What's the Biggest Planet in Our Solar System? In order to figure out how heavy a planet is, scientists need to know two things: how long it takes nearby objects to orbit the planet and how far away those objects are from the planet. The planets beyond our solar system are called "exoplanets," and they come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth or Mars. NASA, "Mercury: Solar System Exploration," January 2022. There are 3 planets in the TRAPPIST-1 system that sit in the habitable zone of its central star TRAPPIST-1 e, f and g. The habitable zone is the distance from the star whereby liquid water could exist on the planet's surface. The orbit volumes of Earth and Pluto are very close; Pluto has the larger volume because its enormous distance from the Sun outweighs its much smaller size. IX.
