The Sun is middle-aged. At around 4.6 billion years old, the Sun has already burned off about half of its store of Hydrogen. It has enough left to continue to burn Hydrogen for approximately 5 billion years. , The hottest part of the Sun, The hottest part of the Sun is its core, where temperatures can reach 15 million degrees Celsius, Energy is generated at the Sun’s core, by nuclear fusion, as Hydrogen converts to Helium. Hot objects expand, the Sun would explode if it were not for its enormous gravitational force. The temperature on the surface of the Sun is closer to 5,600 degrees Celsius. Solar wind can cause magnetic storms on Earth., The Sun’s magnetic field is constantly accelerating charged particles called the solar wind. Usually its intensity is too weak to harm people on Earth. But during solar flares, a large number of charged particles can be emitted. Sometimes a large piece of plasma can even break away from our star. This phenomenon is called coronary ejection. When such particles or plasma reach our planet, they interact with its magnetic field and atmosphere. A magnetic storm occurs, which can manifest itself in the form of auroras borealis. Such storms can cause failures of electrical and radio equipment, and indispose people with chronic diseases. The Sun contains 99.86% of the mass in the Solar System. One million Earths could fit inside the Sun. The mass of the Sun is approximately 330,000 times greater than that of the Earth. It is almost three-quarters hydrogen, while most of the remaining mass is helium.
