Why is the sun bigger than the earth, the sun is bigger or the earth is bigger

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.

How much bigger is the Sun than the Earth?

1.3 million times.

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 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, 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.

In our lives, many people don't know much about geography, so let's popularize which is bigger than the sun and the earth.

Introduction to the Sun

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 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 (km), and its mass is about 2 10 kilograms. In terms of chemical composition, the sun now has about three-quarters of its mass of 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, using nuclear fusion to release light and heat into space.

Introduction to the Earth

Earth is one of the eight planets in the solar system, the third in order of near and far from the sun, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun. The equatorial radius of Zheng Zhaoqiu is 1 kilometer, the polar radius is 10000 kilometers, the average radius is about 6371 kilometers, and the circumference of the equator is about 40076 kilometers. The surface area of the earth is 100 million square kilometers, of which 71% is oceans and 29% is land.

Therefore, compared with the earth, the sun is much larger than the earth, and 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. However, because the earth is 100 million kilometers away from the sun, the sun is smaller than the earth when viewed from the ground.

The sun is bigger than the earth.

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. The Sun is 1.3 million times the volume of the Earth, 330,000 times the mass of the Earth, and 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.

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.

Effects of solar radiation on the Earth

Solar radiation energy is the main driving force for maintaining the earth's surface temperature and promoting water, atmosphere, and biological activities and changes on Earth. Different latitudes on the ground receive different solar radiation, and the heat transfer on the earth mainly depends on atmospheric circulation and ocean currents, which play an important role in the formation and change of the geographical environment.

Solar radiation energy is the main energy source for our production and life. Some of them come directly from solar energy, such as solar power generation, solar cookers, solar dryers to process agricultural and sideline products, etc. The other part is the energy converted from solar energy, such as coal, oil and other fossil fuels.

The Sun was at the center of the mass of matter that formed the solar system when it was formed. It also has a large centrosome, which can concentrate the surrounding interstellar matter due to its large gravitational pull. So the volume is large. The Earth is on the edge, all the interstellar matter is less, and the Earth's gravitational force is small, so the volume is naturally small.

Because the Sun is formed by the gravitational contraction of the central part of the interstellar gas cloud, which has the highest density and the most concentrated matter.

The solar system is produced from the same huge cloud of interstellar gas. When the gravitational contraction of this cloud of interstellar gas, a sphere with a high density in the center and thinner towards the edges is formed, and then a discus shape is formed through the centrifugal force generated by the rotational motion. Because the central part of the matter is the densest and the gravitational pull is the strongest, the final formation of a central celestial body that accounts for most of the matter of the interstellar gas cloud, which is the sun.

In the sparse part of the edge, a series of low-mass objects are formed by gravitational contraction, namely planets including the Earth and their moons.

As a result, the Sun occupies more than 99% of the total mass of the solar system, while planets other than the Sun and their moons account for less than 1% of the total mass of the solar system.

If the sun were small, there would be no earth.

When it was not transformed into the sun, it was still a black hole.
