Hazardous Asteroid went Undetected this week towards Earth 2021 SG

A Hazardous asteroid the size of a Boeing 747 cruised by earth this week, while scientists remained completely unaware of it.

NASA has called the giant asteroid 2021 SG and confirmed it had the wingspan of a 747, the height of the Cinderella Castle at Disney World, and was around half the size of the Great Pyramid of Giza.

It flew past the Earth on September 16 and was captured on camera by civilians.
It was also spotted by an asteroid tracker EarthSky, but scientists only became aware of the phenomenon the next day.

According to reports, it’s understandable that scientists had no warning as this asteroid came from a blind spot – the direction of the Sun.

According to EarthSky, the asteroid passed by at a very close distance towards Earth. Recorded as around half the distance between the Earth and the Moon.

It was closest to the planet at around 9:28 p.m. Irish time, passing by Greenland and Canada.

According to scientists, this was considered a very close call, as most asteroids of this size pass by earth much farther away.

Taking into consideration its large size and speed, which is 85,748 km/h that’s around 23.8 km. per second. The asteroid could have caused havoc if it made contact with our planet.

One of the reasons why it is hard to achieve the goal of finding 100% of all Near-Earth objects (NEO) is because some have orbits that help hide them from Earth-based observers.

However, the discovery of 2021 SG now shows the risk of unexpected asteroids coming closer to the Sun and this will remain a possible threat.

So what do you think? Does this means, Some hazardous asteroid can still escape from the earth observatory and Knock the Earth out?
