: PGC 29488's recessional velocity of 285 km/sec is too small in comparison to peculiar (non-Hubble-expansion) velocities to be of any use for determining its distance, but redshift-independent distance estimates range from 650 thousand to 880 thousand light years, with the most generally accepted value being just over 800 thousand light yeas away. This makes it one of the more distant satellites of our own galaxy (for that reason it is briefly discussed on the page about Our Galaxy and its Satellites
), and definitely a member of our Local Group. It is a dwarf spheroidal (elliptical galaxy), and between its small size and distance, appears almost more like a loose collection of stars than a galaxy (it is also difficult to see because it is close to the first-magnitude star Regulus). Its position in Leo has led to its designation as Leo I (another similar galaxy in the same general area being called Leo II
). Given its presumed distance and apparent size by 9.8 by 7.4 arcmin, Leo I is almost certainly less than 2500 light years across. Used by the de Vaucouleurs Atlas of Galaxy Types
as an example of galaxy type dSph.
