Gas+Planets

This is where you will put information and electronic presentation for the gas planets

-Gas planets are also referred to as gas giants, giant planets, and Jovian planets - Gas planets are said to have a rocky center - Jupiter, Saturn, Uranus, and Neptune - The gas giants in our Solar System are also called the outer planets because they are the four planets in the Solar System furthest from the Sun. - **Classic** gas giants and the **ice** giants - Jupiter is considered the model for traditional gas giants - While ice giants do have some hydrogen and helium, they are mostly made up of “ices” such as methane, ammonia, and water - Uranus and Neptune are the two ice giants in our Solar System - All of Solar System’s gas planets have planetary ring systems and many moons - Because the gas giants are composed of gas, they are less dense than the terrestrial planets Uranus is the seventh planet from the sun and is named after the Greek God of the sky in latin. It is the only planet whose name came from a figure in Greek mythology as opposed to Roman mythology. [] 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 was first visited by Pioneer 10 in 1973 and later by Pioneer 11, Voyager 1, Voyager 2 and Ulysses. The spacecraft Galileo orbited Jupiter for eight years. It is still regularly observed by the Hubble Space Telescope. Jupiter is about 90% hydrogen and 10% helium (by numbers of atoms, 75/25% by mass) with traces of methane, water, ammonia and "rock". This is very close to the composition of the primordial Solar Nebula from which the entire solar system was formed. Jupiter Jupiter is the largest planet in our Solar System. Ancient Astronomers named Jupiter after the king of the Roman Gods. Jupiter is the 5th closest planet to our sun. The atmosphere of Jupiter consists of about 84 percent Hydrogen and about 15 percent helium, with small amounts of acetylene, ammonia, ethane, methane, phosphine, and water vapor. With four large moons and many smaller moons it forms a kind of miniature solar system. In fact, Jupiter resembles a star in composition, and if it had been about 80 times more massive, it would have become a star rather than a planet. [] Jupiter is out of question already because of high gravity and strong radiation. While other such planets have more or less Earth gravity. Uranus and Neptune seems to have methane at cloudtops, which is heavier than our air . If you weigh 100 pounds on Earth, you would weigh 264 pounds on Jupiter. Jupiter has a mass 318 times greater than the Earth's and a diameter that is 11 times larger. The mass of Jupiter is 70% of the total mass of all the other planets in our Solar System. Jupiter's volume is large enough to contain 1,300 planets the size of Earth. Jupiter rotates faster than any planet in the Solar System. It rotates so quickly that the days are only 10 hours long... But it takes 12 Earth years for Jupiter to complete an orbit around the sun. The great red spot on Jupiter is a storm that has been going on for over 300 years. You can fit 100 Earths into Jupiter's great red spot. Jupiter has the biggest moon in the Solar System, Ganymede. It is even bigger than Mercury and Pluto. Jupiter has a ring just like Saturn and Uranus. The Planet has over 60 known satellites (moons) but most of them are extremely small and faint. Jupiter is covered by an ocean of hydrogen with a sludge-like consistency. Unlike other planets, Jupiter sends out a strong radio radiation that can be detected on Earth. In 1994, pieces of a comet called shoemaker-Levy 9 broke apart and crashed into Jupiter. This left patches in Jupiter's atmosphere that lasted for many months
 * Jupiter Facts You Might Not Know About**
 * NEPTUNE**
 * Neptune is the eighth planet from the sun which is the farthest from the sun.
 * It is the fourth-largest planet by diameter and the third largest by mass, which is roughly around 17 times the mass of Earth.
 * It is also known as the Great blue Planet, because of its appearance which is all blue.
 * It was discovered in 1846 by using mathematical prediction.
 * Neptune has been visited by only one spacecraft, Voyager 2, which flew by the planet on August 25, 1989.
 * Neptune's atmosphere is composed primarily of hydrogen and helium, along with traces of Methane and other hydrocarbons.
 * Astronomers sometimes categorize Neptune as an “ice giant” along with Uranus, in order to distinguish them from Saturn and Jupiter.


 * The interior of Neptune is made up of ice and rocks.
 * Neptune's atmosphere is noted for its active and visible weather patterns.
 * When the Voyager 2 flew by it found The Great Dark Spot, which is an anticyclonic storm the size of earth.
 * These weather patterns are driven by the strongest sustained winds of any planet in the Solar System, with recorded wind speeds as high as 2,100 km/h.
 * Neptune's outer atmosphere is one of the coldest places in the Solar System, with temperatures at its cloud tops approaching -218 °C.
 * While temperatures at the center of the planet are roughly 5,000 degrees Celsius.
 * Neptune has a faint and fragmented ring system that was confirmed on the Voyager 2 flyby.
 * In Roman Mythology Neptune is the god of the seamedia type="custom" key="10997770"
