If the researchers display as much serenity, it is because they have an excellent detection network today. Automated telescopes, international databases, real -time orbital calculations: most objects that deserve our surveillance are tired. Astronomers are more worried when it comes to an asteroid that they could not detect in time.
The best contemporary example is certainly the explosion of Tcheliabinsk, which occurred on February 15, 2013, which still remains a case of school in astronomy. That day, an asteroid about 20 meters in diameter entered the atmosphere without having been spotted upstream. He exploded about twenty kilometers above sea level above the Urals, releasing an estimated energy at 500 kilotons of TNT, approximately 30 times the power of the Hiroshima bomb. The shock wave blowed thousands of windows and damaged many buildings, making more than 1,500 injured, mainly due to the glass bursts caused by the explosion.
Since then, space agencies have considerably intensified their watch. More than 30,000 objects close to the Earth are now identified, a figure that increases each week. By 2029, a colossus baptized Apophis (approximately 467 meters wide and 167 meters high) will make a passage very close to our planet. At the time of his discovery in 2004, there was an impact in 2036, but which will never take place, simply because the calculations of his trajectory were revised.
So we have no reason to be afraid of OW 2025; He will pass without even not noticing and continuing his journey in the depths of the cosmos. Others after him will follow, in general indifference, but still closely followed by international surveillance programs. For those who were perhaps hoping to observe the passage of OW 2025, unfortunately, you will have to change it; It will only be a tiny light task in the sky, even if you are armed with an excellent telescope.
