Definition
天体 primarily means 'celestial body' — any natural object in outer space such as stars, planets, and moons. In astronomy, it also refers to the 'celestial sphere', the imaginary sphere around Earth on which celestial objects appear to lie. Note that in informal or Taiwanese usage, 天体 can also mean 'nude body' (a homophone-based pun), but this sense is secondary and should be used with care.
