Mercury is the closest planet of the solar system. Its mean distance from the sun is 0.387 astronomical units. Being the nearest planet to the sun, Mercury receives a lots of sun heat therefore its temperature is high.

Jupiter is the heaviest planet of the solar system and the weight of Jupiter is 85 earth pounds. Earth weighs 6,000,000,000,000,000,000,000,000 (6E+24) kilograms. It is also the largest planet with biggest diameter of 143,000 km. Because of its large size, Jupiter is the heaviest planet of the solar system.

Venus is called morning star of the solar system. It is closest to the earth and it is often called earth’s twin because of its same size as earth. Mercury is the closest planet to the sun and it is also one of the hottest planet in the solar system.

Jupiter is not only the largest planet of Solar System but it has another distinction attached with it i.e. planet with maximum number of moons. It has minimum 63 moons. Some of them are even bigger than small planets of Solar system. This planet has important place in Roman Mythology and it is fifth farthest planet from Sun. Ganymede is the largest moon of Jupiter and the largest moon of the solar system.

Uranus is the slowest rotating planet of the solar system. The speed of rotation of the Uranus around its axis is 17 hours and 24 minutes. It means that the day and night time of Uranus is lesser than the earth’s time which is around 24 hours.

Mercury is the smallest planet of the solar system. It is also the closest planet to the sun as well. The equatorial diameter of Mercury is 4,880 km which is the least then any other planet in the solar system. Earlier it was Pluto which was known as the smallest planet in the solar system but after its exclusion from the solar system as a planet by the scientist, Mercury is declared as the smallest planet. Although Mercury is not smaller than pluto (Diameter=2274 Km) as its diameter is greater than Pluto. Mercury is smaller than earth (Diameter=12,756 km).

Venus is the hottest planet in our solar system. The surface temperature of Venus is about 480 ^oC. The reason of highest temperature of this planet is that it is wrapped in thick clouds of gas called carbon dioxide which traps sun heat like the windows of greenhouse. Its oceans have been evaporated due to increasing heat of its surface.

Gaseous planets are those planets of solar system which are chiefly made up of gases. Jupiter, Saturn, Venus, Neptune and Uranus are the gaseous planets of solar system. These gaseous planets are made up of different gases like Carbon Dioxide, Hydrogen and Helium etc. Jupiter has a cloudy and dense atmosphere of hydrogen and helium.  Saturn is also made up of hydrogen and helium where as Venus is wrapped in thick clouds of gas called Carbon Dioxide.

Jupiter is the biggest planet of the solar system. The total diameter of Jupiter is 143,000 or 89,375 miles. Jupiter is the fifth closest planet of the solar system and it is the closest planet to Mars and Saturn.

There are a lots of elements in the universe. There are heavy as well as light elements found in the universe depending upon the atomic number of the these elements. Here is the list of top ten 10 “Most Common Elements In The Universe“. Because of the their presense in other particles in large numbers, they are also “Most Abundant Elements In The Universe”. Hydrogen is the most abundant or most common in the universe . (more…)
