Why is the sun bigger and brighter than any other star? As the sun is one of the most important components of the solar system, and it plays a role in supplying the planet with energy, in addition to providing the moon with light, to shine at night, and many other benefits of the sun in the universe, but what is important in this article is to know the structure of the sun, and why the sun appears larger and brighter than any other star. The sun The sun is one of regarding 100 billion stars in the Milky Way, and the sun has very important effects on the planet, as it affects weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis, and without the sun’s heat and light, why does life exist On the ground. About 4.5 billion years ago, the Sun began to form from a molecular cloud consisting primarily of hydrogen and helium. Hydrogen and helium lie at the center of this hot spinning mass, and eventually the gases are heated enough to begin nuclear fusion, becoming the solar system’s sun. Why is the sun bigger and brighter than any other star? The sun is very big compared to the earth, however, compared to other stars, the sun is just a medium-sized star, and some stars are much larger than the sun and some are much smaller, and the sun appears larger and brighter than other stars because it is much closer to the earth, so the more it is The farther away the thing is, the smaller it appears, even if it is very large. The structure of the sun Now that we know why the sun appears larger and brighter than any other star? It is important to know the structure of the sun, as the sun consists of hydrogen and helium, which are the two main components of the sun, as these two elements came from the Big Bang process and make up 98% of the mass of the sun. The sun, and the remaining percentage is calculated through some elements, namely oxygen, carbon, neon, iron, magnesium, nickel, chromium, silicon, and sulfur. The sun also has six layers, namely the core, radiation zone, convection zone, photosphere, chromosphere, and corona. The following is an explanation of each layer: Core: The size of the core of the sun is a thousand times larger than the size of the Earth, and it is ten times more dense than lead. The core of the sun is a huge furnace, with temperatures in the core exceeding 15.7 million degrees Celsius, and the core extends. About 25% of the Sun’s radius, the core is the only place where nuclear fusion reactions can occur, and the other layers of the Sun are heated by the nuclear energy generated there. Radiant field: The radiation zone of the Sun begins at regarding 25% of the radius, and extends to regarding 70% of the radius. In this wide region, the heat of the core is greatly cooled from between seven million K to two million K, and in the radiation region the energy is transferred through a process called thermal radiation. The photosphere or the photosphere: The photosphere is the visible surface of the sun with a light yellow color, where the thickness of the photosphere is regarding 400 km, and the temperatures there reach regarding 5700 degrees Celsius, and the thermal columns of the convection zone appear in the photosphere. Chromosphere: The red chromosphere is regarding 2,000 km thick and filled with jets of hot gas, where it meets at the bottom of the chromosphere, and the sun is at its coldest at regarding 4,100 ° C, as this is lower. Temperature gives the chromosphere a red color, and the temperature in the chromosphere increases with altitude, reaching 25,000 °C at the outer edge of the region. The chromosphere releases jets of burning gases called spicules. Halo: It is the tenuous outermost layer of the solar atmosphere, and can extend millions of kilometers into space. The gases in the corona burn regarding a million degrees Celsius, moving regarding 145 kilometers per second. At the end of this article, we will have known the answer to one of the questions, why is the sun bigger and brighter than any other star? The most important benefits of the sun, its properties and general structure, as well as its components, were also discussed.
