The Sun is the star at the center of our solar system. It gives us light, heat, and helps life grow on Earth. Let’s learn about the Sun, what it’s made of, and how it affects our planet!

  •  The Sun is a huge ball of hot gases that provides light and heat to Earth.
  •  It’s mostly made of hydrogen and helium gases that burn very hot.
  •  The Sun helps plants grow, gives us warmth, and makes our day bright.
  •  The Sun is incredibly hot! Its core can reach temperatures as high as 27 million degrees Fahrenheit!
  •  Sunspots are dark patches on the Sun’s surface where it’s a little cooler.
  •  The Sun’s energy makes the Earth warm enough for us to live, but too much energy can also cause problems like sunburns.
  • The Sun’s Role in the Solar System: The Sun keeps all the planets in orbit around it, including Earth!

How does sunscreen work?

Sunscreen protects skin by absorbing or reflecting harmful UV rays. It contains ingredients that form a barrier, preventing skin damage, premature aging, and sunburns.

How Do Sun Produce Light?

The Sun produces light through nuclear fusion in its core, where hydrogen atoms fuse into helium, releasing vast amounts of energy, including light and heat.

Life of a Star : Birth & Death of Stars

Stars are born from gas clouds, fusing hydrogen into helium. They grow, burn through fuel, and eventually die, creating novas, black holes, or white dwarfs.

Why is the Sun hot?

The Sun is hot because of nuclear fusion occurring in its core, where hydrogen atoms fuse into helium, releasing immense energy that heats the Sun’s surface.
