Observations from the Ground confirmed that the stars in Ant 2 move the related group, is not converging with our Galaxy closer than 40 kiloparsec (130 thousand light years). Like many other dwarf galaxies, Ant 2 – quite old, and most of its stars are old, small and with a low metallicity (content of elements heavier than helium).
