Planets in Order of Size

This article presents you with important facts related to the size of the planets in our solar system, and their arrangement with regards to this parameter.
Although quite large by itself, the solar system is just a minute part of the vast universe, and is believed to be billions of years old. It consists of the sun in the center and several other bodies including the planets, their satellites, asteroids, meteoroids etc., all revolving around the Sun.
Arrangement of Planets According to their Size
Mercury
It is the smallest planet in our solar system. The diameter of Mercury is 3031 miles (4,878km), which is 38 percent of the Earth's diameter, and its volume is only 5.4% of the Earth's total volume. It is the closest planet to the Sun.
Mars
Planet Mars has often been a subject of extraterrestrial life, as space researchers believe that water existed on Mars about 3.5 billion years ago. However, it is actually much smaller than our planet with a volume of eight percent of that of the Earth. The diameter of Mars is 4,222 miles (6790 km). Although it is the 4th planet in the solar system, it stands in the second position when placed in the order of increasing size.
Venus
It is a rocky planet characterized by the presence of a thick blanket of yellowish clouds filled with sulfuric acid. It has a diameter of 7,521 miles (12,104 km), and is located at a distance of 0.72 AU from the Sun. The surface of planet Venus is filled with a number of large volcanoes.
Earth
It is one of the most amazing planets of the Solar System. It is the only one where life can sustain. With a diameter of 7,926 miles (12,756 km), it stands in the 4th position of this list. However, it is the largest of the terrestrial planets of the solar system. With major part of the surface being covered with water, it is also known as the blue planet.
Neptune
As Pluto is no more counted as a planet, Neptune is the last planet in our solar system. It is 30,775 miles (49,528 km) in diameter, and is located at a distance of 30.06 AU from the Sun. It has 13 moons and rings around it, and is mostly made up of ice and rock.
Uranus
This celestial body has a diameter of 31,690 miles (51,118 km), and is the third largest planet of the Solar System. It is located at a distance of 19.18 AU from the sun, and has 27 moons and 13 rings around it. One of the interesting facts about this planet is rotates at an axis of 90 degrees, and spins sideways, unlike other planets that spin in a vertical manner.
Saturn
It is one of the most complex and researched planets of the solar system. This is mainly because of its rings and its natural satellites. It is believed to have 52 moons or natural satellites. The diameter of Saturn is 74,898 miles (120,536 km), and it is the 2nd largest planet of the solar system.
Jupiter
It also known as the king of planets, is the largest one of the Solar System. It has a diameter of 88,700 miles (142,800 km), and is located at a distance of 5.20 AU from the Sun. Jupiter also has the largest number of moons revolving around it.
If you compare the size of all the planets with that of the sun, you will observe that they won't even come close to the Sun's massive gigantic proportions.
