Which planet is the largest in our solar system?

Jupiter is the largest planet in our solar system — a gas giant whose mass is greater than all the other planets combined. Saturn is the second largest and is famous for its prominent rings. Earth and Mars are far smaller, rocky (terrestrial) planets. Basic astronomy facts like the order and relative sizes of the planets are part of Earth and space science. Jupiter's enormous size and its many moons make it a frequently referenced example; it is the giant of the solar system.
