Astral objects are celestial bodies that exist in the night sky, such as STARS, planets, comets, and asteroids. The term 'astral objects' is often used to refer to STARS, which are the most visible of these objects. STARS are luminous spheres of gas that emit light and heat due to nuclear fusion reactions in their cores. They come in a variety of sizes, colors, and temperatures, and can be seen from Earth with the naked eye.
