The asteroid Apophis will not hit the Earth for more than 100 years, says NASA

An asteroid from Earth will not attack for at least another 100 years. Earlier predictions claimed that the impact was supposed to occur in 2029, 2036 and 2068, but NASA now says we have more time left. However, we have in mind observational and defensive measures.

If nothing else, the 1110-foot asteroid is one thing that will scratch the list of human concerns in the foreseeable future. Apophis is an asteroid discovered in 2004 that, if it hits Earth, could kill 10 million people. His flight path in recent years has led many to conclude that it will affect the Earth at different times in the next 50 years, but now scientists see this as almost impossible.

Asteroids near Earth are one of the most terrifying natural phenomena that could cause mass casualties, in part because of their scale and the implications that surround them – as any dinosaur will tell you.

In her video series Field guide for planets, Dr. Sabine Stanley, a distinguished Bloomberg professor in the Department of Earth and Planets Morton K. Blaustein at Johns Hopkins University, said asteroids from Earth must meet several qualifications.

Watch the sky

The idea that a huge asteroid could come out of nowhere and end life on Earth is frightening. However, now it is much less frightening than just 40 years ago.

“The good news is that we now know a lot more about what’s out there,” said Dr. Stanley. „1980. only about 50 asteroids near Earth were known in the year; that number slowly increased to 500 by 1998, and that was the year Hollywood released not one, but two asteroid films –Deep impact and then Armageddon.

“In just two years, the number of known objects from Earth suddenly doubled to 1,000 by 2000, and the number increased rapidly thereafter, to about 20,000 by 2019.”

Dr. Stanley said only about 1,000 of it is more than a mile away, and global efforts continue in search of more. Knowing that these objects are there and in which direction they are traveling, we can keep an eye out for those that could pose problems for us.

The best attack …

Scientists will sometimes use a scale called the Torino scale to qualify the dangers of individual asteroids near Earth. It combines the size or energy of an asteroid with the probability of hitting Earth and is then assigned a number. The asteroid that killed the dinosaurs was rated 10, while the Tunguska event in Siberia – which leveled 2,000 square kilometers of forest – was rated 8. 8. No currently monitored object has ever received a rating above 4, which means a 1% chance of a collision.

“Suppose now, hypothetically, that we found an asteroid – say a large asteroid, Turin scale 10 – on the course of a collision with the Earth,” said Dr. Stanley. “What could we do?” Movie Armageddon suggests the use of nuclear bombs to smash to pieces and change the trajectory of parts. “

Would such an idea actually work? According to Dr. Stanley, NASA is really considering it. She said that in 2022, the double asteroid diversion test (or DART) will intentionally affect the small moon of the asteroid Didimos. Its moon is about 160 meters in diameter and doesn’t even have a real name, but the DART mission will test our ability to redirect asteroids of that size.
