The volume of the Sun is about 10 18 cubic kilometers (1,300,000 times that of the Earth) and its mass is about kilograms (333,400 times that of the Earth).
The total mass of the entire solar system is concentrated in the sun, so much material makes the sun a well-deserved king of volume in the solar system, and it is also the only star in the entire solar system, with a diameter of about 13.92 million kilometers, and its volume is about 1.3 million times that of the earth.
Characteristics of the sunThe sun uses nuclear fusion to release light and heat into space, which is the source of light and heat for the planets. The main signs of solar activity are sunspots and flares. Flares are the most intense display of solar activity.
On the Earth's climate precipitation, ionosphere, magnetic field there is a phenomenon of "magnetic storms" and in the night sky at high latitudes there are auroras. On the photosphere of the Sun, there are some swirling air currents, like a shallow disk, concave in the middle, which appear to be black, and these vortex air currents are sunspots.

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.

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 .

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.

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).
There is no way to estimate the gravitational pull of the Sun in an exact number, but what we do know is that the Sun is the core of the entire solar systemAll the planets in the solar system revolve around the sun or are affected by the sun's gravity, and at least eight planets are strictly bound by the sun's gravity. <> >>>More
Stars originally evolved from relatively large blocks in nebulae. If you think about gravity, you can create a scenario in your brain, which is kind of like a snowball. If you have snowballed, it is not difficult to understand why the stars are round. >>>More
How long does the sun have to live?
Gravitational forces cause it to be circular, and the maximum time to see the Sun on Earth is at perihelion, which is January.
At present, the Nebula theory is the dominant view. For more information, please refer to the encyclopedia.
