Biggest Planet in Milky Way Galaxy

Do you know what is Jupiter ? Ya, Jupiter is a planet too in our solar system. Jupiter is the fifth planet from the center of our solar system, Sun. The size of this planet is the biggest one in our solar system, two times mass of the other planet. Jupiter is primarily composed of hydrogen with a quarter of its mass being helium, although helium only comprises about a tenth of the number of molecules.

Jupiter takes only 9 hours and 55 minutes to spin on its axis. This means a day on Jupiter is less than 10 hours long. Its fast rotation causes the planet to be squashed, being wider at the equator than from North to South. Jupiter's moon, Ganymede, is the biggest moon in the Solar System. Jupiter's gravity is used to catapult space-craft on deep space missions further away. This is how the Voyager missions of 1975 managed to succeed.
