Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a giant planet with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined. Jupiter is a gas giant, along with Saturn. (Uranus and Neptune are ice giants.) Jupiter was known to astronomers of ancient times. The Romans named it after their god Jupiter. When viewed from Earth, Jupiter can reach an apparent magnitude of −2.94, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky after the Moon and Venus.
Jupiter is primarily composed of hydrogen with a quarter of its mass being helium, though helium comprises only about a tenth of the number of molecules. It may also have a rocky core of heavier elements, but like the other giant planets, Jupiter lacks a well-defined solid surface. Because of its rapid rotation, the planet's shape is that of an oblate spheroid (it has 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 17th century when it was first seen by telescope. Surrounding Jupiter is a faint planetary ring system and a powerful magnetosphere. Jupiter has at least 67 moons, including the four large Galilean moons discovered by Galileo Galilei in 1610. Ganymede, the largest of these, has a diameter greater than that of the planet Mercury.
The PGM-19 Jupiter was a intermediate-range ballistic missile (IRBM) of the United States Air Force, removed from service by April 1963. It was a liquid-fueled (LOX and RP-1) rocket, with one engine producing 667 kN of thrust.

The PGM-19 Jupiter was the first nuclear tipped, medium-range ballistic missile of the United States Air Force .It was a liquid-propellant rocket using RP-1 fuel and LOX oxidizer, with a single Rocketdyne LR70-NA rocket engine producing 667 kN of thrust.It was armed with the 1.1 megaton W49 nuclear warhead.The prime contractor was the Chrysler Corporation. ---Image-Copyright-and-Permission--- About the author(s): U.S. government License: Public domain ---Image-Copyright-and-Permission--- This channel is dedicated to make Wikipedia, one of the biggest knowledge databases in the world available to people with limited vision.

The first launch attempt of a Jupiter Missile at Cape Canaveral, Florida on March 1, 1957. The launch at first appeared to be successful, however 72 seconds into the flight the missile lost control and subsequently exploded. The PGM-19 "Jupiter" was a Medium Range Ballistic Missile (MRBM) developed by the United States Army during the mid 1950's, and was capable of delivering the "W49" 1.45 Mt Thermonuclear warhead 1500 miles from the launch site. . .

3-minute film on the first successful flight of JUPITER, 31 May 1957 The PGM-19 Jupiter was a medium-range ballistic missile (MRBM) of the United States Air Force, removed from service by April 1963. It was a liquid-fueled (LOX and RP-1) rocket, with one engine producing 667 kN of thrust. Jupiter was America's second MRBM design, the first being Thor. Jupiter later served as a satellite launch vehicle. http://en.wikipedia.org/wiki/Jupiter_missile Creative Commons license: Public Domain http://creativecommons.org/licenses/publicdomain/
