Abell 2255 (often shortened to A2255) is a rich galaxy cluster containing some 300-500 galaxies located at a relatively nearby distance of redshift z=0.08. It has a radius that spans 16.3 million light years. X-ray observations of Abell 2255 indicate that it had recently gone through a merger event with another galaxy cluster around 0.15 billion years ago based on XMM-newton observatory observations of temperature asymmetries of its intracluster medium (ICM).
