A new study claims that Earth will not be threatened by lethal asteroids for the next 1,000 years. However, according to reports MetroThe study says smaller asteroids could still pose a serious threat to our planet.

The new study is detailed in a paper accepted for publication. Astrophysical Journal. According to these new findings, the asteroid with the highest risk of hitting Earth is 1994 PC1, about a kilometer in diameter. The chance of passing through lunar orbit is only 0.000151 percent, which is about 10 times the risk of other asteroids in the study.

Researchers involved in the study looked at the orbits of nearly 1,000 near-Earth objects (NEOs) larger than a kilometer. For the next 1,000 years, they saw nothing that seemed close to crashing into Earth. This doesn’t provide a 100 percent guarantee, of course, but it does provide some comfort when it comes to the risk of lethal asteroids.

Killer asteroids are more commonly known as planet-killing asteroids and are large enough to wipe out entire species. These massive asteroids are believed to have caused the extinction of the dinosaurs. Therefore, the risk of such asteroids colliding with Earth has always been a hot topic in the world of astronomy.

While the risk of a lethal asteroid hitting Earth in the next 1,000 years is low, that doesn’t mean smaller asteroids can’t threaten our planet. Asteroids large enough to destroy cities or create massive craters on our planet that could cause tsunamis, earthquakes and other natural disasters are still possible, although highly unlikely.

Also, NASA and others are working on ways to deal with asteroids, such as NASA’s DART spacecraft, which successfully collided with an asteroid last year and changed its orbit.
