Riddle: I come out every night to do the night shift. Sometimes I look fat, and sometimes I look thin. I can't light up by myself, yet I shine very brightly in the dark. Every day I obediently circle around Mother Earth, and the tides at the beach rise and fall all because of my pull. Guess the space object! Little Panda claps and gives you a hint: When I am full, I look like a round silver plate; when I become a crescent, I look like a golden banana. Ancient people used me to keep the lunar calendar, and you can see me every night when you pull open your curtains. Quick, guess who I am!
