![]() A magnetic storm occurs, which can manifest itself in the form of auroras borealis. When such particles or plasma reach our planet, they interact with its magnetic field and atmosphere. This phenomenon is called coronary ejection. Sometimes a large piece of plasma can even break away from our star. Usually its intensity is too weak to harm people on Earth.īut during solar flares, a large number of charged particles can be emitted. The Sun’s magnetic field is constantly accelerating charged particles called the solar wind. Solar wind can cause magnetic storms on Earth To study these processes, the Solar Orbiter device was launched. Because of this, powerful plasma emissions, called solar flares, occur in such areas. Sunspots are areas on the surface of the Sun where the lines of force of its magnetic field are twisted and torn. You can’t just look at our luminary through a telescope, but if you use dark filters, large groups of spots are visible. The layer of the Sun’s surface that emits visible light is called the photosphere. The solar corona can be seen from Earth by observing our luminary during its total eclipse. However, sometimes there are some even hotter spots in it, the temperature of which can reach 20 million degrees Kelvin. Its average temperature is 1-2 million degrees Kelvin. The solar corona is one of the hottest parts of our world. ![]() ![]() Usually these formations are hundreds of thousands of kilometers long, ie they are longer than the distance from the Earth to the Moon. It consists of protuberances and various plasma eruptions. The solar corona (Latin for “crown”) is the outer layer of our luminary. Comparing the sizes of the Sun and its planets. At the same time, the density of our star is about 40 percent higher than that of water. Our luminary could hold 1.3 million terrestrial planets inside. Even the mass of Jupiter is only one thousandth of the mass of our luminary.Īs for the Earth, it is about 333 thousand times lighter than the Sun. This means that it weighs about 500 times more than all the planets and asteroids combined. The sun makes up 99.866 percent of the mass of the solar system. The mass of the Sun is 500 times greater than that of all the planets around it Helium is the element named after the Sun. It is due to the thermonuclear reaction that converts hydrogen into helium that our luminary produces energy. Another 73 percent is hydrogen, and the rest are heavier elements. Helium constitutes about a quarter of the Sun. This substance was later found on Earth as well, but the name remained. For some time it was believed that it was present only there, so it was named after the Greek god of the Sun-Helios. When people first tried to determine the chemical composition of our star by its spectrum, they saw the lines of radiation of an unknown element. The element helium got its name from the Sun. Maybe the other stars are also suns for some creatures. In addition, it is a benchmark for us - it is by observing it, that we judge as for the nature of other similar objects. ![]() Therefore, the Sun is actually bigger than 90 percent of the stars in its vicinity. The distribution of luminaries of different sizes is not uniform across the universe. Yellowish color emerges when its rays pass through the Earth’s atmosphere. Due to this, the spectrum of its radiation is almost white. Our luminary is a typical G-class star in the middle of its life cycle. It is located at a distance of almost 150 million km from us. The sun is a giant plasma ball, inside which thermonuclear reactions take place. A selection of 12 facts about our closest star neighbor- the Sun.
