330,000 times. Sun kilograms.

Earth kilograms.

The volume of the Sun is about 1,300,000 times that of the Earth;

The mass of the Sun is 330,000 times that of the Earth.

The volume of the Sun is the Earth's Sun is the most striking object in the sky, it is a star located in the center of the solar system, and its apparent magnitude is equal (the magnitude of the star is divided according to the amount of stellar light received on the Earth is called "apparent magnitude", and the brightness decreases with the increase of the magnitude number, the zero magnitude star is brighter than the first magnitude, and the negative magnitude star is brighter than the zero magnitude), 500,000 times brighter than the Moon (the Moon has an apparent magnitude of 12 8). The diameter of the Sun is 1.39 million kilometers, which is 109 times that of the Earth and 400 times that of the Moon. The Sun is 1.3 million times the volume of the Earth, 330,000 times the mass of the Earth, and has an average density of grams3.

The Sun weighs 270 times more than 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, a huge nuclear reaction zone is formed, its composition is hydrogen and helium, and when hydrogen is converted into helium, a huge amount of energy can be released, which is the nuclear fusion reaction. The energy released in the nuclear fusion reaction is radiated 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 mass of the Sun is 330,000 times that of the Earth.

Solar mass is a unit of mass used to measure the mass of a star or large celestial body such as a galaxy, and its size is equal to the total mass of the Sun, which is about kilograms high (usually kilograms). In terms of volume, the volume of the sun is 1 million times that of the earth, which means that a sun can hold more than 1 million earths.

The average density of the sun is grams per cubic centimeter, but the density of the sun is not the same inside and outside. Its shell is mostly gaseous and has a very low density. But the further inside, the denser and denser the substance becomes.

The density of the core may be 160 grams per cubic centimeter, which is nearly 20 times greater than the density of steel.

The distance from the Sun to the Earth

In 1672, scientists had already calculated the distance from the sun to the earth. According to the detection, the earth's revolution is an elliptical type, eccentricity only, and the final calculation shows that the closest distance between the earth and the sun is 100 million kilometers, and the farthest distance is 100 million kilometers, so the average distance from the sun to the earth is 100 million kilometers, which is commonly represented by the astronomical unit "au".

As far as we humans are concerned, the Sun is far enough away from the Earth, but it is very close to light, it only takes 499 seconds to travel from the Sun to the Earth, which is a light-year in terms of light years. In this way, the Andromeda Galaxy is 2.54 million light-years away from the Milky Way.

330,000 times.

The mass of the Sun is nearly 200 billion trillion tons, 330,000 times that of the Earth.

It is about 1.3 million times the size of the Earth, and has a radius of about 700,000 kilometers, which is more than 109 times the radius of the Earth.

About 33,000 times. The Sun is the central body of the solar system and accounts for 10 percent of the total mass of the solar system. The eight planets in the solar system, such as macroplanets, 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 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 percent mass, using nuclear fusion to release light and heat into space.

I don't know how many times the volume of the sun is the earth, so let's take a look! The following is carefully prepared by me for you "how many times the volume of the sun is the earth", this article is for reference only, continue to pay attention to this site will continue to get more information!

How many times the volume of the Sun is the Earth

The Sun is a huge, red-hot planet of gas. 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, from the simple triangular relationship of the Zhiye, we can find that the radius of the sun is 10,000 kilometers, which is 109 times the radius of the earth. From this, it can be calculated that the volume of the Sun is 1.3 million times that of the Earth.

Further reading: What is the external structure of the sun from the inside to the outside

The solar atmosphere is divided into three layers: the photosphere, the chromosphere, and the corona from the inside to the outside. The solar photosphere is above the convective region of the sun, and the atmosphere above the photosphere is the chromosphere, and the corona is the outermost layer of the solar atmosphere.

What is the effect of solar activity on the Earth

1. Disrupt the earth's atmosphere, so that the radio short-wave communication on the ground will be affected, and even there will be a short interruption.

2. High-energy charged particles disturb the earth's magnetic field, producing a "magnetic storm" phenomenon, which makes the magnetic needle vibrate violently and cannot indicate the direction correctly.

The whole earth is a large magnetic field, magnetic storms generally occur 20-40 hours after the eruption of solar flares, it is a strong disturbance of the geomagnetic field, and the strength of the magnetic field can vary greatly.

3. Aurora will occur when the stream of high-energy charged particles rushes into the high-altitude atmosphere of the polar regions at high speed.

4. Cause natural disasters, such as floods and droughts.

In what direction the sun rises in winter

In winter, the sun rises in a south-easterly direction and sets in a south-westerly direction; In summer, the sun rises and sets in a north-east and north-west direction, respectively. Where the latitude is different, the degree of "tilting" of the sun's trajectory is also different. The two points where the celestial equator intersects the horizon are due east and west.

As you can see, the sun rises in a north-east direction and sets in a north-west direction on the summer solstice.

What is the principle of the formation of a total solar eclipse

A total solar eclipse occurs because the three celestial bodies, the Sun, the Moon and the Earth, happen to be very close to a straight line at a specific moment, and the Moon moves between the Sun and the Earth and obscures the Sun. When a total solar eclipse occurs, the Moon's shadow on the Earth is divided into two parts, the central area is called the umbra ridge and the outer area is called the penumbra. A total solar eclipse can only be seen from the position of the umbra.

The volume of the Sun is about 1.3 million times the volume of the Earth, but as the Sun ages, it will grow larger and larger in the future, and in old age, its volume will increase by nearly 100 million times on the current basis, which will be equivalent to the volume of 100 trillion Earths.

Effects of solar activity on the Earth:

1. Aurora phenomenon.

In the polar regions close to the Earth, it is common to see colorful and varied bands of light shining in the sky at night, which is called the aurora. Aurora is a high-energy physical phenomenon produced by the high-speed charged particle stream emitted by the hail buried in the sun's hair shed and the interaction with the high-altitude atmospheric molecules in the polar regions of the earth under the action of a magnetic field. Observations have shown that the intensity and frequency of auroras are closely related to the intensity of solar activity.

2. Earth magnetic storms.

A phenomenon of 11-year or longer cycle activity that exists on the Sun. Whenever the relative number of sunspots increases in the peak year of solar activity, flare eruptions, coronal material ejections and other phenomena occur frequently, and a large number of high-energy charged particles are emitted to reach the earth, the original magnetic field of the earth will be disturbed, causing the earth's magnetic storm.

3. Impact on radio communication and electricity.

When the sun emits a large number of high-energy charged particles into near-earth space, it will interfere with radio communications and ground power transmission, and when a large-scale explosive activity event occurs on the sun, the relevant departments need to be prepared to take countermeasures.

4. Impact on astronautics.

The flow of high-energy charged particles can also interfere with and destroy the equipment and operation of the space-chain sail detector, and even threaten the life safety of astronauts, so the space exploration equipment must fully consider this factor, have a detailed understanding of the magnetic field conditions and solar wind conditions near the earth and the route area, and consider the preventive measures.

5. Impact on earth disasters.

The impact of solar activity on some catastrophic events on Earth has been a long-term concern of many scientists. The data show that the solar activity cycle has a certain relationship with the changes of floods and droughts and cold and warm changes on the earth. For example, studies have shown that the number of years of flooding, drought, cold and warmth, and the number of occurrences are related to the 11- and 22-year cycles of solar activity.

6. Impact on the human body.

Statistical studies of astronomical factors and human health and behavior have found that the human nervous system is very sensitive to changes in solar activity during the Earth's magnetic storms caused by solar activity, and certain diseases, changes in the blood system, nervous system and sunspot activity show obvious correlations. At present, such topics are still in the research stage.
