Object name: ARP163
Designation(s): ARP163, NGC4673,
Arp 163/Haro 09/NGC 4670 is an SB(s)0/a pec: BCDG galaxy in Coma Berenices. BCDG means Blue Compact Dwarf Galaxy. If the distance is 60 million light-years as its redshift and a couple other sources indicate then it is about 27 thousand light-years in size. Some sources put it only 36 million light-years away which cuts it down to 16 thousand light-years which certainly is a dwarf galaxy. Arp put it in his class of "galaxies with diffuse filaments, diffuse counter-tails." He left no comment about it. I can't see either filaments or a counter tail. Today it is thought to be rapidly forming stars but not at the starburst level. Still sufficient to color the galaxy blue due to the massive and thus bright blue stars it is making which cover up the far more common but much fainter main population of red stars.
