It is located at the edge of the solar system, the area that encloses the solar system, where there is a lot of cold rubble, comets, asteroids, and a thick Kuiper strip that wraps the solar system.

It is the region on the outer side of Neptune's orbit, where there are many small planets. This is the famous asteroid belt, where the former Pluto was discovered.

The Kuiper Zone is the edge of the solar system where there is a large amount of dense celestial material, which is likely to be some meteorite fragments, ice and other materials that were born when the solar system was formed, which may be the boundary of the solar system.

First of all, the formation of any new star requires a dense cloud of nebula gas, through the continuous movement of the nebula and the stellar gravity in the swaddling center, the nebula gradually concentrates itself, forming the central main star, and then forming a protoplanetary disk, after billions of years of evolution constitutes this stable structure similar to today's solar system: the main star enters a vigorous life cycle, the energy released remains stable, and the orbiting planetary systems orbit around the main star according to a relatively stable orbit, constituting a stable astrolabe.
For example, NASA even defines it nearly two light-years away, almost half of the distance we have to Proxima Centauri (and the Kuiper Belt belongs to the periphery of this primitive astrolabe (about 4.5 billion kilometers away from the Sun), which is equivalent to the junction between the main planetary region of the solar system and the outer residual nebula (Oort Cloud), which is simply a nucleus to the entire atom compared to the scale of the Oort Cloud.
Here, the Sun's gravity interacts with the influence of the giant planets Saturn, Jupiter, Uranus, and Neptune. Different planets have different orbital periods, so for the Kuiper Belt, the gravitational pull of different periods, such as Saturn revolving around the Sun for one rotation and Jupiter for two weeks, makes the Kuiper Belt constantly affected by this periodic gravitational pull (resonance). Its effect makes it very unlikely that a giant planet will spawn in certain parts of the solar system.
Over time, the Kuiper Belt has formed a region of microstars and fragments of the original astrolabe, and Pluto is also located in this region.
The Kuiper Belt is still very little understood, and astronomers have thought it was empty and the end of the solar system. However, with the development of astronomical observation technology and the improvement of human computing power, the concept of the Kuiper Belt and the Oort Cloud has gradually taken shape and been confirmed. The mature Kuiper Belt theory first began in the 50s of the last century, and is a set of astronomical research systems proposed by the Irish scientist Edgeworth, and studied and deepened by the Dutch-American scientist Kuiper.
However, the observation conditions at that time were still not enough to directly find such distant practical evidence, and the first Kuiper Belt object was discovered in 1992. At present, the ability of human beings to explore deep space has been greatly enhanced, and more small celestial bodies have been discovered here. According to current estimates, astronomers even believe that the discovered Kuiper Belt objects may only be the tip of a small Xiaoice mountain, where the number of objects is likely to exceed 1 billion, and the number of asteroids with a diameter of more than 100 kilometers may be as high as 35,000, which is indeed a huge system.

Betel nut seems to be a specialty of Hunan, I have eaten it, and it is very cool in my throat.
Love is a very abstract thing, a feeling, a taste, a thought, a feeling, a satisfaction, a new hope, everything, affecting the whole body and mind and joyful emotions. It is when you think of a person, you will pray for him to be happy and safe, you will want to accompany him forever, in the lonely night, thoughts come like a tide, holding a book in your hand but you can't read it, thinking about him in your heart, whether you think about yourself as much as yourself.
One of the easiest ways is to wrap things in plastic wrap when you put them in the fridge, so that the smells are not easy to smell each other, and there is no strange smell in the fridge.
