While both stars are technically outside of the milky way's galactic disc, the nearer is {{val|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 of the Milky Way itself, being at least 220,000 light-years from the galactic core.
