Definition
恒星 (héng xīng) is the scientific/astronomical term for a 'star' that generates its own light, like the Sun. Unlike the everyday 星星 (xīng xing, any twinkling point in the night sky), 恒星 specifically refers to a light-producing celestial body, while 星球 (xīng qiú) is the broader 'celestial body' that includes planets and moons.
noun
