: The recessional velocity of PGC 28757 is only 45 km/sec, far too small in comparison to peculiar (non-Hubble expansion) velocities to be of any use in determining its distance. Redshift-independent distance estimates range from 8.5 to 32.5 million light years, with the most commonly accepted value being 11 to 12 million light years, as it is believed to be a satellite of approximately 12 million light year distant NGC 3031 (= M81). Given that and its apparent size of ? arcmin, the galaxy is about ? thousand light years across. It is believed that most of the stars in the dwarf galaxy (and the galaxy itself) were created as a result of a close encounter between M81, M82
and NGC 3077
between 200 and 300 million years ago. That interaction tore some one of the older stars from one or more of the galaxies and triggered a wave of intense star formation that resulted in most of the stars now visible in PGC 28757, and is still continuing in the region between it and M81 at a slower rate, as evidenced by a "bluish fuzz" in the region near the two galaxies, which consists of newly formed stars, but too few of them to be easily imaged.
