An artist 2024 YR4 asteroids impression that could be as it approaches Earth in December 2032

NASA has renewed the risk of 2024 YR4 asteroids in 2032 from 2032 to 3.1, or a 1-1-32 The opportunity, yet not collisions of collisions yet.
The astronomers found that it was an asteroid In December to earth And since it has been the focus of world telescopes and space agencies. As the asteroids compile more data in the exact orbit, astronomers have had the opportunity to knock the ground with greater accuracy. The asteroid is believed to be between 40 and 90 meters wide and has the capacity to release the equivalent of 7.7 Megatonnes. It is enough to destroy a city.
According to the NASA, the options for collision in 2032 have been falling with options 1 and 83 since the first time was seen. Since 1-67 he gone to 1-in-53, until 1-in-43, 1-in-38 and now 1 and 32. The European Space Agency has somewhat different, Today the asteroid allows 2.81% to collide.
This continuous increase does not necessarily mean that the asteroid can actually hit the ground, and, however, can still be downloaded. “He has risen last week, doesn’t mean it will continue to do that,” he says Hugh Lewis University of Southampton, United Kingdom.
But we are running out of time to predict the risk of the asteroid. It is a specimen that 2024 Yr4 will fly behind the sun in April, bringing it from the point of view of most telescopes based on the ground. This limits how many astronomers can fix their predictions, Lewis says. “When he leaves us all the observations we can do now, it will help us improve the orbits and make better predictions. This will not necessarily describe it before April, but it was ultimately loses us.”
Given the asteroids, we can hardly get that we will get more information before re-entering 2028. However, astronomers could vary through past data, the trajectory would help the asteroid, which will improve theirs. This process is already being done by World Space Agencies, Lewis says.
Decisive information on the size and composition of weekly, James Webb Webb Space telescopes in the coming months, Lewis says. This will help us whether asteroids can do it through the atmosphere of the Earth or whether it may have a great explosion that can affect.
“This will help you determine what we need to do, because if the asteroid is a stone, it is very different from the proportion of iron metal asteroid,” says Lewis. An iron asteroid would be worse when the rocky asteroid can cause. “Mass is a huge difference in terms of energy and whether the atmosphere affected.”
