gaseous planets

Gas planets:

 The gaseous planets, which are also called Jovian Planets, are Jupiter, Saturn, Uranus, and Neptune, and were named so because of their gaseous composition, consisting mainly of helium and hydrogen gases, in addition to having a small rocky core.  With its large size, it is located in the outer part of the solar system, specifically outside the orbits of Mars and the asteroid belt, knowing that Jupiter and Saturn have a larger size than Uranus and Neptune, and each pair of these planets has a different composition and characteristics, which distinguish it from others.

Characteristics of gaseous planets:

 The surfaces of gaseous planets are amorphous, that is, they do not have a solid surface;  This is due to its gaseous composition that has no specific surface.  Its mass consists mainly of helium and hydrogen gases.  It has a very dense atmosphere;  Which contributes to the survival of gases on these planets, preventing them from spreading to outer space.  All of these planets have large numbers of moons and rings.

 These planets are called Jovian after Jupiter; reason for this name is attributed to its great similarity with Jupiter in terms of size and characteristics.  These planets have a lower density gas composition, while their core is more dense;  This is due to its rocky composition.  These planets receive very little light;  Which makes its temperature very low.  It rotates around itself very quickly, which is estimated at an average rotation of about 10 hours, in contrast, the speed of its rotation around the sun is relatively slow.

 It has a very strong magnetic field and gravity, which allows it to retain all gases on its surface.  All of these planets share similar and close atmosphere and climate patterns.

 What are gaseous planets?

 1- Jupiter:

 Jupiter is characterized by the following: It is one of the largest planets in the solar system, knowing that its diameter is about 11 times the diameter of the Earth.  It consists of hydrogen and helium gases, as these gases surround a rocky and icy core of high density.  50 of its satellites have been discovered so far.  Its atmosphere is made up of hydrogen and helium gases, along with ammonia and methane.  It can be seen from Earth with the naked eye.

2- Planet Uranus:

 The planet Uranus is distinguished by the following: It was discovered in 1781 by the scientist "William Herschel".  Its diameter is approximately 4 times the diameter of the Earth.  It has the advantage of being the only planet in the solar system that has a lateral tilt, which gives it the ability to rotate around itself in the opposite direction to the rotation of the rest of the planets of the other group, except for Venus.  This bumping is tilted on this picture.  Uranus has 27 moons.  Its atmosphere is made of hydrogen, helium, and methane.

 Saturn is characterized by the following: Saturn one of the least dense planets in the solar system.  It has a rocky core made of liquid metallic hydrogen.  The most prominent characteristic of Saturn from other planets is that it has a large number of rings, which were formed as a result of the accumulation of huge numbers of small blocks of rocky and icy materials, and these rings revolve around the planet in fixed orbits.

 Neptune :

 Neptune has a mass of about 17 times the mass of the Earth.  It is characterized by its high wind speed, which is considered the fastest in the planets of the solar system, reaching 2000 kilometers per hour.  Because its atmosphere contains methane, it appears blue when viewed.  It has a number of rings that can be seen from Earth, but they appear dark and faint.

 Thirteen of its satellites have been discovered. The largest of these moons has been named "Triton", knowing that Triton can orbit around Neptune in the opposite direction to the Earth's rotation, unlike all other moons of the solar system.
