The topic of artificial intelligence (AI) has become a major point of contention in today's society, generating numerous discussions and debates. Most people who use AI agree that its many applications need to be regulated. However, its increasingly significant contributions cannot be denied. To such an extent that there is now an AI that can detect dangerous asteroids.
In this article we'll explain everything you need to know about AI that detects dangerous asteroids.
what is an asteroid
Fortunately, artificial intelligence hasn't added any complications to our daily routines. In fact, scientists have used it to safeguard life on Earth. Recently, an algorithm successfully identified, for the first time, an asteroid considered dangerous to our planet.
An asteroid is a type of celestial object found in space, usually orbiting the Sun. These objects are smaller than planets, but larger than meteoroids, which are even smaller fragments. Asteroids are composed primarily of rocks and metals, and range in size from a few meters to several hundred kilometers in diameter.
They are found primarily in the asteroid belt , a region of the solar system located between the orbits of Mars and Jupiter. However, asteroids can also be found in other parts of the solar system, including orbits near Earth. These near-Earth asteroids are of particular interest to scientists and astronomers because they pose a potential collision risk with our planet in the future.
Most asteroids are remnants from the early formation of the solar system, and studying them can provide important information about how planets and other celestial objects formed . Furthermore, some contain valuable minerals and metals, leading to exploration of the possibility of using asteroids in the future to obtain resources for humanity.
AI that detects dangerous asteroids
When discussing asteroids that are very close to Earth, it is important to note that those with a minimum orbital intersection distance of 0,05 AU or less, as well as an absolute magnitude of 22 or more, are classified as potentially hazardous asteroids (PHAs).
Currently, all known PHAs, as well as other dangerous objects, are being monitored by the American Sentry surveillance system. The DiRAC Institute at the University of Washington, with lead developer Ari Heinze, designed the HelioLinc3D algorithm.
This system was specifically designed to work in conjunction with the Vera C. Rubin Observatory, currently under construction in northern Chile. It has proven capable of detecting asteroids with fewer observations than other methods for detecting space rocks. This is significant news, as the AI has already discovered a potentially hazardous asteroid, named 2022 SF289, which was reported in the International Astronomical Union's Minor Planet Electronic Circular MPEC 2023-O26.
The recently discovered potentially hazardous asteroid (PHA) has an estimated diameter of around 180 meters and is predicted to pass within 225.000 kilometers of Earth. This discovery is significant because it paves the way for the use of artificial intelligence (AI) in identifying hazardous asteroids. In fact, it could represent a turning point in this field of study. The AI system was responsible for detecting the asteroid, which has been named 2022 SF289 and is classified as a PHA. However, this does not mean it poses an immediate threat to our planet. Scientists assure us that the asteroid is not expected to collide with Earth in the near future.
Discovery
However, the discovery is noteworthy because it demonstrates that the algorithm can detect near-Earth asteroids with fewer and fewer observations than traditional methods currently require. The use of artificial intelligence (AI) has made it possible to uncover astronomical information with less data, which is advantageous because it shortens the time needed to make important discoveries.
This capability could be particularly crucial if a sizable asteroid is detected heading directly toward Earth. In such a hypothetical scenario, scientists could quickly deploy a planetary defense mechanism, such as the DART asteroid deflection system . "This is just a glimpse of what the Rubin Observatory will offer in less than two years, with HelioLinc3D discovering a new object every night," said scientist Mario Jurić, a member of the HelioLinc3D team.
This group of scientists predicts that the next wave of data-intensive astronomy will shape the future of observations. From HelioLinc3D to AI-assisted algorithms, "the next ten years of discovery will demonstrate advances in both algorithms and the development of new, large telescopes ," said Mario Jurić.
Why is it important to identify them?
Let's see what are the reasons why it is important to identify asteroids to know if they are dangerous or not:
- Impact risk: Some asteroids have orbits that bring them dangerously close to Earth. Identifying these asteroids and calculating their trajectories is crucial to evaluating and preventing possible catastrophic impacts. Although the probability of an asteroid colliding with Earth at any given time is low, the consequences of an impact can be devastating.
- Origin of the solar system: Asteroids are living fossils from the early solar system. By studying their composition and characteristics, scientists can obtain valuable information about how planets and other celestial bodies formed. This sheds light on the history and evolution of our solar system.
- Space resources: Some asteroids contain valuable resources, such as precious metals, minerals, and water. Exploration and possible mining of asteroids could provide essential resources for future space missions and the expansion of human activity in space.
- Scientific advances: The study of asteroids also provides us with a unique opportunity to expand our knowledge about the formation and evolution of celestial bodies.
- Space exploration: The identification and characterization of near-Earth asteroids are also critical to the planning and execution of manned and unmanned space missions.
I hope that with this information you can learn more about the AI that detects dangerous asteroids.
