DescriptionMoons vs time.SVG	English: Plot of the number of moons discovered in a year vs. the year number, up to 2025, using the discovery years given in wikipedia's list of natural satellites. The first peak at 1980 was caused by Voyager 1; the second at 1986 caused by Voyager 2. The peaks in recent times are caused by improvements to ground- and Earth orbit-based optical telescopes. Note: This is different from the announcement date, for which there is a separate plot linked below.
