The United States joins the investigation of the “planetary killer”

The United States joins the investigation of the "planetary killer"

In fact, millennia could pass before the great shock that would destroy all life that existed at that time.

However, scientists at the Carnegie Institution for Science’s Earth and Planets Laboratory in the United States determined that 2022 AP7 is the greatest risk to Earth that has been discovered in the past eight years, the Spanish site 20 Minutes reported.

“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, originally published in The Astronomical Journal. Had happened.”

Sheppard said the 2022 AP7 event “provides 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 have information from the Dark Energy Camera (DECAM), located at Chile’s Cerro Tolo Observatory, where it produces images with a mosaic of 64 ccd and 570 megapixels.

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 that are about 1 kilometer in diameter, a size for which we call them ‘planet killers’,” Sheppard said 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.
