The Dhaka Times Desk This is the first time in the history of Earth's civilization that a trace of a cosmic object has been found. Which is not a cosmic rock. Again, this is not a comet. However, these two together have a similar appearance - like the horseman of Greek mythology!
Scientists named it 'P/2019 LD-2'. This dim-looking cosmic object was first spotted by the Atlas telescope perched high on a mountain in the Hawaiian Islands. Noticed in May this year.
They are so bounded that they have no fixed orbit. They may again be orbiting in one of the orbits. And right after that he is seen hitting the puck - in another orbit.
Much like the horseman of Greek mythology! Neither man nor horse. Like a fictional creature 'Centaur'. Greek mythology says that these horsemen were not only very good archers, but also well versed in astrology and astronomy. Another incarnation of Vishnu in Hindu mythology is 'Haygriva'. Whose head is like a horse. The rest of the body is the four-armed Vishnu.
A similar legend of Greek and Hindu mythology has been seen in space this time. The paper on its discovery came online on August 10.
Ashok Sen, Professor of Astronomy at Assam University in India, says, 'No one has been able to observe such an event in the history of civilization, at least until now. Here is an asteroid slowly becoming a comet. Because of this, it has been possible to visualize for the first time how comets are born. Which is not known to have ever been seen before. So it can be said that this is a breakthrough event.'
Comets usually come from two regions of the solar system. It is a- 'Kuiper Belt'. The other is 'Ort Cloud'. Both of these are ice kingdoms. If the Kuiper belt after Neptune is called an ice empire, then the Oort cloud at the very end of the solar system is actually an ice empire. Comets usually have a lot of ice on their heads. As they come closer to orbiting the Sun, the sun's heat melts the comet's head ice to form its tail. It is called the comet's tail. A comet usually has two tails. One is opposite to the other.
Comets from the Kuiper Belt that come too close to Earth while orbiting the Sun usually return in much less than 100 years. Comets that come from the farthest Oort cloud take 100 to 200 years to return.
Last July, a comet was seen all over the world, including India, which returned after about 7 thousand years. That too came from his cloud.
Both Prof. Sunand and Ashok said that this dwarf-looking cosmic object will fully become a comet after at least another 43 years.
In Sunand's words, 'Last year, a group of researchers from the American 'Ceti Institute' showed that there is a place in space after Jupiter, which is called 'Gateway'. The comet's nest near there.'
Ashoka and Sunanda also reported that the calculations showed that this dim-looking cosmic object has also changed its orbit many times in the last two hundred years. In 1850 it was very close to Saturn. It approached Jupiter only three years ago. In 2017. It will become a full comet and start heading toward the Sun at least 43 years from today.
