How many years does the earth have to live, and how many years does the earth have to live

In 5 billion years, the Sun will turn into a red giant and swallow the Earth, and finally a white dwarf.

How long does the Earth live?

The Earth still has a lifespan of about 5 billion years.

According to current studies of astronomical scientific capabilities, the lifespan of the Earth to this day should be about 45-5 billion years. It took such a long time to form today's Earth, or rather, such a long time to form today's solar system. According to scientific research and development, the sun has passed its birth stage, and the sun's energy consumption has basically exceeded half.

In other words, the life of the sun is basically about 5 billion years old, which shows that the limit life of the earth is less than 5 billion years.

In 5 billion years, the Earth's lifetime will shrink as the Sun's hydrogen fuel burns out, the Sun's core shrinks, becomes denser and hotter, and its outer layers expand.

Morphological characteristics of the Earth

The shape of the Earth is roughly ellipsoidal. The macroslag number effect of the Earth's rotation causes a slight flattening along the Earth's axis that runs through the poles and a slight uplift near the equator. From the Earth's core, the Earth's equatorial radius is 43 kilometers (27 miles) higher than its polar radius.

Thus, the farthest point on the Earth's surface from the Earth's center of mass is not Mount Everest, the highest elevation, but the summit of Mount Chimborazo in Ecuador, located on the equator.

The Earth's reference spheroid has an average diameter of about 12,742 kilometers (7,918 miles), which is about equal to (40,000 kilometers) This integer is not a coincidence, but because the unit of length in the meter was originally defined as one-ten-millionth of the distance between the equator and the North Pole on the meridian passing through Paris, France.

I can't say for sure how many years, but it's also a trillion.

The Earth is a planet with a diameter of nearly 10,000 kilometers, and it is not easy to bring this star to extinction! The mass of the Earth is as high as tons, and the gravitational binding energy that brings these substances together is as high.

This is an extremely large number, there is a popular saying that the nuclear ** on the earth can destroy the earth earth several times, but in fact, this can't hurt the earth in the slightest, at best, it can only wipe out human beings themselves!

Earth is the third planet in the solar system from the inside and outside, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, about 100 million kilometers (1 astronomical unit) from the sun.

The Earth rotates from west to east while revolving around the Sun. At present, it is 100 million years old, and there is a natural satellite - the moon, and the two form a celestial system - the Earth-Moon system. It originated hundreds of millions of years ago from the primordial solar nebula.

The radius of the Earth's equator is kilometers, the polar radius is kilometers, the average radius is about 6371 kilometers, and the equatorial circumference is about 40075 kilometers.

The Earth's surface area is 100 million square kilometers, of which 71% is oceans and 29% is land. The atmosphere is mainly composed of nitrogen and oxygen, as well as small amounts of carbon dioxide and argon.

The Earth has about four or five billion years left to live.

The Earth's lifespan is about 10 billion years, and it is now about halfway over. In other words, in four or five billion years, the earth will die out, because the end of hydrogen fusion in the sun and the beginning of helium fusion, which is the sun turning into a red giant, swallowing Mercury, Venus, and the earth, and only Mars survives among the terrestrial planets.

1. The earth is a planet accumulated from the original solar nebula, and it has been more than 100 million years since then, and the sun will become a red giant star in 100 million years, and the sun after the core burns out, the gravitational loss volume will become larger to swallow the earth, so the earth will be as hot as a furnace at that time, and the descendants of human beings will have to fly to other planets to live.

2. In about 5 billion years, the hydrogen element inside the Taimengyang will be almost completely depleted, and the core of the sun will collapse, causing the temperature to rise, and this process will continue until the sun begins to fuse helium into carbon, because the energy produced by helium combustion is more than that produced by hydrogen combustion, so the outer layer of the sun will expand, and a part of the outer atmosphere will be released into space.

3. If the sun's energy is depleted, then its center will collapse. At that time, the sun will not be able to provide energy to the earth, and the earth will also be "swallowed" by the center of the sun. From the perspective of the impact of the sun's lifespan on the earth's lifespan, the earth's lifespan is about 5 billion years. Never talk.

The lifespan of the Earth is about 9.6 billion years. Through data comparison, scientists have found that for the next 2 billion years, the earth will still be suitable for human life, which is a bit surprising, which is fortunate for humans. There are countless possibilities for 2 billion years, and with the rapid development of science, people may find a second home in space for human beings to move to.

The history of the Earth's generationAccording to scientific records, the birth of the earth was about 4.6 billion years ago, the original earth is different from today, the original earth was formed as a blazing fireball, and there was no life at all. It was during the second evolution of the earth that some primitive ecosystems were formed.

According to the history of the Earth, the inference of the continental drift hypothesis shows that in the second stage of the Earth's development, the Earth continuously released energy outward, forming large-scale water vapor, carbon dioxide and other substances, and finally evolved into the original atmosphere.

There is no one definite number for the lifespan of the earth as it is affected by many complex factors. According to scientists' estimates, the Earth has been around for about 4.5 billion years and is expected to continue to exist for billions of years. However, life on Earth may face some challenges in the millions or billions of years to come, such as climate change, large-scale natural disasters, or possible planetary collisions.

But, in any case, the life span of the Earth is much longer than our current lifespan, so we don't have to worry too much about the life span of the Earth.

The first statement;

5 billion 7.5 billion years later, there is a probability that the Earth will be destroyed by the red giant Sun, but not absolutely. At the time of becoming a red giant, the mass of the Sun is expected to be about 30% less than it is now, and if the influence of tides is not considered, the radius of the Earth's orbit will be about an astronomical unit when the radius of the Sun expands to 1 astronomical unit, and it will not fall directly into the Sun; However, computer simulations conducted in 2008 [1] showed that the Earth's orbit would gradually decay due to tidal effects, making it likely to fall into the Sun.

The incremental effect of gravitational perturbation between planets makes the entire inner solar system chaotic in the long run. The orbits of planets billions of years from now are extremely difficult**. Computer simulations of the evolution of the solar system over the next 5 billion years show that the probability of an Earth collision with Mercury, Venus, or Mars is less than 1 in 1, the probability of an extrasolar star passing through the solar system and dragging the Earth out of the solar system during this time is about 1 in 100,000, and the probability of a pair of binary stars passing by the solar system and capturing the Earth away is about 1 in 3 million.

After the above small probability event, the probability that the Earth will fall into a star before falling into the black hole at the center of the Milky Way increases.

The fusion or passing of the Andromeda Galaxy and the Milky Way galaxy may throw the solar system out of the Milky Way, but basically does not cause any direct damage to Earth.

If the Sun had not destroyed the Earth during these epochs, the Earth could have continued its motion around the White Dwarf Sun and waited for the Solar System to gradually fall towards the black hole at the center of the Milky Way, falling into it about 1e30[2] 1e33 years later, or it could have been destroyed in contact with stellar objects much earlier, including hitting the Black Dwarf[3] Sun.

It is expected that the Earth may be thrown out of the solar system by the violent relaxation effect on the 1e19 scale, otherwise the Earth will collide with the black dwarf Sun on the 1e20 scale.

If human civilization, or civilization that emerged in the solar system later than we do, can exist to the point where the aforementioned fate of the Earth needs to be considered, it will have the power to resist all of the above, and therefore the "lifespan" of the Earth may also be extended indefinitely, beyond the possible decay of protons, the tunneling of all the constituent particles, the era of radiation, or the Great Tear.

The second way of saying;

The earth has existed for 4.6 billion years, and the life span of the earth is currently estimated by human beings. Under normal circumstances, planets and moons have no lifespan and can continue to operate without interference from external conditions, while stars have a lifespan, so the lifespan of the sun directly determines the survival of the earth and the moon. The age of the sun is about 5 billion years, and it can continue to burn for about 5 billion years.

According to scientists' estimates, the Earth is 4.6 billion years old, and it is estimated that it will have another 3 billion years of life, and the Earth will be swallowed up by the extremely expanding sun.
