Astronomers have raced 2024 YR4 asteroid observation

World Space Agencies have reduced options Asteroid 2024 Yr4 Earth’s influence below 1%, which strongly suggests that potentially destructive collisions will be avoided. However, the asteroid will probably pass very close to our planet, giving astronomers to approach an asteroid.
“We don’t expect the probability of influencing an impact of more than 1% of the nearby approach to the ground in 2032,” says Richard Moissl European Space Agency (ESA). “Probably more development is the decline in probability, it is likely 0.”
About alarms Asteroid 2024 Yr4 Last year they rose in December for the first time, when it could be in a Collision course in 2032. It seems to be 40 and 90 meters wide and should hit the city that could cause a deadly explosion. In the next few weeks, the telescopes and space agencies closely played his career, looking at the future path with greater accuracy. It was the most influential influence on February 17, with a chance of 1 and 32, but in the following days, this fell from 1 to 67, or a risk of 1.5 percent.
On February 20, new observations led to a sharp decline in this risk, with the behavior of 0.27, or 1-360, and a 0.16%. These ratings are placed on a scale of 10-point 10 points to evaluate the risk posed by such objects. This score is down from 3, means that it is one of the many minority asteroids that are located every 2024 YR4 year, but ultimately lost the earth.
This is good news, he says Gareth Collins Imperial College in London, but the asteroid will still be useful for the defense systems for our planet and scientific purposes. “It’s still something that will still be approached. If it was as big as the risk of knocking, he must be very close to us,” he said.
Nasa, ESAs and spaters and space companies were sketching the possible deviation schemes, says Niklas Voigt Ohb, German space company. Voigt and his team started thinking about a mission to divert 2024 Yr4, and the new risk does not change that, he says. “The risk has decreased, but in the time we continue with the work on the subject.”
The close view can have a good opportunity to divert the asteroids, they say, this is the mission of this, which is NASA’s Dart. We could build a satellite to send to 2024 YR4, similar to the Satellite of ESA’S RAMSES, due to the travels to observe asteroid, Apophis, 2029 must pass near the ground.
2024 The final decision to be done in YR4 will not be achieved until the scheduled observations of March using the James Webb Space telescope. Also collects the trajectory data, which will better evaluate the size and composition of the asteroid. This information will be fueled by the United Nations Protected Space Missions to the Planning Advisory Group, which will decide the best action at the end of April. “Exercises to find decision-making points are very useful for having time to do something in advance,” Collins says. “Completely, these committees will be meeting yet, but they will probably have less stress.”
Although the influence of the Earth has affected, 2024 Yr4 risk Moon They rose to 1.2 percent, more than 0.3 percent. There is more that this number rises, “says Moissl.” The specific effects of influencing the moon are still evaluating from an object of that size. “
The answer to this object also has been a useful rehearsal for other agricultural asteroids, Collins says. “We want to avoid before, the situation in the future Wolf, where the public thinks that the public is so unfamiliar with this threat,” it never happens. “
