If a distance of 1.57 kiloparsecs
is used for NGC 6210 then the absolute magnitudes of this object are: -1.28, -1.90, -1.32 and -0.63 for the B, V, R and I filters respectively.
Remarkably, the dense, star-forming gas of the galaxy is greatly offset from the hydrogen gas originally revealed by the quasar spectrum (by approximately 100,000 light years or 30 kiloparsecs
Based on a count of the planetary nebulae within 2 kiloparsecs
(6,500 light-years) of the Sun, they extrapolate that the Milky Way's population includes anywhere from 11,000 to 28,000.
This led to the discovery of two tidal streams to the northwest (streams E and F) at projected distances of 60 and 100 kiloparsecs
(200,000 and 300,000 light years) from Andromeda's center.
