The two stars are completely unrelated to each other, with the whiter, dimmer star (2MASS J00084563+2350186[4]) being at a distance of 10400+4400
−2400 light years,^{[citation needed]} and the yellower, brighter star (2MASS J00084521+2350184[5]) having a minimum distance of 215,000 light years.^{[citation needed]} While both stars are technically outside the milky way's galactic disc, the nearer is 6400±2100 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 the Milky Way itself, being at least 220,000 light-years from the galactic core.^{[citation needed]}
