"해와 달" translates to "the sun and the moon" in English. The sun is a star at the center of our solar system, providing light and warmth to the Earth. It plays a crucial role in sustaining life by enabling photosynthesis in plants and regulating the climate. The moon is Earth's only natural satellite, orbiting our planet and reflecting sunlight. It influences ocean tides and has been a source of inspiration in various cultures and mythologies. Together, the sun and moon create a cycle of day and night, shaping our daily lives and natural rhythms.
