Why is the sun so important?

Think Earth is the most important spot in the solar system? The sun is the real star of the show – literally! The closest star to Earth, it’s the source of all our heat and light. Life wouldn’t exist without it. It’s also the center of our solar system and by far its largest object. Our star’s enormous gravitational pull grips the planets, dwarf planets, asteroids, and comets, keeping them from spinning into deep space. Put simply, we wouldn’t have a solar system without the sun.

Scientists estimate the sun has at least another 5 billion years before it turns into a red giant and swallows up Mercury and Venus. It will also destroy all life on Earth because it will be close to the planet once that change occurs. The temperature of the sun will also increase tenfold from 18 million to 180 million degrees Fahrenheit. The increase in the sun’s size when it finally begins to change will be due to the heat increase causing expansion.
