Can the Earth be older than the Sun? The sun and the earth who are older

In the solar system, the Sun is the most massive central celestial body. The Sun accounts for the total mass of the solar system, so there is a strong enough gravitational pull that the rest of the solar system orbit it. The sun is the only celestial body in the solar system that can emit light on its own, it is the main source of light and heat in the solar system, it illuminates the entire solar system, and also heats the entire solar system.

And the Earth is nothing more than a relatively small planet that revolves around the sun. The age of the earth has been determined by radioactive methods to be billions of years old. So how old is the Sun?

Scientists at the time estimated that the sun was 22 million years old. It's strange that the Earth is more than 100 times older than the age of the Sun! How is this possible?

No way! Astronomers have come up with a different opinion. They said:

Although we cannot take a piece of matter from the sun to directly study its age, there is nothing wrong with one thing, that is, the sun is constantly emitting a lot of light and heat, and how much energy it emits per minute is measured; At the same time, we can accurately calculate the volume and mass of the sun. If the age of the sun is billions of years, like that of the earth, what kind of fuel does it burn? Why does it last so long without extinguishing?

In the 18th century, it was calculated that if the sun were a large lump of coal, it would only burn for 5,000 years if it continuously emitted so much light and heat. This age is obviously too young. Later, the German scientist Helmholtz believed that the sun shines and heats up because it is constantly contracting, converting potential energy into heat energy.

He calculated that the age of the sun was 22 million years, and that it could shine for another 10 million years. His conclusion has been used for half a century, and in order to overturn it, it is necessary to first burn what the sun burns.

It should be younger than the age of the Sun.

Satisfactory answer can't be in the 2008-11-26 The age of the sun is old, give you some scientific knowledge: the age of the sun is about 4.6 billion years, and it can continue to burn about 5 billion years The sun is the closest star to the earth, its size and brightness are medium, and it should be classified as a G1 dwarf star according to its radius and temperature. With a magnetic field and rotation, it is the largest celestial body and contains nearly 98% of the mass of the solar system.

It would take one hundred and nine Earths to fill the Sun's cross-sectional rift, and its interior could hold more than 1.3 million Earths. The visible bright surface is called the photosphere, and above the photosphere is a 5,000-kilometer-thick inner atmosphere called the chromosphere, and above the chromosopher is an extremely thin hot corona that can extend to the Earth and beyond. The activity of the sun is at its core.

The core temperature of the Sun is as high as 15 million degrees Celsius, and the pressure is more than 34 billion times that of the Earth. Nuclear fusion is happening here. Fusion causes four protons or hydrogen atoms to produce an alpha particle or helium nucleus.

The mass of the alpha particle is smaller than that of four protons, and the remaining mass is converted into energy and released to the surface of the sun, where it emits light and heat through the convection process. It takes millions of years for the energy of the sun's core to reach its surface. Every second, 700 million tons of hydrogen are converted into helium.

In the process, about five million tons of net energy are released, thus enabling the sun to shine. The age of the Sun is about 4.6 billion years, and it can continue to burn for about 5 billion years. In the final stages of its existence, the helium in the Sun will be transformed into a heavy element, and the Sun's volume will begin to expand until it engulfs the Earth.

After a 100 million year red giant phase, the Sun will suddenly collapse into a white dwarf - the final stage of all star existence. After a few more trillions of years, it will finally cool down completely. Testimonials from the major third chord:

The sun is bigger than the earth.

The Sun is much larger than the Earth. The diameter of the Sun is about 1,391,000 kilometers, while the diameter of the Earth is about 12,742 kilometers. So the sun is about 109 times larger than the earth.

The earth bulb and the sun are two very important celestial bodies in the universe. The Sun is the central star of our solar system, and the Earth is one of our planetary properties. The Sun is a star that is made up of elements such as hydrogen and helium that produce energy through nuclear fusion reactions and constantly emit light and heat.

Earth, on the other hand, is a solid planet made up of elements such as rocks and metals, which orbit the Sun and has its own rotational motion.

Most of the Earth's surface is covered by water, with unique ecosystems and many species of organisms living in it. The interactions between the Sun and the Earth, such as gravity and radiation, have a significant impact on the Earth's climate and weather.

The relationship between the earth and the sun

The Sun is the center of our solar system, and the Earth is one of its planets. The sun radiates a lot of heat and light, which warms the earth and supports life. It provides the energy that the Earth needs, warms our planet, and supports the existence and reproduction of life.

The gravitational pull of the sun also maintains the stability of the solar system.

The gravitational force between the Sun and the Earth also keeps the Earth stable in its orbit, and the Earth revolves around the Sun, and this orbital motion forms the familiar seasons and day and night variations, affecting our Earth's environment and weather. It also has an impact on phenomena such as the state of the earth and ocean tides. In general, the relationship between the sun and the earth is very close, and together they form a stable ecosystem that plays an irreplaceable and important role in the universe.

The interaction between the Earth and the Sun affects many aspects of our climate, weather and seasons, as well as the survival and development of human beings. Therefore, the existence of the earth and the sun has a profound significance, and they make our universe richer and more colorful.

The Sun is larger than the Earth. The volume ratio of the sun is larger than that of the earth, and the earth is larger than the moon. The sun is a silver star, the largest celestial body in the solar system, the earth is a planet, the only living celestial body in the solar system, compared to the sun is like a grain of sesame, the earth revolves around the sun, and one rotation is a year in the solar calendar.

The moon is a satellite, revolves around the earth, and its volume is naturally smaller than that of the earth, so the sun is larger than the earth and larger than the moon.

The Sun is the central body of the solar system and occupies the overall mass of the solar system. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, and the Sun revolves around the center of the Milky Way.

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 away from the Sun. The Earth rotates from west to east while revolving around the Sun. At present, there is a natural satellite that is 100 million years old, and the moon is 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 volume of the Sun is 1.3 million times that of the Earth, the mass is 330,000 times that of the Earth, and the average density is 3 centimetersThe X0d Sun weighs 270 times the weight of the Moon, and the Sun is like an elephant to an ant compared to the Moon. The distance between the Sun and the Earth is 100 million kilometers, which is 400 times the distance from the Moon to the Earth.

The Sun is a red-hot ball of gas, rising from the surface to the center, with a central area of about 16 million degrees Celsius and 300 billion atmospheres. In the center of high temperature and high pressure to form a huge nuclear reaction area, its composition is hydrogen and helium, when hydrogen is converted into helium, it can release a great amount of energy, this is the nuclear fusion reaction Jane Pi Debate. The energy released in the nuclear fusion reaction is trapped and emitted to the surroundings in the form of electromagnetic waves, which is often referred to as solar radiation.

Five billion years ago, since the day the sun was formed, it has been releasing enormous amounts of energy without interruption, and it is estimated that this state will continue for another 5 billion years. The surface of the sun visible to the naked eye is the "photosphere", the periphery of the "photosphere" is the "chromosphere", and the outermost layer is the "corona", which make up the atmosphere of the sun. The Sun also has a rotational and orbital motion, and the rotation period is about 25 days in the solar equatorial zone and about 35 days in the polar region; The orbital period (the period that orbits the galactic core) is about 100 million years (assuming that the orbital eccentricity is zero).

The earth is larger than the sun, and the sun is bigger.

The volume of the Sun is 1.3 million times that of the Earth; 330,000 times more massive than Earth; It weighs 20 times the weight of the Earth. The Earth is 100 million kilometers away from the Sun, so the Sun is smaller than the Earth when viewed from the ground.

Introduction to the Sun: The Sun is the central celestial body of the solar system and occupies the overall mass of the solar system. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way.

The Sun is a star located at the center of the solar system, and it is almost an ideal sphere intertwined with hot plasma and magnetic fields. The diameter of the Sun is about 1,392,000 (kilometers, equivalent to 109 times the diameter of the Earth; It is about 1.3 million times the size of the Earth; Its mass is about 2 10 kilograms (330,000 times that of the Earth). In terms of chemical composition, about three-quarters of the mass of the Sun is hydrogen, and the rest is almost helium, including oxygen sails, carbon, neon, iron and other heavy elements with less than 2% mass, and nuclear fusion is used to release light and heat into space.
