Jupiter (IPA: [ËdÊu.pÉ.tÉ], IPA: [ËdÊu.pɪ.tÉ]) is the fifth planet from the Sun and the largest planet within the solar system. It is two and a half times as massive as all of the other planets in our solar system combined. Jupiter, along with Saturn, Uranus, and Neptune, is classified as a gas giant. Together, these four planets are sometimes referred to as the Jovian planets—Jovian being the adjectival form of Jupiter.
When viewed from Earth, Jupiter can reach an apparent magnitude of -2.8, making it the fourth brightest object in the night sky. The planet was known by astronomers of ancient times and was associated with the mythology and religious beliefs of many cultures. The Romans named it after Jupiter, the principal God of Roman mythology, whose name is a reduction of 'Deus Pater', meaning 'God father'.[5]
The planet Jupiter is primarily composed of hydrogen with only a small proportion of helium; it may also have a rocky core of heavier elements. Because of its rapid rotation the planet is an oblate spheroid (it possesses a slight but noticeable bulge around the equator). The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. A prominent result is the Great Red Spot, a giant storm that is known to have existed since at least the seventeenth century. Surrounding the planet is a faint planetary ring system and a powerful magnetosphere. There are also at least 63 moons, including the four large moons called the Galilean moons that were first discovered by Galileo Galilei in 1610. The largest of these moons is bigger than the planet Mercury.
Jupiter has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Voyager fly-by missions and later by the Galileo orbiter. Future targets for exploration include the possible ice-covered liquid ocean on the Jovian moon Europa

The planet, dubbed HAT-P-1, is located some 450 light-years from Earth in the constellation Lacerta. It is the largest planet ever discovered and boasts a radius nearly 1.4 times larger than Jupiter's. HAT-P-1 is also the least dense of all known planets. But if you mean in our Solar System, then yes the answer is Jupiter.

Jupiter (planet), fifth planet from the Sun, and the largest in the solar system. Named after the ruler of the gods in Roman mythology, Jupiter has 1,400 times the volume of the Earth, but is only 318 times as massive. The mean density of Jupiter is therefore only about one quarter that of the Earth, indicating that the giant planet must consist of gas rather than the metals and rocks of which the Earth and the other inner planets are composed.
Jupiter and its Moons Jupiter is the largest of the planets, with a volume 1,400 times that of the earth. The bands of colour are cloud belts, revealing strong atmospheric currents. The massive planet, upper right, is with the four largest of its satellites: Europa, centre, Io upper left, Callisto lower left, and Ganymede lower right.
Comet Bombardment of Jupiter, 1994 Fragments of Comet Shoemaker-Levy 9 collided with Jupiter between July 16 and July 22, 1994, stirring up the planet’s atmosphere and enabling scientists on the earth to gain a rare glimpse of the planet’s interior. The comet had broken into 21 large fragments on July 8, 1992, when it ventured too close to Jupiter. Trapped by Jupiter’s strong gravitational pull, these fragments bombarded the planet at speeds of about 210,000 km/h (130,000 mph). This image, taken by the National Aeronautics and Space Administration’s Hubble Space Telescope, reveals the impact sites (dark spots near the centre of the image) created by two of the comet fragments.Space Telescope Science Institute

Orbiting the Sun at a mean distance 5.2 times as great as that of Earth, Jupiter makes a complete revolution in 11.9 years. It takes only 9.9 hours to rotate once on its axis. This rapid rotation causes an equatorial bulge that is apparent even in telescopic views of the planet. The rotation is not uniform. The banded appearance of Jupiter’s belts is due to the presence of strong atmospheric currents, reflecting the different rotation periods at different latitudes. These belts are made more apparent by the pastel colours of the clouds. These colours are also apparent in the famous brownish-red oval called the Great Red Spot. The colours come from traces of compounds formed by ultraviolet light, lightning discharges, and heat. Some of these compounds may be similar to the organic molecules that formed on the ancient Earth as a prelude to the origin of life.

Jupiter is so large that all of the other planets in the solar system could fit inside of it
Jupiter is a large gas planet whose clouds change colors daily. This planet is made mostly of hydrogen and helium gases. Jupiter gives off two times more heat than it gets from the Sun. It shines very brightly in the night sky for nine months of the year when it is closest to Earth. Huge areas of swirling gases can be found in Jupiter's atmosphere. The largest swirling area of gas is called the Great Red Spot. Scientists believe this is a large hurricane-like storm which has lasted for hundreds of years. Large bolts of lightning have also been seen in Jupiter's atmosphere. Pictures taken by space probes have shown thin rings around Jupiter. Jupiter has forty-eight named moons (and may have as many as 63!). One of Jupiter's moons, Io, has active volcanoes on it. Areas on Io that are near the volcanoes are very, very hot.
