Scientists Reveal Asteroids Hidden Near Venus Could Devastate Cities With Little Warning
Behind our nearest neighbour in the solar system, there are at least three asteroids that might destroy cities and hit Earth.
According to a recent study, Venus is obstructing our view of several near-Earth asteroids, which are big space objects that intersect or approach Earth’s orbit, increasing the risk of a catastrophic impact.
Brazilian, French, and Italian researchers discovered that a number of asteroids that orbit Venus are very difficult to identify since the Sun’s glare frequently obscures them.
The orbits of three asteroids in particular—2020 SB, 524522, and 2020 CL1—bring them perilously near to Earth.
Furthermore, because the asteroids’ orbits aren’t entirely stable, any change in gravity could cause them to veer in the direction of Earth.
Each of the three asteroids orbiting Venus has a diameter of between 330 and 1,300 feet, which means it may destroy entire cities and cause enormous fires and tsunamis.
Although the time for viewing them would be very brief, perhaps lasting only two to four weeks, the researchers pointed out that the Chilean Rubin Observatory might be able to detect dangerous asteroids approaching from our blind area near Venus.
One of these asteroids would discharge more than a million times the energy of the 1945 nuclear bomb dropped on Hiroshima, Japan, and create a crater more than two miles wide if it struck a city.
The worldwide team, headed by Valerio Carruba of São Paolo University, concentrated on asteroids known as Venus co-orbital asteroids, which share Venus’ orbit around the Sun.
“Twenty co-orbital asteroids of Venus are currently known,” the authors wrote in their report to the journal Astronomy and Astrophysics.
“Co-orbital status protects these asteroids from close approaches to Venus, but it does not protect them from encountering Earth,” they warned.
Because of their synchronised orbits, these asteroids are essentially like dancers who follow Venus as they both orbit the Sun, safely avoiding it.
Their erratic and erratic routes, however, have the potential to cross Earth’s track, and if they do so at the same moment as Earth, they may collide with us.
Due to their extremely low Minimum Orbital Intersection Distance (MOID), or the distance between their orbit and Earth’s orbit around the Sun, the near-Earth asteroids 2020 SB, 524522, and 2020 CL1 are the most worrisome.
An asteroid’s likelihood of striking Earth increases significantly with a smaller MOID.
With MOIDs of less than 0.0005 astronomical units (AU), or roughly 46,600 miles, these three asteroids close to Venus are closer to Earth than the Moon is on average.
NASA scientists raised the probability of an asteroid striking the Moon to 4% in April. After the likelihood of an impact on Earth increased to 3.1 percent, the greatest odds ever noted for a big asteroid, that prognosis was made.
According to the experts, a specialised space probe should be sent towards Venus because telescopes on Earth are not very good at seeing in all directions in space.
They claim that this is the only tool capable of completely mapping the dangerous asteroids that are “still invisible” and concealed in Earth’s blind region.
NASA ruled out the probability of 2024 YR4, another asteroid, hitting Earth in 2032 in February.
With a diameter of about 200 feet, the dangerous space rock still has a 1-in-25 chance of hitting the Moon.
It would detonate a detonation at least 500 times more potent than the atomic bomb dropped on Hiroshima if it struck Earth.
Scientists are still monitoring 2024 YR4 to determine its precise size and composition even though it has left the danger zone.
These important details could be very helpful to scientists worldwide if 2024 YR4 does make it to the moon in seven years.
Although the explosion would not impact Earth, it would be the first time that scientists could observe in real time as a known asteroid formed a lunar crater.
Scientists may learn more about other craters on the lunar surface thanks to the information acquired from this collision.
