The unit of measurement … It’s around 650 million light-years away. Our own supercluster, Laniakea, consists of approximately 100,000 galaxies, more than 10 times richer than the largest known clusters. Yet these superclusters only appear to be structures. The Saraswati supercluster is about 4 billion light years away in the constellation Pisces, much more distant than other superclusters we have seen. The Vela supercluste r (VSC) – (larger ellipse). The largest object in our Solar System is the Sun. Celestial bodies bigger than the supercluster: The size of celestial bodies is measured by its dimensions in light years. First, the Virgo Supercluster is our supercluster, meaning that it tends to matter for much the same reason that our solar system matters. This is a list of the largest cosmic structures so far discovered. The most famous, the Shapley Supercluster, for example, is thought to be the largest of its kind in our corner of the cosmos.
However, since a supercluster is a much, much bigger structure than a solar system, that robs much of the strength of this sentiment. The largest supercluster is possibly the Horologium Supercluster The largest galaxy is IC 1101 The largest star is VY Canis Majoris.
