Topline : An asteroid that could have destroyed an entire city that passed Earth earlier this week – and scientists did not notice it until there was only one more A day's drive from Earth was passing by.

  • The rock called Asteroid 2019 OK was 57 to 130 meters wide and not large enough to trigger the extinction of the dinosaurs, a city killer "that could have leveled an entire city.
  • Nearby, he flew 73,000 kilometers from Earth to put it in perspective: That's less than a fifth of the distance to the Moon after The Washington Post .
  • The asteroid surprising te scientists with his astronomy teams in Brazil and the US discovered the asteroid only on Wednesday, the day before he flew near the earth.

Asteroid 2019 OK was able to evade observers because it is relatively small compared to other large asteroids. And it traveled fast at about 54,000 miles per hour. Moreover, it only reflects enough light to be picked up by a telescope when it is a few days away from Earth, and even then astronomers need to be in the right place at the right time.

Michael Brown, a professor of astronomy at Monash University in Australia, noted that the 2019 OK asteroid was 1000 times weaker just three days before crossing Earth, making detection difficult.

Brown added that for the past month, the asteroid was relatively close to the sun so it was visible only at dusk.

NASA already detects larger asteroids than the asteroid 2019 OK. In 2005, the Congress instructed the space agency to find at least 90% of potentially dangerous asteroids larger than 140 meters by the end of 2020 (Asteroid 2019 OK was just 130 meters wide). According to Gizmodo the asteroid 2019 has already passed the Earth and is currently not a threat, others could be.
