It is classified as a Seyfert galaxy and as a LINER galaxy. It also has a prominent, extended dust lane.
Physical characteristics
The disk of NGC 4302 contains extraplanar dust that is organized into filamentary structures and large dust complexes. The apparent bending of many of the large complexes toward the north of the galaxy appears to be due to an interaction with the intracluster medium caused by the motion of NGC 4302 as it falls into the Virgo Cluster.
The dense, dusty matter in the disk of NGC 4302 appears to be largely tracing matter ejected from the disk by energetic feedback from massive stars.
First detected by Pildis et al., NGC 4302 has a faint but prominent layer of extraplanar diffuse ionized gas (DIG) that extends out to a galactocentric radius of ~13,000ly (4kpc) and a height of ~6,500ly (2kpc) above the plane of the galaxy.
The presence of a boxy/peanut bulge in NGC 4302 suggests that the galaxy contains a thickened bar that is viewed edge-on.
HI Disk
The HI disk of NGC 4302 is truncated to within the optical disk to the south of the galaxy. This truncation appears to be the result of ram pressure.
Tidal Bridge
Kantharia et al. and Zschaechner et al. both independently detected a tidal bridge between NGC 4302 and NGC 4298. The bridge is the result of a tidal interaction between the two galaxies.

HI tail
First identified by Chung et al., NGC 4302 has a ~52,000ly (16kpc) tail of neutral atomic hydrogen (HI) that extends to the north of the galaxy. The tail appears to be a result of ram pressure or by a tidal interaction with NGC 4298. However, NGC 4302 appears relatively undisturbed favoring the cause of the tail to be due to ram pressure.
The HI tail is pointed away from M87 which suggests that NGC 4302 is falling into the center of the Virgo Cluster on a highly radial orbit.
