A galaxy cluster is a group of galaxies that are gravitationally bound to each other. They are the largest known gravitationally bound structures in the universe. They typically contain hundreds to thousands of galaxies and have a typical size of 2 to 10 million light-years. Galaxy clusters are not evenly distributed throughout the universe; they are found in filaments and walls that make up the large-scale structure of the universe.

Superclusters, on the other hand, are groups of galaxy clusters that are gravitationally bound to each other. They are among the largest structures in the universe, spanning up to 200 million light-years. They are also not evenly distributed throughout the universe, but are found in the same filaments and walls as galaxy clusters.

So, the main difference between superclusters and galaxy clusters is their size and the fact that superclusters are made up of multiple galaxy clusters.
