13 Lakh Earths Can Fit Inside The Sun! 10 Mind-Blowing Facts About The Sun Did you know that 1.3 million Earths can fit inside the Sun? The Sun is not just a ball of fire, it's a giant nuclear reactor that holds 99.8% of our entire solar system's mass! In this video, we will explore 10 mind-blowing facts about our Sun: 1. Giant Size: The Sun's volume is 1.412 x 1018 km3. About 1.3 million Earths can fit inside it, and its diameter is 109 times bigger than Earth. 2. Huge Mass: The Sun's mass is 1.989 x 1030 kg, which is 333,000 times the mass of Earth. 3. Composition: The Sun is made of 73% Hydrogen and 25% Helium. It was first proved by Cecilia Payne-Gaposchkin in 1925. 4. Nuclear Fusion Factory: The Sun fuses 620 million metric tons of hydrogen into helium every second in its core. This is where its energy comes from. 5. Extreme Temperatures: Core temperature is 15 million Kelvin, while the surface (Photosphere) is only about 5,800 K. The outer Corona is even hotter, 1-2 million K! 6. Layered Structure: The Sun has 7 layers - Core, Radiative Zone, Convective Zone, Photosphere, Chromosphere, Transition Region, and Corona. 7. Insane Distance: The Sun is on average 149.6 million km away from Earth (1 AU). Its light takes 8 minutes and 20 seconds to reach us. 8. The Sun is NOT on Fire: The Sun does not burn like wood. It shines due to nuclear fusion, not chemical combustion. 9. Future of The Sun: The Sun is 4.6 billion years old and is a middle-aged star. After 5 billion years, it will become a Red Giant and then a White Dwarf. 10. The Source of Life: Without the Sun's energy, there would be no life, no wind, no weather on Earth. Watch till the end to know what would happen if the Sun disappeared for just 1 second! #Sun #SunFacts #SolarSystem #NASA #SpaceFacts #ScienceFacts #SunVsEarth
