Asteroids lurking in plain sight can now be detected using a new algorithm THOR


An asteroid is a relatively small chunk of rock minerals orbiting the Sun. As they orbit the Earth, they are described as Near-Earth Asteroids. Most of these rocky objects can be found orbiting the asteroid belt between Mars and Jupiter. But nearly 1,400 of these have been classified as potentially hazardous to Earth, meaning their orbits and size pose a reasonable threat to our safety. Most asteroids that enter Earth’s atmosphere cannot withstand the heat and burn up into meteorites before hitting the surface. However, some do not disappear completely.

About 65 million years ago, a small planet Collide with The earth And that’s the end of the age of dinosaurs. Not only them, it is believed that about 75% of animals die suddenly as a result of catastrophic events. After realizing the threat posed by asteroids to our existence, researchers tried to study these rocky objects. Finding and tracking asteroids is key to protecting the planet against their killer effects, according to researchers.

Several researchers working closely with the University of Washington have developed a new algorithm – called Tracklet-Free Helicopter Orbital Recovery, or THOR – to do the job. Their algorithm has now proven its usefulness, by detecting the first candidate asteroids, which have been confirmed by the International Astronomical Union’s Minor Planet Center.

The Asteroid Institute, a program of the B612 Foundation, ran THOR on its ADAM cloud-based astrodynamics platform. A comprehensive map of solar system provides astronomers with important insights into both science and planetary protection.

Unlike current algorithms, THOR does not require a telescope to observe the sky for asteroids to be discovered. communication speak.

The researchers hope that the new algorithm will help detect more hidden asteroids. “We are using the power of big computing to not only enable more discovery from existing telescopes, but also to find and track asteroids in historical images of the sky that we cannot see. previously went unnoticed because they were never intended for asteroid searches,” said the Asteroid Institute, Executive Director Dr. Ed Lu.
