USA: they investigate an asteroid “planetary killer”

USA: they investigate an asteroid "planetary killer"

really, Millenniums may pass until a major shock occurs that will destroy all life that existed at the time,

However, scientists from the Earth and Planetary Laboratory at the Carnegie Institution for Science in the United States determined that 2022 AP7 is the biggest risk to Earth discovered in the last eight yearsSpanish site reported 20 minutes,

“Our study is one of the most comprehensive and sensitive discoveries ever made for objects within Earth’s orbit and near the orbit of Venus,” said study lead author Scott S. Shepard. astronomical journal,

Shepard pointed out that in 2022 AP7 . case of gives rise to “a unique opportunity to understand what kinds of objects lurk in the inner solar system”.,

The location of the Sun is no minor detail: until now neither 2022 AP7 nor the other two near-Earth-like asteroids could be detected by telescopes because the glare of our star prevented it.

But Carnegie scientists point out With information about the Dark Energy Camera (DECam)Which is located at the Cerro Tololo Observatory in Chile, where it images with a 64-CCD, 570-megapixel mosaic.

Now that three asteroids have been revealed thanks to the world’s most powerful digital camera, it may be a good time to remember that the United States space agency, NASA, managed to tweak an asteroid’s trajectory last month.

That celestial body didn’t represent a real threat to our planet, but it’s comforting to know that the DART spacecraft could be with it.

,So far we have found two large near-Earth asteroids about 1 kilometer in diameter, a size for which we call them ‘planet killers’.Shepard specified in a statement. A celestial body of these ratios “would have a devastating effect on life as we know it.”

“This would be a mass extinction event not seen on Earth in millions of years,” said the scientist, as it happened with the dinosaurs.

For now, Carnegie scientists stressed, there is no need to worry because asteroid 2022 AP7 will not come near our planet if it is closer to the Sun. What happens is that in future centuries its trajectory will become more synchronous with Earth’s trajectory, and then there is no way of knowing what will happen.
