'''Abell 2029''' or '''A2029''' is a large  and relaxed [[galaxy cluster|cluster]] of [[galaxy|galaxies]] 315 [[Parsec#Megaparsecs and gigaparsecs|megaparsecs]] (1.027 billion [[light-year]]s) away in the constellation [[Virgo (constellation)|Virgo]].<ref>Chandra X-ray Observatory, [http://chandra.harvard.edu/photo/2004/darkenergy/ "Galaxy Clusters and Dark Energy: Chandra Opens New Line of Investigation on Dark Energy"], '''Harvard-Smithsonian Center for Astrophysics'''</ref> A2029 is a [[Bautz–Morgan classification]] type I cluster due to its large central galaxy, [[IC 1101]]. Abell 2029 has a diameter of 5.8–8 million light-years. This type of galaxy is called a [[Type-cD galaxy|cD-type]] [[brightest cluster galaxy]] and may have grown to its large size by accreting nearby galaxies. Despite its relaxed state, it is the central member of a large supercluster which shows clear signs of interaction.
