Planetary systems by number of confirmed planets

ID: planetary-systems-by-number-of-confirmed-planets

As of my last update, the number of confirmed planets in planetary systems can vary greatly from one system to another. For instance, our Solar System has eight confirmed planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Exoplanetary systems discovered outside our Solar System can have a wide range of planet counts. Some systems have been found with just one confirmed planet, while others host more than 10 or even 20 confirmed planets.
