A New, Brighter Kretuz Sun-Grazing Comet




A comet called C/2024 S has been discovered, this is a surface of the Sun of Kretuz, they are a very curious family of Comets, it is called that because they are the fragments of an ancient giant Comet and I am not exaggerating, it was a Comet giant that came too close to the Sun, in fact, the characteristics of these comets and all their fragments of this family of gradients is that they get too close to the Sun and many of them end up destroyed.


The largest ones survive, but most end up melted by the heat of the sun. Currently this new comet is located in the constellation Hydra and is easier to see from the southern hemisphere before dawn, from the northern hemisphere it is located very low on the horizon. In the southern hemisphere, the best time to see this comet will be in the days before perihelion, which will be on October 28, while in the northern hemisphere, the comet may be visible a few days after perihelion if it survives.


If it survives, in both cases, that is, in both the northern and southern hemispheres it could be seen with a brightness similar to that of Venus, so its brightness would be even more powerful than the Tsuchinshan-Atla, although This brightness of Los Cometas is somewhat variable, it could even surpass the Tsuchinshan-Atla brightness, so it could also steal the title of Comet of the century, this does not mean that the new Comet is very big, here what matters is that It will pass very very close to the sun, that is what the Kretuz sun rays do.



Souce Comet Tsuchinshan-Atlas


Comet Tsuchinshan-Atla had its closest approach to the sun on September 27 at 58 million kilometers, that is more or less the distance at which Mercury orbits, but this new comet will have its closest approach to the sun on October 28 at only 1, 2 million kilometers, that is literally touching the solar atmosphere and of course the closer to the sun the more heat and the more ice vaporizing like crazy and that is why it can shine much brighter.


These astronomical phenomena put us in perspective of the dangers of the cosmos, this fragment, this comet that will surely be visible with an intensity similar to that of Venus, is a fragment of a giant comet that is estimated to have been at least 100 km in diameter and which broke when approaching the sun around the year 371 BC, as recorded by the ancient Greeks, and which then fragmented even more in its subsequent steps near the sun.


One of the most important breakups must have occurred in the Middle Ages and here there are records of a great comet that broke up in the year 116. All this is known because they followed the same trajectory and in this way it has been deduced that they are all from the same family, so that you have an idea of ​​the volume of fragments and their number, since the launch of the SOHO satellite, which is one of those that observe the sun that was launched in 1995, this satellite has been seen falling into the sun or passing very More than 4,000 comets were found near it and it is believed that 25% of them belonged to this family.



Souce Comet ikeya seki in 1965


Most would be less than 200 meters in diameter, but there are also fragments of several kilometers in diameter that have been seen in the skies in a spectacular way, some are enormous that can exceed 10 or 20 km in diameter, it is difficult to know the real diameter. of the nucleus of a comet because when we see it it is already surrounded by a large layer of gases and due to the vaporization of the ice, but the intensity with which the great Comet of 1843 shone, for example, was impressive. which was a cosmic spectacle.


The tail was extremely long, it stretched over more than 50% of the sky. It has been calculated that the tail of that comet measured 480 million km. The most recent large comet of these pieces of that ancestral comet was Comet Ikeya. Seki C/1965 S1 which was also one of the brightest comets of the last 1000 years.


These two comets, both the one from 1843 and the one from 1965, also ended up breaking up because they passed very close to the sun, so when we see them again we will see their fragments pass close to the sun, they will no longer be so big anyway, think about the following , all these fragments, that giant comet, if they get so close to the sun it is because they cross the Earth's orbit, so a giant comet of more than 100 km crossing the Earth's orbit that is something terrifying and yet it happened 23 centuries ago which in cosmic time is very recently.


How many giant comets can there be out there, when will the next one come?
