Abell 2029 or A2029 is a large cluster of galaxies 315 megaparsecs (1,027 megalight-years) away in the constellation Virgo. A2029 is the definition of a Bautz-Morgan classification I cluster due to its central galaxy, IC 1101. IC 1101 is perhaps the largest galaxy known, with estimates ranging from 5.6 to over 6 million light years across; contrast this with the Milky Way, which is 100,000 light years across. A2029 is also about 81 times bigger than the Milky Way, with a luminosity of 2×1012 L☉, as announced in July, 1990, by Juan M. Uson, Stephen P. Boughn, and Jeffrey R. Kuhn. This type of galaxy is called a cD-type brightest cluster galaxy and may have grown to its large size by accreting nearby galaxies.
