The Peekaboo Galaxy (officially known as HIPASS J1131-31 and PGC 5060432) is an irregular compact blue (suggesting hot young stars) dwarf galaxy in the constellation Hydra.[3] The galaxy is relatively small, at about 1,200 light-years (0.00037 Mpc) across. It is also relatively nearby, at a distance of around 22 million light-years (6.7 Mpc) from Earth.[2] The Peekaboo Galaxy is considered one of the most metal-poor ("extremely metal-poor" (XMP)), least chemically enriched, and seemingly primordial, galaxies known.[1][2][5][6][7][8][9][10]
