PGC 34176 (= Leo II)
A 12th-magnitude elliptical galaxy (type dE0) in
Leo (RA 11 13 28.8, Dec +22 09 06)
Physical Information: PGC 34176's recessional velocity of 80 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 660 thousand to 760 thousand light years, with the most generally accepted value being just under 700 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. Its position in Leo has led to its designation as Leo II (another similar galaxy in the same general area being called Leo I). Given its presumed distance and apparent size by 12.0 by 11.0 arcmin, Leo II 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.

PGC 34476
A magnitude 16.5(?) irregular galaxy (type Im?) in
Leo (RA 11 17 27.6, Dec +04 36 16)
Physical Information: Based on a recessional velocity of 1755 km/sec, PGC 34476 is 80 to 85 million light years away. Given that and its apparent size of about 0.95 by 0.2 arcmin, it is 20 to 25 thousand light years across. The galaxy's image is heavily obscured by glare from the magnitude 10.6 star BD+05 2473; if its image could be separated from that of the star, it might be classified differently, and its apparent size significantly adjusted.
