= Planetary systems by number of confirmed planets
{wiki=Category: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.
