Understanding the Sun and Its Energy

The video explains that the closest star to Earth is the Sun, also known as Sol. It highlights the Sun's importance as the energy source for our solar system. The Sun is a massive, hot ball of gas, with a core temperature of about 15,000,000°C. Its energy takes over 100,000 years to travel from the core to the surface, but only eight minutes to reach Earth as light and heat. This energy is crucial for life on Earth, preventing it from becoming a frozen, lifeless planet.
