Arp 78 is a disturbed spiral galaxy located in the
constellation of Aries.
It is receeding with 2500 km/s which corresponds to a distance of about
100 million lightyears (assuming H0=75 km/s/Mpc).
The galaxy contains a bar and a dwarf seyfert nucleus with ongoing star formation.
There are a lot of dwarf galaxies visible in the immediate neighbourhood of the galaxy.
They might be interacting with Arp 78, the bright dwarf elliptical galaxy on top of Arp 78
beeing responsible for the tidal arm leading towards the lower right and the weaker tidal arm
to the upper left. (See High Contrast Version!)
