A new astronomical study is causing great concern, as it reports that three large asteroids orbiting Venus could come dangerously close to Earth in the coming weeks. The research, published in the scientific journal Astronomy & Astrophysics, describes the asteroids as “almost invisible” due to the intense solar glare that makes it difficult to detect them.
Astronomers are concerned about three asteroids, 2020 SB, 524522 and 2020 CL1, which could, under certain conditions, enter a collision course with our planet . Their orbits are unstable and easily affected by small gravitational changes, which makes it difficult to predict their path.
Although there is no immediate indication of an impending impact yet, scientists are calling for more intensive monitoring and more investment in early detection of asteroids, especially those "hiding" in the bright light of the Sun.

"City-Killer" Asteroids: What Devastation Could They Cause?
The prospect of a collision with one of the three dangerous asteroids orbiting near Venus is causing concern in the scientific community.
With diameters ranging from 100 to 400 meters, asteroids 2020 SB, 524522 and 2020 CL1 have the capacity to level entire urban areas. The explosion from such a collision could release energy millions of times greater than that of the Hiroshima atomic bomb, creating craters over three kilometers in diameter and causing massive fires or even tsunamis.
The biggest problem is that these asteroids are almost invisible from Earth-based observatories. Their location — close to the Sun from our perspective — makes them extremely difficult to detect with conventional tracking devices, limiting warning and response time in the event of an imminent collision.
Although NASA and other space agencies routinely monitor near-Earth asteroids, asteroids moving in this part of our solar system escape observation.

Detection Is a Road Race
The Rubin Observatory in Chile, one of the most advanced ground-based telescopes, would have only two to four weeks to detect such an “invisible” asteroid heading toward Earth. That means extremely limited preparation time and practically zero margin for reaction.
The only effective solution the researchers propose is a specially designed space mission aimed at monitoring these areas from close range. Only in this way, they argue, will we be able to fully map and identify potentially hazardous asteroids.

The proposal for a space mission to monitor the regions near Venus is logical and necessary. But, as is often the case in astronomy, these are high-cost projects that require international cooperation and long-term planning. Until then, we are practically “hands tied” in the face of these sky-high dangers.
Ultimately, this issue highlights how vulnerable our planet can be and how urgent the need is for a more aggressive approach to planetary defense. It is not a matter of science fiction—it is a reality that humanity must start seriously addressing.
