Our solar system is home to a wide diversity of planetary bodies, boasting eight planets, five officially recognized dwarf planets, and almost 1,000 confirmed moons. The eight planets consist of the four rocky (terrestrial) planets of the inner solar system and the four gas giant planets of the outer solar system. The largest planet in our solar system is Jupiter, measuring a radius and mass of 11 and 318 times of Earth, respectively. However, the discovery of exoplanets quickly altered our understanding of planetary sizes, as several have been discovered to have masses and radii several times that of Jupiter. So, how big can planet get, and are there limits to their sizes?
