Gases are a major component of the atmospheres of all the planets of our solar system. Different planets have different composition of gases among them but some of planets are completely made up of gases or gaseous particles. There are five planets which are regarded as the most gaseous planets in the solar system. These planets include Jupiter, Saturn, Venus, Neptune and Uranus.

Jupiter is the biggest planet of solar system and it has two elements, which are major in its composition. These elements include the particles of hydrogen and helium gases . Saturn is which is second biggest planet and also has a similar atmospheric and structural composition as of Jupiter. Major elements are hydrogen and helium gases and other minor elements include ammonia, water, and other sulphides of hydrogen. The third gaseous planet in the solar system is Venus which is the second closest planet to the sun. It is also similar to the earth in all aspects including shape, size and structure. This planet has a very hot atmosphere due to green house effect and has 90 times more atmospheric pressure than earth. It has been surrounded by carbon dioxide, dense fumes of sulphuric acid and traces of water. Neptune is eighth farthest planet from sun and the fourth planet which is chiefly made of gaseous particles. Its atmosphere has various elements, which remain unidentified untill now, while other identified ones are helium, hydrogen and methane. Blue color spots are seen in its upper atmosphere. Uranus is planet, which is a big ball of liquids and gases. It contains hydrogen and helium, thick dense water fumes and ammonia in form of ice mountains.
