NASA has recently issued a new warning about the asteroid named YR-4, which is currently around 500,000 miles away from Earth and is moving toward our planet. According to NASA’s latest observations, this asteroid may either pass close to Earth or impact it in the year 2032. The warning highlights several major cities, including Mumbai, Kolkata, and Dhaka, as being at risk if the asteroid collides with Earth.
Increasing Probability of Impact
Initially, NASA estimated the probability of YR-4 hitting Earth at an extremely low percentage, around 0.5% to 0.7%. However, with more recent calculations, the probability increased to 1.3%, then to 1.8%, and now it has reached 3.1%. This sudden rise in probability has made space agencies more alert and proactive in addressing the potential threat.
Although this asteroid is not large enough to destroy the entire planet, it is categorized as a “city killer.” If it impacts a densely populated area like Mumbai or Kolkata, the destruction could be catastrophic, causing massive loss of life and infrastructure damage.
NASA and China’s Response
Given the increasing probability of impact, NASA has started exploring possible solutions to mitigate the threat. One NASA official emphasized that dealing with this situation at the last moment is not an option. They are considering ways to either destroy or deflect the asteroid before it reaches Earth.
Meanwhile, China is also preparing for planetary defense. The country has already begun developing a planetary defense force to counter potential asteroid threats. With both the United States and China actively monitoring and planning for asteroid impacts, international cooperation might be crucial in tackling such threats effectively.
Why Is This Asteroid Different?
Throughout history, numerous asteroids have approached Earth, but most have had an impact probability below 1%. YR-4 is an exception. This is the first time in recent history that an asteroid larger than 30 meters has had a probability exceeding 1%. This makes it a rare event and a cause for concern among scientists.
The probability of impact may still fluctuate as more data becomes available. Scientists are continuously tracking YR-4’s trajectory, and minor deviations could determine whether it will hit Earth or pass by safely.
NASA’s Latest Observations
NASA’s latest statement indicates that new observations have slightly reduced the impact probability to 1.5%, but it is still under evaluation. The European Space Agency (ESA) maintains a 3% probability, indicating a significant level of uncertainty in the asteroid’s trajectory.
According to NASA’s models, YR-4 will pass extremely close to Earth. If even a small deviation occurs in its path, the asteroid could impact Earth. Scientists are expected to refine these calculations further in the coming months.
What Happens If It Hits Earth?
If YR-4 impacts a major city like Mumbai or Kolkata, the effects would be devastating. The asteroid is estimated to be between 40 to 90 meters in diameter and is traveling at 16,649 mph (26,800 km/h). Such an impact could cause an explosion with the force of a nuclear bomb, flattening buildings and causing mass casualties. It could also generate shockwaves, fires, and secondary damage over a vast area.
Besides direct impact threats, there are concerns that the asteroid could damage satellites, the International Space Station, or other space infrastructure.
Should India Join NASA’s Efforts?
Given that Mumbai and Kolkata are identified as potential impact zones, it would be in India’s best interest to actively participate in planetary defense initiatives. India could collaborate with NASA and other space agencies to develop early warning systems and asteroid deflection technologies.
China is already working on its planetary defense initiatives, while the U.S. has been researching asteroid impact prevention strategies for years. India’s involvement in these efforts could enhance its space research capabilities and ensure its own preparedness in case of future threats.
What Next?
NASA and other space agencies will continue monitoring YR-4 closely. It is possible that future observations will refine the impact probability further, either reducing or increasing the risk.
In the coming months, more data and research papers will be published, and the situation will become clearer. If necessary, asteroid deflection strategies, such as kinetic impactors or nuclear deflection, could be considered to prevent a direct collision.
Final Thoughts
While there is no immediate cause for panic, the increasing probability of an asteroid impact near major cities like Mumbai and Kolkata is a serious concern. NASA and other space agencies are closely monitoring the situation and preparing for potential mitigation strategies. India must also consider joining international efforts to ensure that it is not caught unprepared in the event of an asteroid impact.
For now, all eyes are on NASA’s upcoming updates regarding YR-4, which will determine whether this asteroid will safely pass Earth or pose a direct threat in 2032.
