NGC 8
NGC 8 is an asterism of two completely unrelated stars in the constellation Pegasus, discovered on 29 September 1865 by Otto Wilhelm von Struve. It is approximately 2.7 arc minutes away from NGC 9.
The two stars are completely unrelated to each other, with the whiter, dimmer star being at a distance of light years, and the yellower, brighter star having a minimum distance of 215,000 light years. While both stars are technically outside of the milky way's galactic disc, the nearer is light-years south of the 1,000-light-year-thick disc, and the further is not only at least 130,000 light-years south of the disk, but is located entirely outside of the Milky Way itself, being at least 220,000 light-years from the galactic core.
