And the Jeddah Astronomical Society revealed, in a report, that the asteroid is very small according to the standards of standard asteroids and will not be visible to the naked eye when approaching, as its apparent luminosity will reach about (+18.15), and if we assume that it is on a collision course, it is likely to become a fireball during its crash in The upper atmosphere of the Earth, an event that occurs several times a year for space rocks of this size.
By some estimates, there are hundreds of millions of small asteroids like 2021 RQ2, but they are extremely difficult to detect until they get very close to Earth, and in total the vast majority of them pass safely over much greater distances – usually much farther than the Moon.
Overall it’s a big feat to find these small, nearby asteroids in the first place, because they pass so fast, and there’s usually a short window of a few days before or after the close approach when that small asteroid is close enough to Earth to be bright enough but not so close. It is moving so fast in the sky that it cannot be detected by a telescope.
You take advantage of such opportunities to learn more about asteroids, such as the nature of their formation. These objects are like a time machine from the remnants of our solar system that retain many secrets of that era and can tell us more about the origin of our planet.
It is worth noting that this approach to the asteroid is the closest in the next ten years, and based on the latest high-resolution orbit calculations conducted by NASA’s Jet Propulsion Laboratory, it is confirmed that it will not collide with Earth in the near future.
