Which is the largest planet in the solar system?

Jupiter is the giant of our solar system, with an equatorial diameter of about 143,000 kilometers — you could line up more than 11 Earths across its face. Its mass is more than 2.5 times that of all the other planets combined. Jupiter is a gas giant made mostly of hydrogen and helium, with no solid surface, and it spins so fast that a day there lasts under 10 hours. Its most famous feature is the Great Red Spot, a storm larger than Earth that has raged for centuries. Jupiter also has at least 95 known moons, including Ganymede, the largest moon in the solar system.
