NGC 7640 is noted for its interactions with neighboring galaxies, which have likely influenced its structure and led to regions of active star formation.
