NGC 4402 is a relatively near, edge-on spiral galaxy located around 50 million light-years from Earth.

NGC 4402 is roughly 55 thousand light-years wide and is moving away from Earth at around 232 kilometers per second.

GALEX observations of the galaxy do not appear to show trailing gas, dust and star formation streamers extending from the disc, indicating that the galaxy has likely begun to feel the effects of the ram pressure stripping only recently.

NGC 4402 will likely lose a significant fraction of its star formation material to this process, rendering it an anemic galaxy.

One supernova has been observed in NGC 4402 : SN 1976B (type unknown, mag.
