On the night of August 19, a brilliant meteor fireball made a spectacular entrance across the sky in western Japan, dramatically illuminating the darkened landscape of cities and towns. This celestial event radiated light as the fiery object blazed a path towards the sea, with experts estimating its size ranged from a few centimeters to several meters in diameter.
This extraordinary display reminded observers of Earth's position within the vast universe, a stunning spectacle that also raises concerns in the case of a direct urban impact. Each year, the Earth experiences over 5,000 tons of cosmic debris, most of which safely incinerates in the atmosphere, while a select few survive to reach the surface.
Currently, a considerable focus is directed toward asteroid 2024 YR4, a near-Earth object deemed comparable in size to a 15-story building. Should it collide with Earth, the energy released would be immense, potentially causing destruction over a wide area. Initial assessments highlighted a small risk of a collision, but subsequent observations have significantly diminished this concern, bringing the risk nearly to zero. However, scientists have not overlooked the possibility that this asteroid may still impact the Moon.
Mathematician Norio Konno has provided context on probabilities regarding such cosmic events. For instance, winning the lottery carries an incredibly low chance of one in 10 million, while experiencing a house fire is more common, at one in 1,426 per year. In contrast, the likelihood of dying from a massive meteor impact in one's lifetime is about one in 32,400—an alarming figure that, although not a nightly concern, emphasizes the reality of such risks.
An old tale from China narrates the anxieties of a man who fretted incessantly about celestial bodies falling from the sky, coining the term "kiyu," which signifies anxiety steeped in imagination rather than probability. While this notion of cosmic worry may have seemed far-fetched, the consideration of a potential meteor strike on a city is becoming increasingly relevant in today's world.
In the popular daily column Vox Populi, Vox Dei, readers are encouraged to explore various topics, including cultural and social trends in contemporary Japan, shedding light on the narratives that shape the nation's complexities.

“Cosmic anxiety”? What’s next? Worrying about alien invasions? Grow up.

This is just scare tactics! The chances of a meteor hitting us are so low — focus on what really matters.
