Is the earth revolving around the sun, or is the sun revolving around the earth?

Is the earth revolving around the sun, or is the sun revolving around the earth? Think about it! Which is bigger? The sun is huge. Think about why day and night happen again. What did you get? That's right! Not only the earth but all the planets revolve around the sun. And our solar system revolves around the sun.

The solar system

The sun is the main captain of the solar system. Various planets, asteroids, satellites and comets revolve around him. The number three planet is our Earth, where you sit and read the text now.

You may be thinking, the world is too big. So many places. But Jupiter is a much larger planet than Earth. Jupiter is so big that it can hold 1,321 Earths! But the sun is bigger than all. The sun is not a planet, it is a star. As you can see the stars in the sky, so the sun is a star. How big is the sun? Scientists have found that it would take 1.3 million planets like Earth to cover the entire sun!

Some information

There are eight planets in the solar system. These are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune in the order of distance from the Sun.

♦ The sun is a star. Like a big hot gas ball. It contains hydrogen and helium gas. The collision of these gases creates heat and light, which gives light and heat to our earth.

The closest planet to the Sun is Mercury. It has no atmosphere. The farthest planet is Neptune. The largest planet in the solar system is Jupiter and the smallest is Mercury.

♦ Only on earth do animals have a suitable environment to live. Nowhere else has any life been found so far.

The earth can rotate in its own way, that is, in its own orbit. At the same time it revolves around the sun. It takes about 24 hours to travel around the world in its own room. And this is what we call one day. It takes 365 days for the sun to revolve once. We call this one year.

The force that allows us to live, walk, and not fall off is the force of gravity. And because of this energy, the earth and other planets are able to revolve around the sun.

There are some small inhabitants in the solar system who revolve around the planet. For example: our familiar moon mama. It revolves around the earth. The moon is the only natural satellite of the earth. Which is the unnatural satellite? The satellites we send into the sky are artificial satellites.

We see the moon because the sun shines on it.

It takes 28 days and 6 hours for the moon to revolve around the earth once.

The earth is about 151.4 million kilometers away from the sun. It takes 6 minutes and 20 seconds for sunlight to reach the earth.

The earth revolves in its own place. For this reason, the side of the earth that is light now, is dark again. That is why night and day.

The main materials of the earth are soil, stone: all these. There is nothing solid on Jupiter. Totally gas. Venus is very hot. Its temperature is 460 degrees Celsius. The coldest is Uranus. The temperature of this planet is about minus 220 degrees Celsius.

Mars is also called red planet because it looks red. The rocks of this planet look red. It is the closest planet to Earth.

Saturn is the second largest planet. It is surrounded by rock ice and dust belts. This planet is also made of gas.

The only satellite of our earth is the moon. But Jupiter has 69 satellites. Saturn has 72.

The English name of the planet

Mercury = Mercury, Venus = Venus, Earth = Earth, Mars = Mars, Jupiter = Jupiter, Saturn = Saturn. Uranus and Neptune do not have Bengali names.

Creative Q&A

Nuha and Ninad, two brothers and sisters, climbed on the roof at night. They climbed to the roof and saw a beautiful moon in the sky like a round dish. Noah said, "Brother, from now on we will come to the roof every day to see the moon." Ninad, after two weeks this moon will not be seen again. Noah cried out, Brother! See what a beautiful fireball! Lots of fireballs!

A) When is Haley's comet supposed to be seen again?

Answer: In 2072.

B) When do we see meteors in the sky?

Answer: Many small objects and asteroids revolve around the sun. Among these, small objects are called meteors. They can be made of rock, gas, ice and dust. On contact with heat they turn into gas. They burn when they enter the Earth's atmosphere. When burnt, they turn to ashes and spread in the sky. Then it looks like a ball of fire to see from the earth. Thus when many meteors fall together, it is called meteor shower.

C) What are artificial and natural satellites?

Answer: There are eight planets revolving around the sun in the solar system. Again, how many small satellites are orbiting these planets. These are much smaller in size than the planets. They cannot generate heat and light on their own. For example, the moon is the only natural satellite of the earth. We see the moon illuminated when the sun shines on it. When the light of the sun falling on the moon is reflected and falls on the earth, we call it Jyochana. Other planets also have satellites. These are natural satellites.

Man-made artificial satellites are also orbiting the earth. At the moment, about 2500 man-made satellites are orbiting the earth. With the help of these radio and telecommunication, internet communication, weather information etc. are collected.

How are the full moon and the new moon? Explain.

Answer: It takes 28 days and 6 hours for the moon to travel around the whole earth. When there is a full moon in the sky like a dish, it is called full moon. Immediately after this, the moon started getting smaller again. It can't be seen from being small. That condition is called new moon. The night after the new moon, a thin one-sided moon rose in the western sky. Every night it tends to get bigger. Two weeks later, the round moon rose again. Thus after 29 or 30 days there is new moon and full moon.
