Asteroid 2024 YR4 could take earth in 7 years - measures and consequences
A recently discovered asteroid, known as 2024 yr4 Rel = "NOFOLLOW" TARGET = "_ Blank" href = "https://cneos.jpl.nasa.gov/details.html#?des=2024%20yr4" Target = "_ blank"> nasa and the European Space Agency a probability of 2.8% to 3.1%, the earth in 2032. Although the chances of an impact are low, astronomers carefully pursue the asteroids to collect more information - a process that could soon include the most powerful observatory that has ever been sent into space.
The properties of 2024 YR4
over 2024 YR4 is not much known so far, but the Asteroid is estimated at a width of 40 to 90 meters (131 to 295 feet), which is "comparable to the size of a large building", explained Dr. Paul Chodas, Manager of the Center for Near-Earth Object Studies (CNEOS) in the Jet Propulsion Laboratory from NASA in Pasadena, California.
In comparison, the "planet killer" sancid, which hit the earth 66 million years ago, and for the dying of the dinosaurs , around 10 kilometers (6.2 miles) and is known as the last large asteroid that hit our world. Asteroids that are considered a "planet killer" have a diameter of one kilometer or more and could have catastrophic effects on life.
The importance of observations
Smaller asteroids can, however, cause regional devastation if they are found on the collision course with the earth. Therefore, astronomers have to collect as much information as possible over 2024 yr4 as soon as possible. Collecting further data, for example to refine the asteroid trajectory, could reduce the likelihood of direct impact to zero. However, astronomers only have a limited time to observe the asteroid before he disappears from the field of vision in April. Therefore, plan to align the James-Webb world dream telescope to 2024 YR4 in order to be able to determine the size and orbit of the asteroid.
persecution of a potentially dangerous asteroid
The Asteroid Terrestrial-Impact Last Alert System (Atlas) in Rio Hurtado, Chile, discovered YR4 on December 27th. This telescope is one of the programs financed by NASA to discover close earth body, explained Davide Farnocchia, navigation engineer at the JPL and CNEOS, by email. Since then, the asteroid's size has only changed minimally, although several telescopes have been used for observation, since the asteroid can only be examined on the basis of the level of light reflection.
The James Webb telescope, which is to begin with observations from 2024 YR4 in early March, can measure the heat that the asteroid reflects and provide a much more precise size. Since the beginning of January, astronomers have also used the Magdalena Ridge Observatory in New Mexico as well as the Danish telescope and the very large telescope in Chile to pursue the asteroid, which is currently more than 48 million kilometers away from Earth.
risk assessment and impact consequences
The exact knowledge of the size of the asteroid can help astronomers estimate the risks if 2024 YR4 is determined as the future collision course with the earth. "If the asteroid is at the top of its estimate, the impact could cause damage within a radius of 50 kilometers (31 miles)," said Chodas.
In the past, asteroids of this size have hit the earth every few millennia. According to the
