This post is a list of the largest known objects in the universe. The observable universe has a diameter of 93 billion light years (ly). The actual size of the universe is unknown. The picture above has some of the largest known superclusters, but is only a fraction of the observable universe. Our home supercluster, Laniakea is shown in yellow (520 million ly across).
