NEPTUNE

 Neptune is the eighth planet in the solar system. It is the only planet in the solar system that is not visible to the naked eye. It is the only planet in the solar system that was discovered by mathematical calculations.

It is the last planet in the solar system. It is another gas giant.

It is also a blue planet, the blue color is due to the methane that absorbs sun rays that anyway closer to red pigment. So, the only blue color is reflected and the planet appears blue.

This planet completes its revolution in 165 years, and its rotation period is only 16 hours.

This is the only planet that has completed a single revolution in 2011, since its discovery in 1846.

Solar rays take 4 hours to reach Neptune.

This planet has a 28-degree axial tilt. So, this plant also has four seasons similar to Earth and Mars. But every season lasts for 40 years.

This gas giant has clouds of icy material, methane, hydrogen, and helium.

It has a hot soup of water, methane, and other gases.

It has a small solid core. Its core is as large as the size of Earth.

Pluto the dwarf planet, was closer to the Sun than Neptune from 1979 to 1999, this is due to the elliptical path of the revolution pluto. 

Neptune has five rings similar to Saturn and Uranus. These rings are made of gases and dust.  

Neptune has 14 moons.

The pressure, temperature, and surface conditions are nonconductive for life to exist on this planet.

URANUS, GOD OF SKY

 Uranus is the seventh planet of the solar system. It is named after Uranus; the Greek God of the sky. This is the first planet observed by the telescope in 1781.

 It is the third-largest planet in the solar system only after Jupiter and Saturn.

 This planet also has multiple moons. It has faint rings.

 This icy giant has blue-green color. 

color makes it an attractive Planet in the solar system.

 This planet is four-time as wide as Earth. 

This planet has a large ocean of methane and ammonia.

URANUS: THE ROLLING PLANET

 It is tilted 97.77 degrees on its axis due to this tilt this planet rolls instead of rotating as the other planets do. This is the only planet that has such a movement. This planet has the largest tilt on its axis and due to this tilt, the North Pole and the South Pole observe winter and summer alternatively for a span of 21 years.

 This planet rotates sideways. It completes its rotation in 17 hours however; it completes its revolution around Sun in 84 years.

 It has a 97.77º axial tilt. This is the greatest tilt among the planets. This tilt is believed due to the planet’s collision with another planet or moon similar to the size of Earth.

 It rotates east to west similar to Venus. The only two planets of the solar system that rotates East to West are Venus and Uranus.

SURFACE OF URANUS

 This planet does not have any solid surface. Its surface is fluid due to high pressure. It is a cold icy giant that has a blue-green color. This blue-green color is due to access of Methane in its atmosphere. It has hydrogen in diatomic form and Helium in atomic form.

The atmosphere is gaseous that transits to liquid layers. Its mantle is a hot ocean of water and ammonia. Its core is made of rocks. Its core is hot reaching 4982ºC.

 This called icy giant is inhabitable as it doesn't have a solid surface. Its outer surface is fluid and its inner core may be made of rocks. It has poisonous gases in its atmospheres such as Methane and ammonia. Its surface observes high pressure that is enough to crush the spacecraft.

 Methane in the atmosphere of Uranus absorbs red, orange, and yellow colors, it reflects the blue-green color and this gas gives it the particular blue (cyan) color to the planet. 

RAIN OF DIAMONDS ON URANUS

The atmosphere of Uranus has hydrogen, carbon, and methane. These molecules act as seeds for diamond formation. Diamonds are formed under the surface of Uranus at the depth of 8000 km where extreme heat and atmospheric pressure burn methane and convert carbon into diamonds. These diamonds with gas and vapors reach the atmosphere, from where they rain on the surface of Uranus. However, the size of these diamonds is very small, in the range of nanoparticles.

RINGS OF URANUS

 This planet also has a number of rings around it these rings are formed of gases and dust particles. The rings are of a different colors. The inner rings are dark grey in color and the Outer rings are red or pink in color. 

Uranus has thirteen rings. These are named alpha, beta, gamma, zeta, etc. Alpha and beta are the outermost rings. These are light in color.

MOONS OF URANUS

 Uranus is named after the Greek God of the sky. Uranium the radioactive element is named after Uranus. It has 29 moons. Its moon has been named after the characters of Shakespeare and Alexander Pope. Its inner moons are made of half-ice and half rocks.

 Water is present in form of ice. Liquid water doesn't exist on this planet. Due to its low temperature, it has gases in a liquid state and water is in a frozen state. It is the coldest planet in the solar system. Its average surface temperature is -224ºC.

SATURN, THE JEWEL OF THE SOLAR SYSTEM

 Saturn is the second-largest planet in the solar system.  The planet has a gold color and a beautiful ring around it. It has golden clouds of ammonia crystals. This planet with these features appears as the jewel of the solar system.

  Saturn: the lightest planet in the solar system

Saturn is another gas giant after Jupiter. Saturn is the second-largest planet in the solar system. 9 piles of earth can fix into Saturn's equator. It is the lightest planet. Its density is lower than water. It is the lightest planet in the solar system. 

 Saturn, the gas giant has a density even less than water, so this planet will float on water. The only planet that will float on water. 

This gaseous giant has only a solid core, the rest of it is composed of gas only. These gases mainly are hydrogen and helium. 

A large number of satellites

The gas giant is a solar system in itself, that is this planet has a large number of satellites. That may be even more than Jupiter. It has 50 confirmed moon. Titan the largest moon of Saturn is as big as Canada. It has a cloud system and atmosphere. It has oceans under its atmosphere. But it has a high concentration of methane and no oxygen

 Enceladus is the brightest satellite of Saturn. it reflects 100% of the light it receives. The temperature at this moon is -201ºC and its  surface is smooth due to the icy surface

Saturn revolves slowly around the sun, it takes 29 years for Saturn to complete its revolution. However, Saturn rotates very fast it rotates on its axis, and it takes on  10.7 hours to complete its rotation. Saturn is tilted 27. 9 minutes on its axis.

 

The gas giant has large Storms going on it and these terms are about 18000 square km in their diameter. The maximum speed of this storm can be 400 km/h. Saturn cannot support life as it does not have a solid crust. Its atmosphere is very hot gases that are too windy to survive.

 

Beautiful rings of Saturn

 It has beautiful rings around it. These are thin rings that are made of Rocks, dust, and ice flakes. These rings are colorful. These can be only seen through the telescope.

Rings around Saturn are numerous these are separated from each other by gaps these are mainly composed of ice flakes, rocks, and small particles that are equal to their size in the dust. The rings are divided into 7 groups. The rocks' size can be as large as mountains and small as dust particles.

The ring system of Saturn is the most complicated system among the planets. These rings are 4 and half times the earth and 0.66 miles in width. Small moons revolving around Saturn keep the rings in shape. These tiny moons are called shepherd moons.

It has no true surface. Golden clouds and storms. The largest storm on the north pole. It is twice the size of the earth. This storm has a hexagonal shape due to jet streams. Its clouds contain ammonia, H2, and He.
