Asteroid misses Earth only: "City Killer" Asteroid 2019 OK came very close to Earth and surprised the scientists



Earth's Dangerous Asteroid Rips

Scientists uncovered an asteroid, which was referred to by some as a "city killer" who came closer to the earth this week than to the moon. The Washington Post told scientists they had no idea they were coming.

The asteroid 2019 OK raced to Earth at a speed of almost 24 km / s before passing by. According to NASA, it was about 75,000 kilometers from Earth on Thursday.

"It would have struck more than 30 times the energy of the atomic explosion in Hiroshima," astronomer Alan Duffy told the Sydney Morning Herald. Duffy called the Zooming Space Rock a "city killer".

Astronomers say this is not an immediate threat, but they admitted they had no idea that the Giant Rock was heading towards us because it was coming from the direction of the Sun.

The asteroid, about the size of a large boulder, became visible only a few days ago.

There are 20,000 near-Earth asteroids that occasionally pop up. In 2013, Russia was hit and injured 1,600 people.

At a conference in April, scientists from around the world were asked how they should respond to a supposed scenario in which an asteroid big enough to destroy a city is on the right track towards Earth meet in eight years.

The likely response would be the use of spaceships to kick-start the asteroid, a scientist said.

"All we have to do is change its speed a little faster or a little bit slower crosses Earth's orbit, it either crosses in front of or behind us," Dr. Lori Glaze, director of planetary research at NASA.
