How big is the area of the sun, and how big is the area of the sun

The 390,000 Sun is the largest object in the solar system. It has the entire mass of the solar system (Jupiter has most of the remaining mass). The sun is personified in many myths:

The ancient Greeks called it helios, while the ancient Romans called it sol. The mass of the Sun is composed of 75% hydrogen and 25% helium (the atomic number is hydrogen, which is helium); Other substances ("Metals") is only the sum of the totals. In the core of the Sun, hydrogen is converted to helium, and these amounts change slowly.

The outer layers of the Sun have different rotation periods: the equatorial plane rotates once in the sky; In the polar regions, it reached 36 days. This peculiar phenomenon arises because the Sun is not a solid sphere like Earth, and a similar situation can be seen on gaseous planets.

Therefore, in the interior of the Sun, the rotation period is also different, but the core of the Sun still rotates like a solid body. The state of the Sun's inner core is staggering, with a temperature of 15,600,000 Keliton and a pressure equivalent to 250 billion atmospheres. The gas in the inner core is so compressed that it is 150 times denser than water.

The Sun releases energy in erg seconds (i.e. 3,860 billion trillion megawatts), which is produced by nuclear fusion reactions. Approximately 700,000,000 tons of hydrogen atoms are converted into approximately 695,000,000 tons of helium atoms per second and 5,000,000 tons (erg) of energy in the form of gamma rays. Because the rays are emitted to the surface of the sphere, the energy is constantly absorbed and dissipated, so that the temperature is constantly lowered, so there is a huge temperature difference between the inside and outside and the basic visible light.

The energy output by convection is at least 20% higher than the energy diverged by radiation. The outer surface of the Sun is called a photosphere and has a temperature of about 5,800 kilo. Sunspots belong to the "cooler" part of the sun, at only 3800 kai (they look darker because of the comparison to the surrounding area).

Sunspots can be very large, up to 50,000 kilometers in diameter. Sunspots arise as a result of complex and currently unknown interactions from the Sun's magnetic region. A small area above the ball of light is called a chromosphere.

The vast and thin material above the chromosopher, called the halo, stretches millions of kilometers into space, but it can only be observed during a solar eclipse (left). The internal temperature of the solar halo is more than 1,000,000 open. The Sun's magnetic field exerts tremendous forces (by Earth standards) and is complex.

Its magnetospheric extent even greatly exceeds that of Pluto. In addition to light and heat, the Sun also emits a low-density stream of particles (mostly electrons and protons) to form the solar wind, which travels through the solar system at a speed of 450 kilometers per second. When solar wind and high-energy particles flash on the Sun, they affect the tides and radio communications on Earth, resulting in auroras.

It is more than 1.3 million times the volume of the Earth and is the central body of the solar system. An ordinary star in the Milky Way. With an average distance of 149.6 million kilometers and a diameter of 1.39 million kilometers, it takes more than 3,500 years to walk from the earth to the sun, even if you take an airplane, it will take more than 20 years.

The average density is grams of cubic centimeters, the mass of grams is grams, the surface temperature is 5770, and the core temperature is 15 million. From the inside to the outside, they are the solar nuclear reaction zone, the solar troposphere, and the solar atmosphere. Thermonuclear reactions are constantly taking place in its central region, and the energy produced is radiated into space.

One in 2.2 billion of the energy radiates to the earth, becoming the main source of light and heat on the earth. Stars also have their own life histories, from birth, growth, aging, and eventually death. They come in different sizes, colors, and evolutionary journeys.

The star's connection to life is not only manifested in the fact that it provides light and heat. In fact, the heavy atoms that make up planets and living matter were created during the explosions that occurred at the end of the lives of some stars.

It doesn't matter if it's cloudy and windy, or thunder and rain, the sun rises every day, but sometimes it hides in places we can't see, so how big is the sun that appears every day?

The sun rises every day.

The Sun is the first central celestial body of the solar system and occupies the overall mass of the solar system. The eight planets, asteroids, drift fractures, comets, outer Neptune objects, and interstellar dust in the solar system all revolve around the Sun, and the Sun revolves around the center of the Milky Way, orbiting the galactic center at a speed of 250 kilometers per second, and it takes about 100 million years to make one revolution. The sun is also rotating, at the equator, it takes days to rotate the sun for one week, at latitude 40, and at the poles, it takes about 35 days for one rotation.

When the sun rises and sets, the earth rotates around the sun and rotates by itself, which is one day. The earth is constantly turning, that is, the sun rises every day, and the sun cannot be seen on a cloudy day, but a certain part of the earth is blocked by clouds and cannot be seen.

How big is the sun?

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 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.

How hot is the sun?

The Sun is a hot gas planet that glows on its own, with a surface temperature of about 6,000 and a center temperature of up to 15 million.

The square kilometer of the sun is about square kilometers. The Sun is a sphere with a diameter of about 1,392,000 kilometers and a radius of 696,000 kilometers.

It's about 6087350987525 square kilometers. Written as a scientific notation, it is a square kilometer. The Sun is a sphere with a diameter of about 1,392,000 kilometers and a radius of 696,000 kilometers.

The surface area of the sphere is: 4 r 2 so the surface area of the sun is: 4 r 2 = 4 (696000 .

Question 1: What is the total area of the sun, the size of several Earths Because of the sphere, whoever has a larger radius will have a larger surface area. The sun and the earth are both spheres, and the radius of the sun is larger than that of the earth (108 times), so the area of the sun is larger than that of the earth.

Question 2: How big is the area of the sun? The diameter of the sun = 1,392,000 km = 10,000 km So the area of the sun = d 2 = 100 million square kilometers.

Question 3: What is the total area of the sun, the size of several Earths Because of the sphere, whoever has a larger radius will have a larger surface area. The sun and the earth are both spheres, and the radius of the sun is larger than that of the earth (108 times), so the area of the sun is larger than that of the earth.

Question 4: How many times is the surface area of the Sun and the Earth? Note:

It's the area! The radius of the Sun is times that of the Earth, about 695,000 km; The surface area is about 12,000 times the surface area of the Earth, which is about 6,10,12 square kilometers, or 6 trillion square kilometers.

Question 5: How big is the area of the sun? The diameter of the sun = 1,392,000 km = 10,000 km So the area of the sun = d 2 = 100 million square kilometers.

Under the condition that the distance between the Sun and the Earth is known, the volume of the Sun can be calculated as long as the opening angle of the diameter of the apparent circle of the Sun is measured by the instrument. The radius of the Sun is estimated to be about 700,000 kilometers, which is 109 times the radius of the Earth (6,371 kilometers). The volume of the Sun is about 1,41018 cubic kilometres, which is 1.3 million times the volume of the Earth.

Under the condition that the distance between the sun and the earth and the volume of the sun are known, the mass of the sun can be indirectly estimated by the law of gravitation. The mass of the Sun is about 2,1030 kilograms, which is 330,000 times the mass of the Earth (6,1024 kilograms).

From the volume and mass of the Sun, the density of the Sun can be deduced, and its average value is 1 41 g cm3, which is only 1 4 of the density of the Earth (5 52 g cm3).
