NGC 4070 is also classified as a
LINER galaxy.[12]
Physical characteristics
Deep images obtained with the CAFOS instrument at the
Calar Alto Observatory reveal that NGC 4070 has some deviation from a perfectly spherical or ellipsoidal shape morphology. This indicates that NGC 4070 has undergone a recent
interaction, either with the galaxy
2MASX J12040831+2023280 or with a small knot of material. There also appears to be a faint, broad bridge of luminous matter between NGC 4070 and the neighbouring elliptical galaxy
NGC 4066. The two galaxies are separated by a projected distance of 370,000
ly (114
kpc).[13]
