Asteroids That Could Threaten Earth
Recent studies have unveiled a startling revelation regarding three formidable asteroids lurking behind Venus, posing a significant risk to cities on Earth. These asteroids, ranging in size from approximately 330 to 1,300 feet (100 to 400 meters) in diameter, are capable of unleashing catastrophic destruction, including widespread fires and tsunamis.
The study, published in Astronomy and Astrophysics, outlines the research conducted by an international team, led by Valerio Carruba from Brazil’s São Paulo State University. Currently, about 20 co-orbital asteroids are known to be in the gravitational influence of Venus, which conveniently shields them from our view.
The Hidden Dangers
What exacerbates this predicament is the instability of these asteroids' orbits. Unlike stable celestial bodies, their paths can unpredictably wobble or shift, potentially leading them toward a collision course with Earth due to gravitational disturbances.
Since ground-based telescopes have limitations when observing regions near the sun, researchers advocate for sending a dedicated space probe to Venus. This initiative is deemed essential to map the "invisible" hazardous asteroids that currently lie in a so-called blind spot for astronomers.
Rising Threats from Outer Space
Concerns surrounding potential asteroid impacts are becoming increasingly prominent. In April, NASA heightened its warnings by elevating the risk of an asteroid striking the Moon to four percent. This announcement accompanied a separate risk assessment indicating that the probability of a major asteroid collision with Earth has surged to 3.1 percent, marking the highest likelihood ever recorded.
Such developments emphasize the importance of ongoing research and preparedness efforts in the face of cosmic threats. As we continue to probe the depths of our universe, understanding and mitigating these risks remain a crucial challenge for scientists.
