NGC 5291 is an elliptical galaxy about 190 million light-years away that interacts with a smaller, highly deformed galaxy nicknamed "the Seashell" . NGC 5291 lies on the western outskirts of Abell 3574 and is possibly a member of this galaxy cluster.
The galaxy was first identified by Longmore et al. examined in more detail in a study published in 1979. The nickname “the Seashell” for the interacting galaxy, which seems to fly past NGC 5291 at a large speed difference, goes back to them.
NGC 5291 was discovered by the British astronomer John Herschel on May 8, 1834 .
