First, astronomical angle.
From an astronomical point of view, a star refers to a celestial body in the universe that does not emit light by itself and rotates around other celestial bodies. These celestial bodies usually include stars, planets, satellites and so on. Among them, stars are celestial bodies that can emit light by themselves, while planets and satellites cannot emit light, but can only rotate around celestial bodies such as stars or other planets. These celestial bodies form a huge galaxy in the universe, and each galaxy has hundreds of millions of stars.
Second, the cultural perspective

Therefore, many literary and artistic works take the stars as the theme, such as the famous fairy tale The Little Prince, which takes the stars as the background to express people's yearning and pursuit of beautiful things.
Third, the scientific point of view.
From a scientific point of view, stars involve many fields such as physics and astronomy. For the study of stars, scientists not only explored their basic characteristics such as composition, structure and properties, but also inferred the origin and evolution of the universe by observing the changes in brightness and color of stars.
In addition, through the study of stars, people have discovered many new physical phenomena and laws, such as black holes and supernova explosions. These studies not only help people better understand the nature and laws of the universe, but also provide important reference for scientific research.
To sum up, star is a multi-angle concept. From the perspectives of astronomy, culture and science, stars have different meanings and values. Whether as a natural phenomenon in the universe or as a part of human culture, stars play an indispensable role. For people, by understanding the stories and scientific principles behind the stars, we can not only broaden our horizons, but also stimulate our desire to explore the universe and life, and better feel the mysteries of life and the universe.
