Frequently asked questions (FAQ)
What is the size of the asteroid?
2024 years is estimated at around 130 to 300 feet in diameter (40 to 90 meters).
Asteroids 2024 years old will he have an impact on earth?
Currently, the asteroid 2024 YR4 is very small to have an impact on the earth on December 22, 2032. As more observations are collected and the data is added to orbit calculations, it This probability is likely to fall to zero. The probability of impact for this asteroid will continue to be reassessed while astronomers continue to follow it. In April 2025, the object will be so far that it will become too low to be detected by earth -based telescopes. Other updates will not be possible before 2028, when 2024 years once again approaches earth and becomes brilliant enough to be detected. The last probability of impact is available on automation Sentinel Page to the center for studies of objects close to the Terre de la NASA at the Jet Propulsion Laboratory.
How much damage does an asteroid of this size cause if it should have an impact on the earth?
The damage caused by an impacting asteroid depend on the exact size and composition of the asteroid. The exact size of 2024 years is still uncertain, but a scenario is a probable scenario for its size range. If asteroids entered the atmosphere on the ocean, the models indicate that the aerodynamic objects of this size would probably not cause significant tsunami, either from the middle of the ocean, or in the closer shore.
If the asteroid has entered the atmosphere in a populated region, an update on the smaller side of the size range, around 130 to 200 feet (40 to 60 meters) could break the windows or cause Minor structural damage in a city. An asteroid of about 300 feet (90 meters), which is much less likely, could cause more serious damage, potentially collapse residential structures through a city and break the windows in larger regions.
How does NASA determine the probability of the impact of asteroids?
The observations program close to NASA finances observatories to search for unseated asteroids and follow the potentially dangerous asteroids existing. Using observation data, NASA teams calculate and refine the orbits of objects close to the Earth using computer models. Once the orbit of an asteroid is calculated, these same computer models at the center for studies of objects close to the earth can project how the asteroid could approach the earth over the years and decades to come .
Why does the probability of impact change so frequently? Where can I see the last probability of impact?
This is the scientific process! While NASA and other people involved in the international asteroid alert network brings together more asteroid observations 2024 years, the future asteroid trajectory can be better understood. This is an opportunity to observe the science of planetary defense in action. As new monitoring data are available and new probability assessments are carried out, these results will be published on the Sentinel Risk list page.
Is it possible to divert the asteroid 2024 years? Could we use a spaceship similar to Dart?
A spatial vessel of the kinetic impactor such as the mission of the NASA double asteroid redirection test (DART) is a technique of deviation from asteroids that could be used to approach a potentially dangerous asteroid in the future. Each asteroid is unique and the deviation would depend on the size of the asteroid, the physical properties, the orbit and the discovery warning time. For 2024 years, we are still in the information collection stadium. The probability of an impact on the earth is still very low and will probably decrease as we gain more observations, it is therefore premature to speculate on potential deviation techniques.
Preview
The asteroid 2024 YR4 is an asteroid close to the earth, which means that it is an asteroid in an orbit which brings it to the soil region of the solar system. 2024 years old is estimated at around 130 to 300 feet (40 to 90 meters) wide and has a very small chance of impact on earth on December 22, 2032.
This object is particularly interesting for planetary defense For two reasons: 1) It is large enough to cause localized damage in the unlikely case that it should have an impact on the earth, and 2) while 2024 YR4 has a very low chance of impact on the earth in 2032, he exceeded the 1% impact threshold to justify an official notification of the object to others American government agencies involved in planetary defense as well as for the Spatial mission planning advisory group and at United Nations External Space Affairs Office speak International asteroid alert networkNotification charter.
As more observations of the asteroid orbit are obtained, its probability of impact will become better known. It is possible that 2024 YR4 is excluded as a risk of impact, as happened with many other objects that have appeared before on NASA JPL List of asteroid risks. It is also possible that its probability of impact continues to increase. The latest data will continue to be available via automated NASA Sentry page. Updates will also continue to be published on the planetary defense of NASA blog.
Discovery
2024 YR4 was first reported to Minor planet – The international compensation house for small positions of position on the body – by the financing of NASA Asteroid terrestrial impact alert system (Atlas) in Chile on January 27, 2025. Atlas includes several telescopes around the world and is managed by the Astronomy Institute of the University of Hawaii.
