When its identity was confirmed, many scientists expressed concern because this huge comet was approaching the solar system. If it collides with any celestial body near the earth in the solar system, it will undoubtedly be a huge disaster.
Unnecessarily worried that this comet was later named C/20 14 UN27 1 by astronomers who observed it. By observing its trajectory and after careful calculation, scientists analyzed that this comet will not bring disaster to the earth, because its trajectory will not intersect with the sun and the earth.
However, this comet is also a great discovery in astronomy-its huge size makes it the largest comet ever observed.
And when Comet C/20 14 UN27 1 comes to the solar system, it will be very close to the earth, so relevant scholars can better observe this "alien guest" and bring new scientific research results to the study of the primitive object of Oort Cloud. Moreover, through observation, we can trace back to the source and uncover the mystery of the birth of the solar system.
Gary Bernstein of the University of Pennsylvania, the discoverer of the giant comet C/20 14 UN27 1, was extremely excited. When he and his staff observed the comet, they realized that they might have found the largest comet ever, which was bigger than all the comets that could be fully studied by the literary world the day before yesterday, and they had observed it before it entered the solar system.
This is a very important discovery, because at present, a series of changes caused by temperature rise when comets approach the solar system are rarely completely observed. Relevant research teams show that this comet has not been to the solar system for more than three million years.
The mystery outside the solar system and the celestial bodies inside the solar system have always been the most concerned by the astronomical community. For astronomers, outside the solar system is a distant and mysterious place. Because the outer solar system is too far and too dark for us and the observable celestial bodies are very small, it is very difficult and challenging to explore any celestial bodies outside the solar system.
At present, astronomers gradually understand the structure of the outer space of the solar system through research. Through repeated observation and patchwork, they came to the conclusion that the Kuiper Belt is composed of small ice bodies, and further away is the Oort Cloud where the giant comet is located. These are just some general observations, and further details need to be explored.
Astronomers found in the process of observing comets that we can gradually expand the depth, breadth and accuracy of the exploration of celestial bodies outside the solar system, which will help us understand other celestial bodies outside the solar system and uncover their mysteries.
The orbits of these celestial bodies are about 30 astronomical units from the sun near Neptune. At the beginning of 20021,a foreign astronomer said that they found 46 1 unknown celestial bodies outside the solar system through the detected data.
The astronomer who discovered C/20 14 UN27 1 said, "This' brand-new' comet was not found to be less than 18 astronomical units away from the sun after it entered the Oort Cloud."
"In addition, this comet is likely to be the first and most primitive comet we have observed. We discovered it when it was still outside the solar system and never detected it in Neptune's orbit before. "
When this giant comet was discovered, it was about 29 astronomical units away from the sun. As time goes by, the year 203 1 will be the closest year to the sun, and its distance from the sun will gradually get closer, even reaching the distance of eleven astronomical units, while the distance of Saturn's orbit is about ten astronomical units.
With a diameter of about 155 km (96 miles), this giant comet is absolutely huge in the comet world. However, despite its huge size, when it is closest to the sun, we can't observe the trajectory of the comet with the naked eye.
Although observation is very difficult, scientists have not given up their research on giant comets. They explore the celestial bodies in the outer solar system through telescopes, hoping to find more data about giant comets and other celestial bodies, so as to understand the early form of the solar system.
Because there will be ice rocks on the edge of celestial bodies in the outer solar system, through research, the formation time of this substance was about 4.5 billion years ago, and it has not changed much until today. Therefore, scientists speculate that the ice rock volatiles in giant comets should have information evidence of the formation of the early solar system.
At present, astronomers have observed that this giant comet has signs of coma, that is, the comet atmosphere produced when the comet approaches the sun. In this process, with the increase of heat, the ice rock on the surface of the comet sublimates, forming a coma and gradually evolving into a comet tail. Spectral analysis of these signs will bring us more information about giant comets.
