Final Answer:
Our Sun is different from Earth. How so? Our Sun is a giant ball of burning gas! The Sun is a star. Look down. Are your feet on fire? Hopefully not. Earth is a planet, not a star, and Earth is not burning up. (Sure, we have forest fires and volcanoes but that is not the same as the whole world being on fire all the time.) Our Sun is not the only star. When you look at the night sky, you see only some of the billions of stars in our universe. Lots of stars are bigger and brighter and hotter than our Sun. There are also many that are smaller and dimmer and cooler. Our Sun is a medium-sized star. So why does our Sun look like the biggest and brightest one? One simple reason: it’s the closest to us. If you traveled by rocket to the Sun, it would take about 7 months. If you traveled in that same rocket to Proxima Centauri, the next closest star after our Sun, it would take 157,000 years! Because the Sun is so close, it appears much MUCH bigger and brighter to Earthlings than any other star.
