Uranus: Helium And Oxygen

Neptune has 14 different moons. Neptune’s largest moon is called Triton. Triton is the only large moon in the solar system to orbit in the opposite direction to its planet’s rotation, this is known as a retrograde orbit. The distance of its orbit is 354,759 km. Its orbit period takes 5.9 days (retrograde). Triton was discovered by William Lassell. Neptune has 5 rings. Neptune is very cold compared to Earth. It is -214 degrees Celsius. Neptune is the smallest of the ice giants. Despite being smaller than Uranus, Neptune has a greater mass. Below its heavy atmosphere, Uranus is made of layers of hydrogen, helium, and methane gases. They enclose a layer of water, ammonia and methane ice. The inner core of the planet is made of

The rings made up of millions of ice crystals,some as big as house and others as small as specks of dust saturn is very light as it is made up of more hydrogen

This “Ice Giant” sure stands for its name as the 7th farthest planet from the Sun and its cold atmosphere brought about by the gases found here, hydrogen, helium and a little bit of methane. Uranus falls under the gas giant category along with neighbors Neptune and Saturn. This planet is composed of rock materials and various ices and is very similar to the cores of Saturn and Jupiter. Since the thick, blue-colored atmosphere covers the planet itself, scientists suggest that under the atmosphere is a hot, slushy ocean of water, ammonia, and methane thousands of mile deep right to a small, rocky core. Its blue color comes from the absorption of red light from the Sun by methane in the upper atmosphere but reflects blue light from the Sun back into space.

Being a large planet, Uranus' mass is the equivalent of 15 Earths and has a radius of 51,118 Kilometers. Uranus also has 13 rings made up of a frozen waterline material and dust. The planet’s rings are darker than Saturn's rings and have larger rocks within them. They are about 38,000 Kilometers away from the planet's core. The rings are tilted as well.

Uranus is a gas giant that is believed to have a solid core made of ice and rock. Astronomers now say it is possible for the surface to be covered with massive diamonds. The atmosphere of Uranus is primarily hydrogen and helium, but its beautiful colors come from the two percent of methane gas within its atmosphere. Uranus was once thought to only vary between shades of blue and green. These hues are why most early researchers believed that its surface was covered in oceans. Now, with help of the advancements in space vessels, we know that the color can be almost anywhere on the

Jupiter, Saturn, Uranus, and Neptune were formed by different types of rock and frozen materials (water, ammonia, and methane). These materials were once planetesmals, which formed from the rocky, metallic solid materials that were able to survive the collapse of the solar nebula which formed our solar system.

Uranus, the first planet discovered in modern times, was discovered by William Herschel while systematically searching the sky with his telescope on March 13, 1781. It had actually been seen many times before but ignored as simply another star (the earliest recorded sighting was in 1690 when John Flamsteed cataloged it as 34 Tauri). Herschel named it "the Georgium Sidus" (the Georgian Planet) in honor of his patron, the infamous (to Americans) King George III of England; others called it "Herschel". The name "Uranus" was first proposed by Bode in conformity with the other planetary names from classical mythology but didn't come into common use until 1850.

Before being known as a planet Uranus was mistaken for a star. Probably the first time that Uranus was observed was by Hipparchus of Nicaea. Hipparchus did mistaken Uranus for a star. Hipparchus may have recorded it as a star for his star catalogue that was later incorporated into Ptolemy's Almagest (1). William Herschel first observed Uranus on March 13, 1781 from the garden of his house at 19 New King Street in Bath, Somerset, England. Herschel "engaged in a series of observations on the parallax of the fixed stars." Using a telescope of his own design.

Storms and other atmospheric features are more easily seen on Neptune than on Uranus. This is due to Uranus’s absence of high-level clouds. Uranus has a low surface temperature and it is lacking any significant internal heat source so any clouds that are formed are only low-lying. Thus, any storms and atmospheric features are largely washed out by intervening stratospheric haze. Storms and other atmospheric features are easily seen on Neptune because its upper atmosphere is warmer than Uranus’s, and it has an internal energy source. Furthermore, astronomers believe that the combination of the less haze and extra heat from the internal energy source is what gives the greater visibility of any atmospheric features.

The average temp is -353 degrees Fahrenheit. (space.com) Does Neptune have an atmosphere? If so what is it mostly composed of? Neptune atmosphere by volume is Molecular hydrogen 80%, Helium 19%, Methane 1.5 %, hydrogen deuteride 192 parts per million 7 ethane 1.5 part per million. (space.com) How many moons does Neptune have and facts about them? Neptune has 14 moons the biggest being Triton which slightly smaller than Earths moon. Triton orbits Neptune backward it is the largest moon to do so. On July 15 the 14th moon was discovered and is temperately called S/2004 N 1. Triton is one of the four moons in the solar system to have an atmosphere. Neptune has seven inner moons Naiad, Despina, Galatea, Larissa, S/2004 N 1 and Proteus. (Space.com) Some interesting facts bout Neptune? Third largest planet dealing with mass. It is also the fourth largest planet dealing with diameter. Has the second largest gravity of any planet. Spins quickly on its axis. Neptune has the strongest winds in the solar system. Its surface gravity is almost like Earths. It’s also the coldest planet in the solar system. It’s a gas like planet. Neptune has five many rings that are Haller, Le Verrier, Lassell, Arago, and

Uranus does not have a rocky core. Uranus atmosphere is 83% hydrogen,15% helium,2% methane. Like the other gas planets, Uranus has bands of clouds that blow around rapidly. Uranus has a type of blueish color from all of the gases that are on the planet. It gets to about 9,000 Fahrenheit at the core of the planet. Uranus is the seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System.

There can never be life on Uranus it’s too cold and too far away.There is no life on this plant. It is made of 83%hydrogen 15% helium and 2% methane. Uranus is blueish greenish color because of the methane in the atmosphere.

Saturn is a gas giant, made up by mostly hydrogen and some helium, both very light elements which make Saturn the only planet denser than water, which means it could float in a bathtub! (If large enough, of course) Hydrogen and helium are also the same elements that make the sun. Inside Saturn, there is a tiny, dense core made up of rock, ice and other elements made solid by the pressure. This core is surrounded by a layer of

Jupiter has a dense core with a mixture of elements, a surrounding layer of liquid metallic hydrogen with some helium, and an outer layer predominantly of molecular hydrogen

Uranus and Neptune are distinctly bluer than Jupiter and Saturn because of the atmosphere. Uranus and Neptune are blue because the atmosphere contains methane. Methane is a colorless and odorless gas that occurs abundantly in nature. Methane damages our climate when it's released during natural gas production and distribution. Methane absorbs light and the light reflected back is blue.
