Ryuusei, meaning "shooting star" in Japanese, refers to a meteor that streaks across the night sky. These celestial events occur when small particles from space enter the Earth's atmosphere and burn up due to friction, creating a bright trail of light. Ryuusei are often associated with wishes, as many cultures believe that seeing one brings good luck. In Japanese culture, Ryuusei is also linked to various myths and folklore. For instance, the Tanabata festival celebrates the meeting of two stars, Orihime and Hikoboshi, and is often accompanied by wishes made upon seeing a shooting star. This connection highlights the significance of Ryuusei in both astronomy and cultural traditions.
