Asteroids|Asteroid 2024 YR4 is now at the forefront of the threatening stone mountain monitoring list. The impact on the earth is now about 2.3 percent.
The abstract is made by artificial intelligence and checked by man.
Space Telescope James Webb will soon be investigating the size of the Asteroid 2024 YR4, which threatens the country, more closely.
Asteroid may hit the country in 2032 with a probability of about 2.3 %. Estimates are constantly changing.
According to NASA and the European Space Agency’s ESA, the asteroid diameter is 40-90 meters. It could destroy the city when it hits a bad place.
Webb describes the asteroid on the wavelength of the infrared twice for a few hours. With the help of the infrared, the size of its size is refined.
Citybig, could be destroyed if a large apartment -sized asteroid 2024 YR4 would hit the ground at Christmas 2032 and thus in the middle of the settlement.
In this way, astronomers who have been mapped by the threats of the asteroids in January-February. The risk of a hit is low, but still the biggest calculated for large asteroids.
Researchers following asteroids now want to find out the size of the big Kivivuori.
2024 YR4: N The size has not yet been fully clarified. Astronomers estimate that the asteroid has a diameter of 40-90 meters, the most accurate estimate is 60 meters. The asteroid could destroy the city when it hits a bad place.
The track calculations suggest that the asteroid 2024 YR44 has a probability of about 2.3 % to hit the ground, Tells a website live science. The probability of the impact has slightly increased in recent days.
If an asteroid struck the ground, its speed would be about 100 thousand kilometers per hour, the NASA unit following the asteroids will reduce the CNAOS.
The asteroid is still far from the globe on its track. With any terrestrial telescope, its size does not yet have an accurate picture.
The terrestrial telescopes record the sunlight that is reflected on the surface of the asteroid.
The evaluation by the reflection gives a limited picture of the size of the asteroid, says the European Space Agency ESA’s blog.
“Usually the brighter the asteroid, the bigger it is. However, this depends a lot on how the reflective asteroid surface is. ”
Space telescope James Webb Measure the asteroid differently.
First of all, it is one of the most accurate telescopes. In addition, it describes the asteroid with infrared wavelength. It’s more accurate.
In addition, it depicts an object in space, together with the so -called lagrange points. Thus, observations are not disturbed by the Earth’s atmosphere or clouds.
This will help webb to limit the real size of the asteroid.
Webbi Not designed to monitor asteroids. Therefore, it has not been used for it.
However, the threat of 2024 YR44 has now increased. Therefore, the Webb administration promised a full four hours to monitor the asteroid.
WebB will be applied to 2024 YR44 twice, March -May. Time for monitoring comes from the webb’s annual time storage. There have been free hours in the warehouse for surprising space.
Webb For the first time, observes the asteroid when it is near the sun at its brightest.
In May, webb will glance at the asteroid again as it moves further away from the sun.
The next time the asteroid to be blamed will be close to the country in 2028. Then it will overtake the globe safely, about eight million kilometers away.
The asteroid closest to the land – or straight towards – will not come until late December 2032.
“The city destroy” Asteroid was discovered by the US Space Administration in late December 2024 Nasa Department following asteroids.
The discovery has now risen to the top of the professional observation list.
“It is important that we refine the estimate of the size of the asteroid. The impact of about 40-meter asteroid on the Earth is very different from 90 meters,” ESA blog writes.
Asteroids threatening to the earth is measured by the so -called On the scale of the market. It has ten steps. The threat of YR4 is now on a scale of 3. In definition of scale 3, the following means: “The actual collision is very unlikely and does not require precautions.”
If the danger of the impact rises, two groups will be revived. One is set by Nasa, the other Esa.
Usually the calculations fall down as the asteroid is examined in more detail. So the risks are reduced, reassures the BBC in the news astronomer Robert Massey From the British Astronomical Society.
