Riddle: Once daytime arrives, I hang high up in the blue sky and clock in on time, and as soon as night falls, I quietly sneak off work. I never take a single day off all year round, yet I never need anyone to pay me a salary. My favorite thing to do every day is to send bright light and warmth to Mother Earth, and everyone has to wear a sun hat when they see me in the summer. Guess the space object! Little Panda claps to give you a hint: It is the super giant star closest to our Earth. Even light, traveling incredibly fast, takes only eight minutes to rush from it to Earth, and plants on the ground rely fully on it to grow. But children must never, ever stare directly at it with your little eyes. Give it a quick guess!
