Solar system: Four billion years ago

Solar system: Four billion years ago

Solar system

Our universe is about 13.8 billion years old. And our solar system is about 4.571 billion years old. That means the age of our solar system, one-third of our universe. From the past to the present, much of our solar system has changed. This change will continue in the future. Over the next 5 billion years, our sun will turn into white dwarf. white dwarf When a star is in position, it eliminates all of its hydrogen fuel. Due to which nuclear fusion is stopped. As a result, the gravity of the stars’ center increases so much that the core collapse becomes white dwarf.

White dwarf

At this time the stars spread billions of kilometers away, clouds of dust and gas. And all these dust and gas clouds are created again, from any other star or planet. The process continues. The white dwarf is so dense that when our sun turns into a white dwarf, the size of our sun will be equal to our earth. But even then, the mass of the stars will be 50 percent of our Sun. Because the sun fuses 620 million tons of hydrogen per second, 609 million tons of helium. And this lost mass of hydrogen atom, converted to heat, made the sun so hot and bright.

After the next 5 billion years, all the sun’s energy will be gone. Which is usually a form of hydrogen. In 5 billion years, our sun will gradually turn into a white dwarf. But how was the start of our solar system? Let’s go back in time, friends. And look back, 4.6 billion years ago. That is how our solar system was in the beginning. So hello friends, you are at fresherfore. Starting today, another informative discussion.

4.6 billion years ago

4.6 billion years ago, the sun, which is surrounded by clouds of dust and gas, will look much less brighter than today. Where the conversion of hydrogen to helium has just begun. That protoplanetary disk from all around. That means all that dust and gas is covered in clouds. Which creates the Planet of our Solar System. Where the temperature is 700 degrees Celsius. Here, due to cosmic pressure and heat, the molecules are united together. And in the next 100 million years, this protoplanetary disk will become Planetary. Let’s go a little further than that, 1.5 billion years after our solar system was created. When the Planet came into existence.

What does our solar system look like now? It has been 1.5 billion years since the sun was built. Now a cloud of dust gas around the sun has transformed into the Planet. And the temperature has dropped a bit. Now we can find out some information about all the other planets in our solar system. But before you know it, there is one thing you need to know. At the time of the creation of the Planet in our solar system, many of the Planet’s existed. Which are not presently. Because maybe all of the planets, along with it, have created a large planet. Otherwise, they are out of our solar system.

Mercury

First let’s start with mercury. That is the closest planet to our sun. The Planet looks pretty flat. This means that during the creation of this planet, due to the lava flowing on this planet, the land of this planet has become quite flat. It is still the only planet in our solar system, which despite its close proximity to the sun, its temperature is much lower than that of Venus.

Venus

Then we will know about the second Planet Venus in our solar system. It is very nice to see Venus today. You can only see the river flowing in the land of Venus. That looks completely different from the current Venus. Looking at the planet now, it looks like we might be looking at another planet in the ocean. The atmosphere of Venus at this time will look very much like the earth. This time you can see some volcanic activity on this planet in your own eyes. Which is still stored on the surface of Venus. But it’s not as horrible as the current Venus. It is believed that 4.5 billion years ago, Venus was the perfect planet for life.

Our house

Now, let’s move from the sun to the third planet. Where is our house. Looking at the world from space, the big continent here is in the eye. But you can’t recognize them now. And this time, the composition of the atmosphere’s atmosphere gas is very different. There is absolutely no oxygen here. But this world, surrounded by huge seas, looks a bit like today. In the next 5 million years, life will begin as a single cell on earth. If we talk about the moon of the earth this time, then there are no craters on the moon. Now the moon is very smooth. Where a few craters are in stock. And all the rest of the craters will come into existence within billions of years.

Mars

Now let’s go to Mars Planet. That’s the fourth planet from our sun. Looking at Mars this time, you will see flowing water and frozen ice. You may be very happy to see that. Because the sun is less bright now. Due to this the temperature of the sun is very low in Mars. The temperature here is quite cold. 4.5 billion years ago, we had three Habitable Planets in our solar system.

Jupiter

Now let’s go to Jupiter. But we don’t know that much about Jupiter and other gas giant Planet. As much as we knew about the rocky planet of our solar system. But little is known about all this gas giant Planet. 4.5 billion years ago, what did all this planet look like? Jupiter is the largest planet in our solar system. Does this Planet look the same as what we currently see? No friends Jupiter’s red cloud patents look quite different and larger. Because its storms were more dire in the past than present. Jupiter’s moon is still with Jupiter. All these moons were created with Jupiter.

Saturn

Now let’s go, Saturn. As we see, there is no ring of Saturn. In the meantime, all of these rings will slowly be caused by the gravity of Saturn’s planet. If I say Saturn’s moon, then the Titan will come first. That is one of Saturn’s 62 moons. But at this time about the past of the Titan, we know nothing about it. As if 4.5 billion years ago, this is what it looked like. Or whether the methane was in liquid form at Titan this time. What was the atmosphere like?

Neptune and Uranus

Let’s go friends, then we go to Neptune and Uranus 4.5 billion years ago. Which is the seven and eight planets from the sun. There are some differences between these two gas giant planets. Neptune’s moon Triton is not near him at present. From this, it is clear that Neptune’s gravity will later transform Triton into its moon. So guys, from one of these discussions I learned a lot of unknown information about our solar system 4.5 billion years ago. If you want to know all this informative exciting information, stay tuned. Be good Thank you.
