How to prove that the sun is bigger than the earth? Comparison of the size of the sun and the earth

1.To know the size of the sun, we can first visually see how big the angle of view of the sun is. It's just how big a disk the sun is.

Then you only need to know the distance from the sun to the earth to calculate the diameter of the sun. For example, the moon appears to be larger than the sun, but the moon is closer, so the moon is much smaller than the sun.

2.To know the distance from the sun to the earth, one also needs to know the orbital period of another planet. For example, the cycle of Mars.

This requires continuous observation by others. The cycle of the earth is known, which is one year. Then according to Kepler's third law, the ratio of the radius of the Earth's revolution to the radius of the revolution of Mars is calculated.

3.Suppose the Sun, Earth, and Mars are in a plane, when the Sun, Earth, and Fire are in a straight line (this opportunity occurs every year). In the plane formed by the Earth's sun, the center of Mars, and the north and south poles, the location where the Sun is on the horizon and the location where Mars is on the horizon can be found visually, and both points are located on the same meridian coil.

When the sun is on the horizon, it means that the sun is perpendicular to the line between the sun and the observation point and the geocentric line, and the latitude of the point is the angle between the sun-earth-fire line and the point-geocentric line. Then you can know the angular relationship. It is easy to draw a diagram to show the relationship between its relative position and angle, which is the knowledge of junior high school.

4.Also know the radius of the Earth. It's easier. Find two points on Earth, measure the arc length of two points, and then look at the same distant star at two points. Then the radius of the Earth is known from the two altitude angles measured. You'll know as soon as you draw a picture.

5.In this way, the distance between the sun and the earth is found.

6.According to the angle of distance between the sun and the earth and the diameter of the sun, the radius of the sun can be obtained from the triangular relationship. Then compare the radius of the sun with the earth to know the relationship between their size.

You can see the shadow of the earth, which is the time of the lunar eclipse.

If you have studied physical optics, you should know that if two spherical objects, one of which is a luminous body, if the size of the two is equal, you make a diagram of the optical path, and the umbra caused by the one that does not emit light is a cylinder; If the one that does not glow is smaller than the one that emits light, then the umbra is a cone; If it doesn't glow more than it glows, then the umbra is a big round table.

The astronomical community confirms that the Earth's umbra is a cone, indicating that the Earth is smaller than the Sun.

Archimedes said, if you give me some sunshine, I can grow grass, and if you give me a fulcrum, I can lift the earth. Why didn't he say he could lift the sun, because the sun was too big...

It can't be proven. Because you didn't give points. The masters are not coming.

Classical optics can be solved

The first floor is right, all three situations are understood.

The comparison between the size of the Sun and the Earth is as follows.

1. Comparison of the size of the sun and the earth (volume).

The diameter of the Sun is about 1,392,000 kilometers, the diameter of the Earth is about 12,756 kilometers, and the volume ratio is about 1,300,000:1.

2. Comparison of the size of the sun and the earth (mass).

The mass of the Sun is about kilograms, the mass of the Earth is about kilograms, and the mass ratio is about 333400:1.

Definition of the relationship between the sun and the earth.

The Sun-Earth relationship is a general term for the effects of ionospheric and climatic influences. The Sun is a largely stable star with little variation in the total amount of radiation.

However, its outer atmosphere is dominated by the sun's magnetic field and is subjected to localized intense activity, which causes solar radiation to fluctuate greatly in the ultraviolet and X-ray bands.

Sunspots are the most obvious signs of solar activity, followed by light spots, flares, solar and coronal expansion, and the most intense and most impactful of the Earth are flares.

Sun and geomagnetism.

The effect of solar activity on geomagnetism.

The biggest impact is on magnetic storms. There is a typical magnetic storm in the mid- and low-latitude regions.

It can be divided into four different phases, namely the acute beginning, the primary phase, the main phase and the recovery phase. There is also an instantaneous disturbance similar to a sudden magnetic storm, which has a smaller amplitude and less pronounced suddenness, which appears to come from the sudden compression and expansion of the Earth's magnetosphere caused by shock waves or other intermittent sources of interplanetary matter.

In addition, some geomagnetic disturbances have a 27-day recurrence, which is one of the most challenging topics in the relationship between the Sun and the Earth.

This problem has not been solved for a long time since Bartels proposed the existence of the m-region on the Sun as a source of reproducible magnetic disturbance in 1932.

It was not until the seventies that solar X-rays and space probes determined that the source of this continuous emission of low-energy particles (high-speed solar wind) was a coronal hole.

The relationship between solar activity and Earth's climate change Solar radiation and solar activity phenomena cause changes in Earth's climate over time.

Although this causal relationship has not yet been identified, it is certainly related from statistical analysis.

The study of the effects of solar activity on climate has been around for nearly 180 years. In 1801, the British astronomer Herschel first mentioned that when there are fewer sunspots, the amount of rain on the ground also decreases.

This is the earliest discussion of the relationship between solar activity and climate before the discovery of the 11-year cycle of sunspots.

Thereafter, the Swiss astronomer RWolf studied the relationship between the relative number of sunspots and the meteorological elements in the history of the city of Zurich, and found that when sunspots are abundant, the climate is dry and agricultural is abundant, and conversely, when sunspots are few, the climate is humid and rainy.

In recent years, there has been a growing international interest in the study of this issue.

A statistical study of the effects of solar activity on climate change. The relationship between precipitation and the relative number of sunspots in the three different geographical latitudes of the Northern Hemisphere shows that they all have an 11-year cycle.

The relationship between atmospheric circulation patterns and solar activity reflects the 80-year cycle of solar activity. <>

1.The sun is bigger than the earth.

2.The radius of the Sun is about 695,700 kilometers, the radius of the Earth is about 6,371 kilometers, and the Sun is equivalent to 1.3 million Earths.

3.The Sun is 1.3 million times the volume of the Earth.

4.It is 330,000 times more massive than the Earth.

5.It weighs 20 times the weight of the Earth.

6.The Earth is 500 million kilometers away from the Sun, so the Sun is smaller than the Earth when viewed from the ground.

7.The Sun is a huge, red-hot planet of gas.

8.Knowing the distance between the Sun and the Earth, and then measuring the diameter of the angle of view of the sun's circle from the earth, we can find that the radius of the sun is 660,000 kilometers, which is 109 times the radius of the earth.

The diameter of the Sun is equivalent to 109 times the diameter of the Earth, and the volume is about 1.3 million times that of the Earth.

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, 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, which is 109 times the diameter of the Earth; It is about 1.3 million times the size of the Earth; Its mass is about 330,000 times that of the Earth. In terms of chemical composition, about three-quarters of the mass of the Sun is now hydrogen, and almost all of the rest is helium, including oxygen, carbon, neon, iron, and other heavy elements with less than 2% of the mass, which uses nuclear fusion to release light and heat into space.

The Sun is a yellow dwarf, and the lifespan of a yellow dwarf is roughly 10 billion years, and the Sun is currently about 100 million years old. In about 50 to 6 billion years, the Sun's interior will be almost completely depleted of hydrogen and the Sun's core will collapse, causing the temperature to rise, a process that will continue until the Sun begins to fuse helium into carbon. Although helium fusion produces less energy than hydrogen fusion, it is also hotter, so the outer layers of the sun will expand and release a portion of the outer atmosphere into space.

At the end of the process of turning to new elements, the mass of the Sun will decrease slightly, and the outer layers will extend to the current orbit of the Earth or Mars (at which point the two planets will be farther away from the Sun due to the decrease in the mass of the Sun).

The Sun is many times larger than the Earth compared to the Earth. Suppose the sun is reduced to the size of a standard basketball, then the earth is equivalent to a grain of rice, 26 meters from a basketball. The solar system is about a sphere with a radius of 13 kilometers with basketball as the center.

Starting from the Sun, the diameter of the Sun's hidden beam is about 1.4 million kilometers, the diameter of Mercury is about 10,000 kilometers, the diameter of Venus is about 10,000 kilometers, the diameter of the Earth is about 10,000 kilometers, the diameter of Mars is about 10,000 kilometers, the diameter of Jupiter is about 10,000 kilometers, the diameter of Saturn is about 10,000 kilometers, the diameter of Uranus is about 10,000 kilometers, and the diameter of Neptune is about 10,000 kilometers.

Suppose that if human beings want to walk from Tai Scum, Li Yang to the earth, starting from the surface of the sun, and after walking for an hour, human beings will walk to the earth, and if they start from the earth, they will have to walk to the edge of the solar system at the same speed, then human beings will have to walk for another year.

The diameter of the Sun is 109 times that of the Earth. The diameter of an orchid coin for 1 cent is centimeters. If the diameter of the Earth is as large as a 1 dime coin, then the diameter of the Sun is 207 centimeters.

So what kind of existence will the earth be in front of the sun? For example, it's like a standard table for 15 people (2.1 meters in diameter) in a restaurant with a dime coin on it. Isn't the difference between the Earth and the Sun obvious?

Know that this is just a comparison of the diameters of the Earth and the Sun. If it's a comparison in volume, then the gap is even greater. The Sun is 1.3 million times the size of the Earth!

1. The sun is larger than the earth and the earth is larger than the moon in terms of volume.

2. The sun is a star, the largest celestial body in the solar system, the earth is a planet, the only living celestial body in the solar system, compared with the sun, it is like a sesame seed, 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 the volume is naturally smaller than the earth, so the sun is larger than the earth and larger than the moon, in the earth-moon planetary system, the moon revolves around the spring sun, and the earth rotates, so the difference between day and night is formed.

The sun and the earth are not the same size. The sun is large, the sun is much larger than the earth, and the sun is a dominant celestial body with great influence in the solar system.

The Sun is 1.3 million times the volume of the Earth and its mass is about 330,000 times that of the Earth. The average diameter of the earth we live in is about 10,000 kilometers, and the diameter of the sun is actually 10,000 kilometers, which is equivalent to 109 times the diameter of the earth.

The sun is the central body of the solar system and occupies the overall mass of the solar system. The eight planets, asteroids, meteors, comets, outer Neptune objects, and interstellar dust in the solar system all revolve around the Sun, which orbits 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 of hot plasma intertwined with magnetic fields. The diameter of the Sun is about 1,392,000 kilometers, which is 109 times the diameter of the Earth; It is about 1.3 million times the size of the Earth; Its mass is about 2,1030 kilograms (330,000 times that of the Earth).

In terms of chemical composition, about three-quarters of the sun's mass is now hydrogen, and almost all of the rest is helium, including oxygen, carbon, neon, iron, and other heavy elements with less than 2% mass, which is used to release light and heat into space in the careful way of nuclear fusion.

The structure of the sun:

According to the relative intensity of solar activity, the sun can be divided into two categories: the quiet sun and the active sun. The Tranquility Sun is a theoretically assumed spherically symmetrical hot gas sphere whose properties vary only with radius and are uniform in either sphere, with the aim of studying the general structure and general properties of the Sun.

Under this assumption, the Sun is composed of a core, a radiation region, a troposphere, a photosphere, a chromosphere, and a corona, in order from the inside out. Below the photosphere is called the interior of the Sun; Above the photosphere is called the solar atmosphere. <>

The Sun is the core of the Solar System and the largest planet in the Solar System. The volume of the Earth simply cannot be compared to that of the Sun.

In the solar system, the Earth is just a planet of inferior mass. If we have to compare the sun with the earth, the sun has 330,000 times the mass and 1.3 million times the volume of the earth. In other words, 1.3 million Earths could be placed inside the Sun.
