Suns - 10 things to know with detail

• The sun is a star located at the center of our solar system. It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process.
• The sun's diameter is about 1.39 million kilometers, which is approximately 109 times the diameter of Earth. Its mass is about 330,000 times that of Earth.
• The sun is composed mainly of hydrogen (about 74%) and helium (about 24%) with trace amounts of heavier elements such as oxygen, carbon, neon, and iron.
• The sun's energy comes from nuclear fusion reactions in its core, where hydrogen atoms are fused together to form helium, releasing a tremendous amount of energy in the process.
• The sun's surface temperature is about 5,500 degrees Celsius (9,932 degrees Fahrenheit), while the temperature in its core reaches about 15 million degrees Celsius (27 million degrees Fahrenheit).
• The sun emits energy in the form of electromagnetic radiation, including visible light, ultraviolet light, and infrared radiation. This energy is essential for life on Earth as it provides warmth and light.
• The sun has an 11-year solar cycle, during which its magnetic activity fluctuates, leading to changes in the number of sunspots and solar flares. This cycle affects space weather and can cause disruptions to satellite communications and power grids on Earth.
• The sun is about 4.6 billion years old and is roughly halfway through its main sequence phase, during which it fuses hydrogen into helium in its core. Eventually, the sun will exhaust its hydrogen fuel and evolve into a red giant before shedding its outer layers to form a planetary nebula.
• The sun's gravity is responsible for keeping the planets in orbit around it, as well as maintaining the shape of the solar system. Its gravitational influence extends far beyond the orbit of Pluto, encompassing the entire Oort Cloud.
• Studying the sun is crucial for understanding stellar evolution, solar physics, and space weather. Scientists use telescopes, satellites, and ground-based observatories to observe the sun in different wavelengths of light and study its various phenomena, such as solar flares, coronal mass ejections, and sunspots.
