After the planets originate from the sun, they gradually move to a stable state and begin to orbit the sun. The four planets that are closest to the Sun are transformed into solid terrestrial planets. And the four distant planets remain as "Jovian monsters"! Monsters are so called because they are much larger in size than terrestrial planets.And Jovian says because their nature is like the planet Jupiter.

Since the discovery of Pluto in 1930,everyone has known that there are 9 planets in the solar system.But after the International Astronomical Union removed it from the list of primary planets in 2006, the number of major planets stood at six.However, in 2017, there are some clues about the existence of another ninth planet.

Mercury,Venus,Earth, Mars,Jupiter,Saturn,Uranus and Neptune can be found by writing the names of the planets in the order closest to the Sun in our solar system.


Mercury: The first planet in the solar system of the closest planet to the Sun is Mercury.Its size is slightly larger than Earth's satellite Moon. During the day its surface temperature is about 450 degrees Celsius.It was discovered and named by ancient astronomers because it can be seen with the naked eye. It is named after the Roman god Mercury, who was the god of commerce, rhetoric, communication, and so on.Bengali Mercury is named after the Hindu god Mercury who is called the son of the moon.The diameter of this planet is 4.6 kilometers.It revolves around the sun once every 7 days as the earth,which means that one year is equal to 7 days of the earth.But it takes 56 days, 15 hours and 30 minutes as a day from Earth!Its gravitational pull is two and a half times less than that of the Earth.


Venus:Venus is located after Mercury.Venus is the hottest planet in the solar system.Its size and nature are somewhat similar to Earth's but its atmosphere is filled with toxic gases. Due to the greenhouse effect, the planet gets so hot from the heat of the sun.Its gravitational pull is almost equal to that of Earth. Interestingly, Venus is the only planet in the solar system that rotates clockwise on its own axis.The ancient Greeks thought of it as two objects, one visible at night and the other during the day.For its brilliance, it is named after the Roman goddess of love and beauty.The name Bengali Venus originates from Hindu mythology.Since Venus can be seen with the naked eye, it has been discovered in ancient times.Its diameter is 12,104 km.The great thing is that Venus takes 225 days to become a year,but it takes 243 days to become one day.


Earth: Earth is the third planet in the solar system and our abode.Life has been found on this only planet in the solar system so far! The Earth's atmosphere is clear and the main constituents are 6% nitrogen and 21% oxygen. Due to its material we see the sky blue during the day.This atmosphere protects us from the sun's deadly cosmic rays and radioactive particles.About 75% of the earth's surface is underwater.Its diameter is 12, 60 kilometers. It takes the earth about 365 days for the sun to turn once or for a year. And one day is equal to about 24 hours.The name Earth originates from the ancient language. Which means soil or land.There is only one satellite of the earth, which is called the moon.


Mars: Mars is the fourth planet in the solar system. The planet is cold and dusty.Its dust is reddish in color due to iron oxide.The planet is rocky and often huge dust storms and tornadoes occur here.It snows on Mars and stores water in the form of ice.Scientists thought it was once full of warm and liquid water.The planet is believed to have a life-sustaining environment.It was also discovered in ancient times as a result of being seen with the naked eye. It is named after the Roman war god Mars, whom the Greeks know as Eris.In Bengal, the name Mars comes after the name of the war god Mars who was the son of the earth.A day on Mars takes 24 hours and 36 minutes and a year takes 7 days. The gravitational pull of Mars is less than half that of Earth. Mars has two satellites,Phobos and Demos.They were both sons of Mars, hence the name of the satellite.


Jupiter: Jupiter is the fifth and largest planet in the solar system. That is why it is often called the king of the planets. The Roman god Jupiter, known to the Greeks as Zeus, was the king of all gods. Hence, it is named after him, Jupiter. The name Jupiter in Bengali comes from Hindu mythology, who was a sage.The planet is almost entirely gaseous, most of which consists of hydrogen and helium.Its body has reddish brown spots due to the presence of other gases.So far, the number of satellites is 69! The magnetic field of this planet is very strong.Ancient astronomers discovered it because it was visible to the naked eye.Its diameter is 1,39,622 km.It takes about 11 years and 9 months to be one year as the earth.Its gravitational pull is about two and a half times that of the Earth.


Saturn:Saturn is the sixth and second largest planet in the solar system.This is because of the ring of one of the most famous planets in our solar system! When Galileo Galilei began observing it in the early 1800's, he thought it was part three!Forty years later, Christian Higgins says the planet has rings. The ring material is a mixture of rock and ice. Scientists are not sure how this ring formed. It has numerous satellites (at least 72), named after various Titans. Saturn is the father of Jupiter, whom the Greeks call Cronus.In Bengal, Saturn is a Hindu deity who is the son of Suryadev and his wife Chhayadevi.Its diameter is 1,20,500 kilometers.One day in 10 and a half hours is here and it takes 29 years and 5 months to be one year.Its gravitational pull from the earth is slightly higher.


Uranus:Uranus is the seventh planet in the solar system.The planet is kind of a little weird, because it tilts and revolves around its own axis. Scientists have long speculated that it may have collided with a large planet-sized object, so this is the case! Due to the presence of methane in the atmosphere, bluish green spots can be seen on its body.It has a light ring and so far 27 satellites have been found!The satellite is named after various characters created by Shakespeare. Uranus, by Greek name, was a prehistoric god, believed to be the sky. In 181, William Herschel identified it as a planet.Its diameter is 51,120 km.It takes about 18 hours from one day to 64 years.Its force of gravity is slightly less than that of the earth.


Neptune: Neptune is currently the last or eighth major planet in the solar system. It is known for very strong storms.Its wind speed is sometimes higher than the speed of sound! Neptune is very cold and its center is hard. Neptune is the first planet whose existence is mathematically conceived before its discovery. French astronomer Alexis Bouvard saw the strange rotation of Uranus and thought it might be due to the gravitational ball of something else.Neptune is about 16 times the mass of Earth.Neptune's gravitational force is a little higher than Earth's. Neptune is named after a Roman water god.The Greeks know him as Poseidon. Its diameter is 49,530 km.It takes 19 hours to be one day and 175 years to be one year!


Pluto:Pluto used to be the ninth planet, but it was dropped from the list because it was smaller than Earth's moon.Pluto is the Roman name for Hades, the Greek god of hell.It is currently listed as a dwarf planet. Mathematical observations like Neptune have also led to the existence of another planet,the ninth planet.Although it has not yet been seen through a telescope.

Thanks for reading.
