S. asteroid 2024 yr4And discovered at the end of last year, raised new concerns about the possibility of a collision with the Earth in 2032. However, the risk of reaching our planet has decreased significantly, and it is no longer a threat. However, 2024 YR4 is still accompanied and studied. now, The new notes made by the James Web telescope for space to get more accurate information about their size, as well as pictures.
ESA, one of the space agencies participating in the James Web project, explains this The photos were taken on March 8 to the camera near the Infred (NIRCAM) and the mid -Infred tool (Miri). The data collected by NIRCAM shows the light on which the asteroid and notes that were made with Miri show the thermal radiation emitted.
The data collected by the telescope is used by scientists to study thermal properties from the asteroidIncluding the speed that it rises or cools and what is its temperature in the current distance of the sun.
Accordingly This isNotes indicate this 2024 YR4 does not participate in the same features that were observed in other largest asteroids. Despite the need for more research, the thermal properties of this asteroid are the result of a mix between the high speed of rotation and the presence of rocks, similar to the wrist or larger on its surface.
The telescope notes also help the asteroid’s dimension more precisely. The new data indicates that it should measure between 53 to 67 meters. By comparison, previous estimates indicated a diameter of up to 90 meters.
To date, Asteroid 2024 YR4 is the smallest object captured by James WebbLike one of the smallest spatial objects whose dimensions are measured directly, ESA enhances.
In February, NASA reached the conclusion that the asteroid It did not pose a danger to the ground. “The possibility of the 2024 YR4 asteroid effect decreased to 0.004 %. It is expected to be safely through Earth in 2032.”The agency said at that time.
On the other hand, the new data collected by James Webb, as well as information from earthly telescopes, is allowed to review another probability rate. If at the end of February, the asteroid who collided with the moon was likely to be 1.7 %, and now this The value rises to 3.8 %.

Despite the rise, NASA recalls that the possibility of no collision is still the most quieter (96.2 %). But if this happens, the effect will not change the orbit of the moon, as the agency indicates.
As the asteroid follows its way, the notes become more complicated. However, NASA expects to be able to notice it again, with both earthly telescopes and James Web in late April or early May. In 2028, the asteroid 2024 YR4 will pass near the ground, which will allow more data to collect orbit and properties.
