Key insights

• 🌞 The Sun formed about 4.5 billion years ago from a collapsing solar nebula in the Milky Way's Orion's fur.
• 🔥 The Sun consists of six layers, mainly composed of hydrogen and helium, with extreme temperatures creating a plasma phase. The core reaches at least 27 million degrees Fahrenheit.
• 💥 Thermonuclear fusion in the Sun releases energy in different forms such as radiation, electricity, and heat. Its gravity holds the solar system intact due to its size and mass.
• 🪐 The Sun contains approximately 99.8% of all the mass in the solar system and has a gravitational force that holds planets, moons, and other celestial bodies in its orbit.
• 🌌 The Sun's gravity forms the heliosphere, protecting planets from cosmic radiation. Its magnetic field interacts with planets' atmospheres, causing beautiful auroras.
• ⏳ In 6.5 billion years, the Sun will run out of fuel, expand, and collapse into a white dwarf. Its magnetic field, gravitational pull, and energy creation are vital for sustaining life in the solar system.
