The largest planet in our solar system is Jupiter. It has a diameter of about 142,984 kilometers (88,846 miles), which is roughly 11 times the diameter of Earth. Jupiter's volume is large enough to fit approximately 1,300 Earths inside it. It has a mass about 318 times that of Earth, making it by far the most massive planet in the solar system. Jupiter is a gas giant composed primarily of hydrogen and helium and has more than 90 known moons, with a very strong gravitational influence on other objects in the solar system.
