A recent study by James Elsner and Thomas Jagger of Florida State University linked hurricane intensity to the number of these objects. Variations in these objects are predicted by Sporer's law. Their numbers fell drastically between 1645 and 1715, which is known as the Maunder Minimum; however, their numbers generally wax and wane over an 11-year period. For 10 points, name these cool dark objects that are found on the surface of their namesake object, which is located at the center of our Solar System.
