Celestial bodies are the general name of all kinds of stars in the universe. The celestial bodies in the solar system include the sun, planets, satellites, comets, meteors and interplanetary tiny celestial bodies. Celestial bodies in the Milky Way include stars, clusters, nebulae and interstellar matter. Extragalactic galaxies are celestial bodies as big as the Milky Way. There are also infrared source, radio source, X-ray source and γ-ray source discovered by the latest observation methods in recent years. All of the above belong to natural celestial bodies. Satellites, rockets, spaceships, space probes and space laboratories are all artificial celestial bodies.
The fate in the sense of human behavior should be understood as an act that modern people advocate returning to nature, returning to simplicity, and advocating harmonious coexistence between man and nature.
There are also many active celestial clubs on the Internet, so you might as well discuss them.
