One is a person who imagines the vast universe, and the other is a person who observes the infinite universe. These two things named after asteroids have sparked a discussion in the small circle of astronomy lovers and science fiction lovers. There are countless asteroids in the universe. Why do people pay attention to the acquisition of asteroid names?
There are many types of asteroid names, including classical myths, outstanding figures, place names, units and so on. In China, there are more than 100 asteroids named after China's outstanding figures, China's place names and famous units. 202 1, 165438+29 In October, asteroid 23692 was named Nantah Astronomical Student Star, which is a unit name.

It is almost impossible for ordinary people to get the name of an asteroid. Because of the seriousness, permanence and invariance of asteroid naming, the names are generally given by units or individuals who have made great contributions to economy, society and astronomy.

The International Astronomical Union also made a special statement: "The Union is an international scientific organization, and it will never participate in any commercial sale of the names of stars or land on the surface of the planet. If you want to buy it after reading our explanation, those who took your money will be very happy. "
