1. JUPITER
A Gaseous planet

2. History
Jupiter was discovered by Galileo.
Galileo was the first astronomer to detail extensive observations about the planet. He was also the first astronomer to discover the four largest moons that orbit the planet.
Galileo began seriously observing the planet in 160This discovery of Jupiter’s moons occurred on January 7, 1610.

3. Solar system
Jupiter is the fifth planet from the Sun and by far the largest.
Jupiter is more than twice as massive as all the other planets combined (the mass of Jupiter is 318 times that of Earth).
Jupiter orbit period is 12 years.

4. Measurements of Jupiter
The mass of Jupiter is 1.9 x 1027 kg. It has an equatorial diameter of 143,000 km. The Jovian volume is 1.43 x 1015km3
It’s density is so low that it would float on water.
The planet is located about 1,400 light-years away, and orbits its host star every 3.5 days. It orbits 7.2 million km from its star, reaching a temperature of 1,600 Kelvin.

5. Composition & Atmosphere
When we look at Jupiter, we are seeing icy clouds of gases moving at high speeds in the atmosphere. Jupiter's atmosphere is composed of about 90% hydrogen and 10 % helium. There are only minute traces (0.07%) of methane (CH3), water, ammonia, and rock dust.

6. Jupiter Surface Conditions
Jupiter's temperature is 190 degrees Fahrenheit or degrees Celsius for the visible surface of the atmosphere, to 9°F (-13°C) at lower cloud levels. Certain regions reach as high as 40°F (4°C) at still lower cloud levels near the equator. Jupiter gives off four times as much heat as it gets from the sun.
The Great Red Spot is a great anti-cyclonic (high pressure) storm akin to a hurricane on Earth. Its so big, that 3 earths could fit inside of its boundaries. Humans also observed “the spot” by using telescopes.

7. Jupiter Big 4 Ganymede Callisto Io Europa
Jupiter has about 67 known moons , but the 4 largest is, Ganymede, Io, Europa, and Callisto.

8. Ganymede Ganymede is actually the largest moon in the solar system.
Its gravity:1.428 m/s.
Distance to Earth: 390,400,000 miles.
Its orbital period: 172 hours.
Circumference: 10,273 miles.
Orbits: Jupiter
It has a ocean beneath its thick icy crust.
Ganymede is about 3,273 miles (5,268 kilometers) across.
The Galileo probe measured Ganymede's magnetic field in 2002, providing some data supporting the theory that the moon has an ocean.

9. Jupiter Rings
Jupiter has faint, dark, narrow rings composed of tiny rock fragments and dust. They do not contain ice, like Saturn's rings. Jupiter's rings are continuously losing material.
The 3 Rings
The Halo ring is a faint, wide ring that has the shape of a doughnut. It is about 22,800 wide and is about 20,000 km thick. This ring starts at 100,000 km from the center of Jupiter; the outer edge of the Halo merges into the Main ring.
The Main ring is 6,400 km wide an less than 30 km thick. This very thin ring has a mass of about kg. The ring is about 7,000 km wide; it starts at 122,800 km from the center of Jupiter and has an abrupt outer edge 129,130 km from the center of Jupiter.
The Gossamer ring is a very faint and very wide ring. It consists of two rings, one embedded within the other. It is composed of very tiny particles, the microscopic debris from the moons, Amalthea and Thebe. The Gossamer ring starts at 129,000 km from the center of Jupiter and extends beyond the orbit of the moon Amalthea.

10. Exploration
The planet Jupiter's four largest moons are called the Galilean satellites, after Italian astronomer Galileo Galilei, who observed them in 1610.
Pioneers 10 and 11 (1973 to 1974) and Voyager 1 and Voyager 2 (1979) offered striking color views and global perspectives from their flybys of the Jupiter system. From 1995 to 2003, the Galileo spacecraft made observations from repeated elliptical orbits around Jupiter, passing as low as 261 km (162 miles) over the surfaces of the Galilean moons.
