The constellation of Aries is not noted for its deep sky objects, but it does contain a handful of small and faint groups of galaxies - small and faint, that is, from the point of view of an observer on Earth. IC 1797 is one of these, a galaxy of barred spiral form with a visual magnitude of just +15.25.
IC 1797 is far from the Milky Way Galaxy, at a distance of approximately 170 million light years (that is, nearly a hundred times more distant than the Andromeda Galaxy) and receding at a velocity of some 3,900 km/s. This is a spiral galaxy whose arms are arranged in a barred structure, but those arms are faint and diffuse in comparison with its central core.
