You all probably know all the names of the planet in the solar system because you have studied in school before. Further, there are many things to know about our planets. You might not remember anything other than the names of the planets, such as the size of the planets.

At night, when you look up at the sky, you probably see a few small planets there. But is it really that small? No, all planets have different sizes. Some planets are smaller than Earth and some planets are very larger in size.

Today here in this article, you will know the size of the planets in order from smallest to largest in Diameter. You will also get some additional information about that planets. Such as:- when those planets formed, days to complete revolution around the sun, smallest and largest planets in solar system, and planets size comparison in order.

The Planets in Order from Smallest to Largest

Well, there are 8 planets in our solar system, but Pluto was also a part of our solar system until the International Astronomical Union (IAU) downgraded Pluto’s status to a dwarf planet in 2006. Here you will also know about the dwarf planet “Pluto” also.

Note:- The sizes of planets in diameter given below are taken from the official website of NASA.

The Size of all planets in order are:-

• Mercury
• Mars
• Venus
• Earth
• Neptune
• Uranus
• Saturn
• Jupiter

Please Pay attention, if you have a curiosity about astrophysics, cosmos then you must have this book “Cosmos” by Carl Sagan. It is the most recommended and best seller book of all time.

This book will tell you the story of 15 billion years of cosmic evolution. Transforming matter and life into consciousness, how science and civilization grew up together and the forces and individuals who helped shape modern science.

Mercury

The smallest and closest to the sun of our solar system. This planet was formed about 4.5 billion years ago. It takes 88 Earth days to orbit the Sun. Mercury Planet is slightly larger than Earth’s Moon and 1/3 (0.38%) the width of Earth.

Mars

Mars is the fourth planet from the Sun and the second smallest planet in our solar system. This planet is also known as the Red Planet of our solar system. Mars planet was formed about 4.5 billion years ago. It takes 687 Earth days to orbit the sun. It has two moons:- 1). Phobos 2). Deimos

According to scientists, Mars is the only planet where strong signs of life were present long ago when it was warmer and covered with water.

Venus

Venus is the second planet from the sun and the third smallest planet in our solar system. This planet is also known as Earth’s Sister. It is the hottest planet (average temperature is 800^oF or 430^oC) in our solar system.

Venus Planet formed about 4.6 billion years ago. It takes 225 Earth days to orbit the sun. The Size of Venus is similar to the size of Earth (0.95 times earth size).

Earth

Well, we are all familiar with this planet, because it is the only planet where life exists. In other words, It is our home planet.

Earth is the fourth smallest and fifth largest planet in our solar system. This planet was formed around 4.54 billion years ago. It takes 365 days to orbit the sun. Earth is slightly similar to the planet Venus in size. The size of Earth is around 1/109 times as compared to the Sun.

Neptune

Neptune is the Ice Giant and the most distant planet in our solar system. It is the fifth smallest and the fourth largest planet of our solar system. Neptune formed about 4.5 billion years ago. It takes 165 earth years (60, 190 Earth days) to orbit the sun. Neptune planet is about 4times the size of Earth.

Uranus

Uranus is also the ice giant the seventh planet from the Sun. It is the sixth smallest and third largest planet in the solar system. This planet formed about 4.5 billion years ago. It takes 84 Earth years (30, 687 Earth days) to orbit the Sun. Uranus is almost 4times the size of Earth.

Fact:- A Fact Between Neptune and Uranus You Should Know, Neptune is smaller than Uranus but it is heavier in mass. This is just because of the high density of Neptune. In other words, Uranus is larger than Neptune but it is lower in mas. This is just because of the low density of Uranus.

Saturn

Saturn is the sixth planet from the Sun and the second largest planet in our solar system. This planet formed 4.5 billion years ago. It takes about 29 Earth years (10, 756 Earth days) to orbit the Sun. Saturn planet is about 9times the size of Earth.

Saturn is a gas giant planet and is also known as “The Ringed Planet”. It’s just because it has a very beautiful ring made of ice and rocks. Further, I say the planet Saturn is the most beautiful planet in our solar system.

Jupiter

Planet Jupiter is the fifth planet from the sun and the largest planet in our solar system. This planet is also a gas giant planet and formed around 4.5 billion years ago. It takes about 12 Earth years (4, 333) to orbit the sun. This largest planet is approximately 11 times the size of Earth.

One fact you should know, although Jupiter planet is the largest planet but it has the shortest day in our solar system. In one day, Jupiter takes only about 10 hours.

Pluto

Pluto is a dwarf planet in our solar system. Well, it used to be a planet, but in the year 2006, the IAU (International Astronomical Union) classified it as a dwarf planet.

Pluto is the largest dwarf planet in the Solar System, but it is smaller than the Earth’s moon. This planet formed about 4,5 billion years ago. It takes around 248 Earth years (90, 500 days) to orbit the sun. This planet is around 1/6th the size of the Earth.

Size of Sun and Moon

Sun

Sun is a yellow dwarf star and the largest object of our solar system. This star formed about more than 4.5 billion years ago. The sun is about 109times the size (in Diameter) of Earth.

But by volume, the Sun is about 1.3 million times bigger than Earth. In other words, About 1.3 million earth could fit inside the sun.

Moon

The Moon is the only natural satellite of the Earth. This moon is the fifth largest moon in our solar system. It takes around 27 days to make one revolution around the Earth. The size of the Moon is about 1/3rd the size of the Earth.

Conclusion

Now you must have known that what are the sizes of all the planets. You have known all the planets in order from smallest to largest. Well, the smallest of these planets is Mercury and the largest planet is Jupiter.
