At a distance of about 100 million light-years (30 megaparsecs), NGC 5422 is located within the sparse NGC 5485 group, which is dominated by lenticular galaxies.[3] It has only a single, thick, disk component. Like other galaxies in the group, it has no recent star formation, as its stellar disk is relatively old (about 10 billion years old). Its disk appears similar to the face-on galaxy NGC 6340, but appears edge-on.[3]
