Nano‐Saturns consisting of macrocyclic rings and fullerene spheres can be constructed from various types of rings via weak molecular interactions. Structures and association energies of the supramolecular Saturn systems have been studied by experimental and theoretical methods. Successful ring hosts should have a cavity that fits to the size and shape of spherical guests. In particular, disk‐shaped rings are attractive hosts to mimic the Saturn shape precisely. A few examples are introduced by S. Toyota and E. Tsurumaki in their Minireview on page 6878 ff.
