Image of Epsilon Arietis

Close inspection of Epsilon Arietis reveals that it is actually a binary system: two white stars of similar mass and luminosity follow long slow orbits around one another.

The white light of this massive star is dimmed somewhat by its great distance: more than 300 light years from the Earth. Nonetheless, it is luminous enough to be visible to the naked eye.
