It is possible for large clusters, such as galaxy clusters, to have a mass over a thousand times that of our Milky Way Galaxy, which has a mass of approximately 1 trillion times that of the Sun. It is possible for clusters of galaxies to have a mass over a thousand times greater than our own Milky Way galaxy. The largest known galaxy cluster, the El Gordo cluster, has an estimated mass of around 3 quadrillion times that of the sun, which is much larger than our entire galaxy.
