Jupiter (IPA: [ˈdʒu.pə.tɚ], IPA: [ˈdʒu.pɪ.tə]) 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 third 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.

It's named after the Roman or Syrian God of War, Fertility, Air, and one of the Triad of high Gods. The other two are Mars and Quirinus. How they came up with it was by naming it after the God Jupiter. It was named about 2000 years ago. Jupiter was the King of the Gods in Roman mythology, making the name a good choice for what is by far the largest planet in our solar system.

The names we use today come from Greek Mythology. However, the names themselves are from the Latin version of the Greek gods.
Latins had their own gods. When Greek culture took over the Roman culture (in fact creating it by mixing latin and Greek cultures), the mythology of the Greek gods became associated with the latin gods.
Chronos was the father god (also father time -- hence chronometer for an instrument measuring time). Having been told that he would be shoved aside by one of his sons, he'd kill them all as soon as they were born. When Zeus was born, his mother -- tired of seing all her sons killed -- had him raised secretly on an island far away.
When Zeus was old enough, he fought his father and the Titans and won. He became the top god and his name was associated with the brightest planet in the night sky.
When the Greek culture was superimposed on the latin culture, Saturn became Chronos (but kept the name Saturn) and Iuppiter became Zeus. (Iuppiter became Jupiter after the letter J was created).
The planet known to Zeus by the Greeks got the name Jupiter under the Latin.
Later, as the scientists of our western civilization began writing about astronomy, they would do so in Latin. Therefore, they took the Latin names. That is why we ended up with
Mercury (Hermes, the winged messenger -- Mercury is the planet that moves the fastest)
Venus (Aphrodite) the most beautiful -- meaning the most brilliant (However, planet Venus never "dominates" the night sky; it is most of the time only in twilight).
Mars (Ares, god of war -- red is the color of blood, therefore war)
Jupiter (Zeus, chief god of the Pantheon) brightest planet that can "dominate" the sky (i.e., be in the sky at midnight)
Saturn (Chronos, father of Zeus)
and, later,
Uranus (Ouranos, father of Chronos)
Neptune (Poseidon, god of the sea -- because of the planet's color: turquoise like the south seas on Earth).

After the king of the gods Jove. Hence the term Jovian moons.
