Solar System Planets in Order | Full Guide and Facts

Solar system Planets in order

Our home planet is known as Earth. Earth is the only planet in the solar system where life exists, but it’s not the only one in the universe. Our solar system has eight planets around the sun, including Earth.
In order from the sun, the solar system has eight planets, 146 moons, numerous comets, asteroids, space rocks, ice, and a sun as a star, as well as a few dwarf planets like Pluto.

Solar System Planets in order

The solar system contains eight planets, in order from the sun. An easy mnemonic for remembering the order is “My Very Educated Mother Just Served Us Noodles.”

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

Mercury the First Planet in Solar system

Solar system Planets in order

Mercury is the smallest and first planet in order, as well as the smallest of the seven planets in the solar system. This planet is just a little bit bigger than the moon. Mercury circles the sun once every 88 earth days, making it the fastest planet in the solar system, but it rotates on its axis so slowly that one day on Mercury is as long as two months on Earth. And this planet gets very hot during its long days—over 425 degrees Celsius—hot enough to melt some metals. Then, because Mercury has no air to hold heat, the temperature drops to -180 degrees centigrade, which could give you a serious case of frostbite. 

Intresting Facts

  • Some astronauts once thought they had seen another planet even closer to the sun than Mercury they call this planet Vulcan. Scientists now believe that Vulcan does not really exist but no one knows for sure.
  • Diameter – 4880 kilometer 
  • distance from the sun – 57 90000 km 
  • Number of moons – 0

Venus is the Twin Planet of Earth in our Solar System

Solar system Planets in order

Venus is the second planet in order from the sun in our solar system and is the closest neighbor to Earth and the surface of Venus might have been much like that of Earth, but no one could be sure because Venus is always covered with clouds, and the evening star refers to Venus in some instances. Besides the sun and the moon, Venus is the brightest object in the Earth’s sky. Sometimes it is even visible in the daytime.

Intresting Facts

  • In the 1970s, sent several robot space probes to Venus. The probes quickly stopped working at the surface of Venus, and a blast furnace at over 450 degrees. Not only that, the atmosphere on the surface is so dense that moving through it would be like trying to walk through water. The whole planet is in the middle of a rainless thunderstorm that has been going on for millions of years and shows no sign of letting up. Not a good place to take a vacation. 
  • Diameter – 1200 km.
  • distance from the sun – 108200000 kilometers
  • number of moons – zero 

Earth is the Planet of life in our Solar System

Solar system Planets in order

In many ways, the third planet in order from the sun in the solar system is Earth, the strangest one of all. It is the only planet to have an ocean, the only planet to have an oxygen and nitrogen atmosphere, and the only planet known to contain life. The Earth has the combination of light, atmosphere, water, and temperature that are necessary to support life. It is the only planet with sandy beaches, chocolate ice cream cones, and music, and Earth is also the first planet from the sun to have a moon. The moon orbits the Earth once a month. 

Our home planet, Earth, is the only planet that can host life. Even though the solar system contains enormous amounts of water, only the Earth can support liquid surface water. With a surface area of about 71%, the oceans cover more of the planet’s surface than polar ice, lakes, and rivers combined. Land makes up 29% of the planet’s surface of continents and islands. The slow-moving tectonic plates that make up the Earth’s surface interact to form mountain ranges, volcanoes, and earthquakes. The magnetic field created by the Earth’s liquid outer core shapes its magnetosphere and deflects harmful solar winds.

Intresting Facts about Planet Earth

As Earth turns, the gravity of the moon and the sun pulls on Earth’s ocean and in order to causes the water level to rise and fall; this is called the tide.

  • We think of the Earth as the best planet to live on because we are used to it. If a creature from Venus came to Earth, it would not be comfortable on Earth because it would think the Earth was a cold planet, a wet planet with thin poisonous air.
  • Diameter – 12,756 km 
  • Distance from the sun – 1 50, 000, 000 
  • Number of moons – 1 

Mars the Red Planet in the Solar System

Solar system Planets in order

In the 19th century, astronomers looked at Mars through telescopes and thought they saw canals crossing its surface, and some people thought this meant there was life on Mars. We know that the ‘canals’ seen on Mars were an optical illusion. A space probe landed on Mars in 1976 and sent back some nice pictures of the red rocks but found no signs of life.

Intresting Facts

  • Surface conditions on Mars are more like earth than on any of the other planets, but you would still be comfortable in a t-shirt. People might live on Mars in the future, but they would have to wear space suits to go outside. The temperature on Mars drops to as low as -150 degrees centigrade, and the thin air contains only traces of oxygen. 
  • Mars has the tallest known mountain in the solar system. Olympus mons. This volcanic mountain is over 24 km high, three times higher than the highest mountain on earth.
  • Diameter – 6787 km
  • Distance from the sun: 228000 000
  • Number of moons – 2

Jupiter the Gas Giant in the Solar System

Jupiter is the largest planet in the solar system, and it is the fifth planet. This planet is bigger than any other planet; it’s twice as big as all of them, and the gravity there is so strong that if you weighed a hundred pounds on Earth, you would weigh 265 pounds on Jupiter.

Because it is mostly made up of hydrogen and helium, Jupiter is called a gas giant. The atmosphere is about 1000 km thick. The deeper you go into the atmosphere, the denser the gases become until they turn to liquid. Scientists believe this liquid hydrogen and helium might be another 20,000 kilometers deep. If you decided to land your spaceship on Jupiter, you would sing for a long time before you hit solid ground. 


  • Jupiter is also known as the gas giant.
  • Jupiter has some giant storms to go along with its giant size. One super hurricane, which looks like a big red spot, is over 30,000 km across and has been going on for several hundred years.
  • Jupiter has some giant storms to go along with its giant size. One super hurricane, which looks like a big red spot, is over 30,000 across and has been going on for several hundred years.
  • The diameter of 142,200 km
  • Distance from the sun is 778 000,000.
  • number of moons: 16 

Saturn is a planet with rings.

Solar system Planets in order

Saturn is the second largest planet in the solar system and is located as the sixth planet in order from the Sun. This planet is the most beautiful of all. Atmosphere: A vast ring system that is nearly 300,000 km in diameter surrounds its multicolored, striped atmosphere, and when early astronomers first saw these things through their telescopes, they thought they had seen a solid band, but now we know that Saturn’s rings are made up of millions of small, icy rocks.

It is a gas giant with an average radius of roughly nine and a half times Earth’s. It is only one-eighth as dense as the Earth on average. Saturn, however, is over 95 times more massive due to its larger volume. 

Saturn, like Jupiter, is primarily composed of hydrogen and helium, and only 10 1/2 hours make up a day on Saturn. Its dense atmosphere constantly swirls around the planet, giving it a desolate appearance. The wind has a maximum speed of 1500 km/h.

Intresting Facts

  • The age of Saturn is 4.5 billion years.
  • Saturn is one of the lightest planets for its size. If there were a large enough ocean, Saturn would float.
  • There are other ringed planets besides Saturn. Jupiter, Uranus, and Neptune have rings, too, though not as spectacular as Saturn’s.
  • Saturn has more moons than any of the other planets. With at least 20 of those moons, plus the hundreds of rings, you wonder how they keep from crashing into one another.
  • Diameter;119, 300 km
  • Distance from the Sun: 1,427,000,0000
  • number of moons: 20 or more

Uranus the sideways planet in the Solar system

The Greek sky god Uranus, the great-grandfather of Ares, and the grandfather of Zeus, and the father of Cronus, has the fourth-largest planetary mass and the third-largest planetary radius in the solar system. 4.5 billion years old.

Uranus was discovered in 1978, and all the closer planets can be easily seen, but you need a good telescope to find Uranus in the night sky.

We only knew a little about this seventh planet when the space probe Voyager 2 visited Uranus. In 1977, they put Voyager 2 into orbit, and it traveled to Jupiter and Saturn before making its way to Uranus in 1986. Voyager 2 discovered that Uranus has 15 months instead of 5 and that Uranus has a ring system.


  • Each of the other planets spins on an axis at a right angle to the sun, but Uranus has its axis pointing directly at the sun. One end of the universe is always in sunlight, and the other is always dark. On Uranus, the South Pole is the sunniest place on the planet.
  • Diameter 51800 kilometer
  • The distance from the sun to 870 000 000 km
  • Number of moons – 15

Neptune the Blue Planet in the Solar system

Solar system Planets in order

Neptune’s farthest known solar planet is the eighth planet in order from the Sun, and it is the densest giant planet in the Solar System. It is 17 times as massive as the Earth and slightly heavier than Uranus. Additionally, Neptune is 4.5 billion years old.

Neptune is about the same size as Uranus but is twice as far away from the Sun. Trying to see Neptune from the Earth is like seeing a pea from a kilometer away. Even the best telescope can show us little of Neptune.

Like Uranus, Neptune is composed mostly of hydrogen and helium, and it is a cold, stormy planet with temperatures as low as -220 degrees centigrade and wind speeds of up to 1200 km per hour. One storm system, called the Great Dark Spot, is big enough to swallow the Earth.

Intresting Facts

  • After visiting Uranus, the space probe Voyager 2 went to look at Neptune, the 8th planet. Voyager 2 found Neptune to be a lovely blue planet with 8 moons, six more than had been thought. It also discovered a faint ring system.
  • Most Neptune moons move in the same direction as the planet, but Triton, the largest moon, goes the opposite. Triton is 4800 km in diameter, about the same size as the planet Mercury.
  • diameter: 49500
  • Distance from the Sun: 4497 00000
  • number of moons – 8 

Pluto the dwarf Planet in the Solar System

In the Kuiper belt, a ring of bodies beyond Neptune’s orbit, Pluto is a dwarf planet. It was the first thing in the Kuiper Belt to be found in 1930. It was always a strange object, but it was officially recognized as the ninth planet from the Sun. 

Pluto’s orbit takes it further away from the Sun than any other known planet, and it is so far away that the Sun would look like a bright star if you were standing on Pluto. The temperature on Pluto is about -240 degrees Celsius, cold enough to freeze air.

Intresting Facts

  • Pluto also has an age of 4.6 billion years.
  • Because of Pluto’s small size and peculiar orbit, some astronomers believe it is a moon that has escaped the gravity of Neptune. 
  • In 1978, James W. Christy discovered that Pluto has more of its own. The moon is named Charon and is almost half as big as Pluto. Pluto and Charon orbit each other like the two ends of a spinning dumbbell.
  • Diameter of 3200km
  • Distance from the Sun: 5900000000
  • Number of moons; 1

Intresting Facts about Stars in the solar system

The Sun is the center of our solar system. It is a fiery, glowing ball of hydrogen and helium. Gravity is the invisible force that holds the solar system together. The sun is also very powerful, and the sun holds all the planets in their orbits by the force of gravity, preventing them from flying off into deep space. In our solar system, there are lots of stars, but they are so far away that we can only see them as points of light. In the solar system, some stars might also have planets, but not sure.

Recent Research about Dwarf Planets in the Solar System

A NASA satellite has discovered the planet LP 890-9b, which is only 2.7 days away from the Sun and is about 30% larger than Earth. This fictitious Neptune-sized planet travels beyond Pluto on an elongated path around our Sun and researchers have given the object the name “Planet Nine,” which could be about 10 times as massive as Earth and orbit the Sun on average about 20 times farther away than Neptune.

Two planetary scientists discovered one of the closest rocky planets outside the solar system and claimed that a ghost planet lurks deep in the solar system, far beyond the orbit of Pluto.

Proxima Centauri, one of our neighbors, has a planet orbiting it similar to Earth. This planet is currently our best option for supporting human life, and NASA’s Spitzer Space Telescope took temperature readings of the planets.

There are currently 55 planets known to science that resemble Earth. 55 seems insignificant in comparison to the more than 4,000 known planets. There are too many prerequisites for Earth-like planets to exist for them to be as prevalent as other types of planets. 


Do you know some interesting facts about the solar system planets in order? And does research show that there are eight planets in our solar system in this order, or are there eight? Could there be other planets far beyond the orbits of Neptune and Pluto? One day, someone with a very powerful telescope might be looking in exactly the right place at exactly the right time and see a tiny spot of light. Maybe it will be you.

Some important FAQs about the Solar System Planets in order

How do I learn the order of the planets?

My Very Educated Mother Just Served Us Noodles

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

Why is Pluto not a planet anymore?

Pluto does not have a neighborhood or other objects, making it a “dwarf planet.” This indicates that Pluto still has a high number of asteroids and other space objects as opposed to other planets, which are gradually absorbed over time.

Who named the planets?

Most of the eight planets in our solar system have names that come from Roman mythology. The five planets that were visible to the naked eye in the night sky were given the titles of gods and goddesses by the Romans.

What is the real name of Earth?

It is a misconception that TERRA is the scientific name of the planet EARTH.

How old is our Earth?

The Earth is 4.543 billion years old.
