Questions and answers about how the sun is composed

• What is the sun made of

  The sun is mainly composed of hydrogen and helium, accounting for 74.9% and 23.8% of the mass of the solar photosphere respectively. Other heavy elements, that is, elements with larger atomic weights, account for less than 2% of the total mass of the sun. The more abundant heavy elements are oxygen (about 1% of the sun's mass), carbon (0.3%), neon (0.2%) and iron (0.2%).

• What is the sun made of?

  Composition of the sun There are more than 90 chemical elements in the solar atmosphere. The content of hydrogen is the largest, accounting for about 71% of the solar mass, helium for about 27%, and other elements for about 2%. Other elements include sodium, calcium, iron, oxygen, etc. Its average temperature is about 6000 degrees Celsius, which can be said to be a very high temperature atmosphere. The high temperature on the sun keeps matter in a gaseous state, but also makes gas atoms lose a lot of extranuclear electrons, which are no longer bound by the protonucleus

• What is the sun made of

  The solar atmosphere consists of three layers: the photosphere, the chromosphere and the corona. Like many other stars, the sun is a gaseous sphere. At present, hydrogen accounts for about 71% of the sun's composition, helium accounts for about 27%, and other elements account for 2%. The light and heat emitted by the sun are mainly produced by hydrogen nuclear fusion.

• What is the chemical composition of the sun?

  Kirchhoff analyzed the chemical composition of the sun. After German chemist Kirchhoff and Bunsen invented the spectral analysis technology, they used it to study the solar spectrum. After analysis, it is found that the sun contains Hydrogen, calcium, sodium, iron and other common elements on the earth have caused great shock to the world. Since then, spectral analysis technology has become an important technology for discovering new elements.

• What is the sun made of?

  In the vast universe, although the sun is only a very common star, it is the source of our human activities. In the vast world of stars, the brightness, size and material density of the sun are at the medium level. Just because it is close to the earth, it seems to be the largest and brightest celestial body in the sky. Other stars are very far away from us. Even the nearest star is 270000 times farther than the sun, so it looks like a twinkling light spot. Sun

• What does sunlight consist of?

  Sunlight consists of "Y ray, X ray, ultraviolet ray, visible ray and infrared ray". The light that can be seen with the eyes, such as the seven colors of the rainbow, is visible light. The ultraviolet light with a shorter wavelength than the purple visible light is called ultraviolet UV. UV can also be divided into UVA (320~400 nm), UVB (280~320 nm) and

• Why is the light of the sun composed of seven colors?

  It is not because the sunlight is divided into seven colors. The color is just the feeling of the human eye. The human eye reacts to the electromagnetic wave with the wavelength of 400 nm to 760 nm, and as the wavelength becomes shorter, the feeling changes from red, orange, yellow... to purple.

• What is the composition of the sun

  In terms of chemical composition, about three quarters of the sun's mass is hydrogen, and the rest is almost helium, including oxygen, carbon, neon, iron and other heavy elements, whose mass is less than 2%, of which hydrogen accounts for 71.3% and helium for 27% It is almost an ideal sphere interwoven with thermal plasma and magnetic field. From the center outwards, it can be divided into nuclear reaction zone, radiation zone and convection zone, and solar atmosphere. The atmosphere of the sun, like the atmosphere of the earth, can be adjusted according to different heights and

• How long can the sun burn?

  The hydrogen fuel in the core of the sun can continue to fuse for about 5 billion years, which means that the sun can still exist as a stable main sequence star for 5 billion years. After that, with the depletion of hydrogen in the core, helium fusion reaction will appear in the core, and hydrogen fusion reaction will appear in the outer circle. The brightness of the sun will be greatly reduced, but the size will be significantly increased. Its outer circle will reach near the current Earth orbit, become a red giant star, and exist in the form of a red giant star for about 1 billion years. Helium in the central area

• How the sun was formed

  The sun is a big gas sphere containing 20 billion tons of gas. The sun burns these gases and emits light and heat. About 5 billion years ago, a huge star exploded in the Milky Way, forming interstellar space, As a result of gravity, the interstellar cloud continuously shrinks, and the mass concentrates to a center, forming a saucer shaped air mass. The temperature and pressure of the air mass rise rapidly. When it reaches several million degrees, the center ball begins to produce nuclear fusion reaction, releasing huge energy, producing

• What gases make up the sun's nuclear reaction?

  The interior of the sun can be divided into three layers: the core, radiation and convection The sun's energy comes from its core. The core temperature of the sun is as high as 15 million degrees Celsius, and the pressure is equivalent to 250 billion atmospheres. The gas in the core area is extremely compressed to 150 times the density of water. Nuclear fusion is taking place here, and 700 million tons of hydrogen is converted into helium every second. In this process, about 5 million tons of net energy is released (about 38600 tons)
