Planets in Order from the Sun

Planets in Order from the Sun

Can you name the planets in order from the Sun? If not, then all you need to do is go through the following article and learn all about the planets of the Solar System.
We inhabit the planet Earth, the only planet in the solar system that is known to be able to sustain life. It's not just the Sun and the Earth that make up our solar system. There are many more planets and their moons that make up this unique solar system. It is assumed by astronomers that the solar system is over 4 billion years old. There are 8 planets in order from the Sun that make up the solar system. Let us have a look at these planets and learn more about our solar system in short from the following paragraphs.

Planets in the Solar System in Order from the Sun

The International Astronomical Union (IAU) states that there are 8 planets in order from the Sun. There are 5 dwarf planets in the solar system. Pluto was once considered one of the planets from the Sun, but is now considered to be a dwarf planet. Thus, from a total of 9 planets in the solar system, there are now only 8 planets. The planets are divided into three different categories based on their composition. Let us have a look at the planets in order from the Sun (outwards) according to the categories they are placed in. The third category not covered below consists of the dwarf planets Ceres, Haumea, Makemake and Eris.

The Terrestrial Planets
The four inner most planets in the solar system in order from the Sun are called terrestrial planet. They are called so as they have a rocky, compact surface. Let us have a look at the different planets below:

mercury
Mercury: ☿
Mercury is the hottest, driest planet in the solar system. It is also the first planet from the Sun as well as the smallest planet among all. Mercury orbits the Sun in about 87.969 Earth days. The planet is named after the Roman messenger God, Mercury.


venus
Venus: ♀
The second planet in order from the Sun is Venus. It is called Earth's 'sister planet' as it is very similar to our planet in terms of gravity, size and composition. It is covered with a cloud of poisonous gases like sulfuric acid. The atmosphere of Venus is the densest of all planets and consist of carbon dioxide. It takes about 224.7 Earth days to orbit the Sun. It is named after the Roman goddess of love and beauty, Venus.


earth
Earth: ⊕
The fifth largest planet in the solar system is the planet Earth. It is the only planet that is known to support life. Earth orbits the Sun once after it rotates 366.26 times on its own axis. It is also called the 'Blue Planet' as it appears blue from space. The only natural satellite of Earth is the Moon.


Mars
Mars: ♂
The fourth planet in order from the Sun is Mars. It is also called the 'Red Planet' as it has a reddish appearance due to iron oxide present on its surface. It has a thin atmosphere and has two moons, Phobos and Deimos. This planet is named after the Roman god of war, Mars.


The Jovian Planets
The Jovian planets are also called gas giants. These planets are mainly composed of gaseous matter and are more in mass than the terrestrial planets. These planets have a very small solid core. Let us have a look at these gaseous giants.

jupiter
Jupiter: ♃
The largest planet of the solar system is the fifth planet in the solar system in order from the Sun, Jupiter. It is considered to be a gas giant, but about one thousandth smaller than the Sun. Planet Jupiter has 63 moons, of which four large moons were discovered by Galileo Galilei in 1610. Thus, these moons are called Galilean moons. This planet is named after the Roman god Jupiter.


saturn
Saturn: ♄
The sixth planet is Saturn that is also the second largest planet of the solar system. This gas giant has a radius that is about 9 times larger than the Earth. Saturn has nine rings surrounding it. These rings are made up of ice particles, rocky debris and dust. There are 62 moons that are known to orbit Saturn, of which 53 are named. Within the rings, there are hundreds of 'moonlets'. The planet is named after the Roman god Saturn.


Uranus
Uranus: ♅
The third largest planet of the solar system is Uranus. This planet is fourth largest when it comes to planetary mass. This planet was the first planet to be discovered with the help of the telescope. Uranus is the coldest planet of all with a minimum temperature of about -224 °C. It Is named after a Greek god of the sky, Uranus.


Neptune
Neptune: ♆
The farthest planet in order from the Sun is the eighth planet, Neptune. It was discovered way back in September 23, 1846. It is also one of the coldest planets (-218 °C) as it is very far away from the Sun. This planet is about 17 times the mass of the Earth. It is named after the Roman god of sea, Neptune.
