How to Understand
恒星
恒星 (héng xīng) refers to a star, specifically a celestial body that emits light and heat through nuclear fusion. Unlike planets or other astronomical objects, stars are massive and self-luminous, making them central to the structure of galaxies.
The character 恒 (héng) means 'constant' or 'eternal,' and 星 (xīng) means 'star.' Together, they imply a star that is constant or eternal in the sky, reflecting ancient observations of stars as unchanging points of light in the night sky.
In modern usage, 恒星 is commonly used in astronomy and general contexts to refer to any star. It is also sometimes used metaphorically to describe something stable or enduring, though its primary meaning remains astronomical.
