NASA has found asteroids that orbit the sun – but it may have to widen your research. Astronomers believe in asteroids near Venus.
And if Venus are hide asteroids, that have not yet been detected, and can threaten the earth?
A new warning to this possibility, which addresses a “Invisible threat”, evaluating the “Risk of collision” Of these asteroids, read.
NASA has found asteroids that approach up to 1.3 astronomical (UA) units of our planet, but other asteroids, not detected so far, will be coorbiting venus. Pass unnoticed due to their particular orbits and the difficulties of visibility.
This analysis seeks to determine whether these venus coorbitals represent a threat to the earth and to what extent they can be observed from current or future observatories.
So far we know only 20 coorbital asteroids of Venus. Although their orbits prevent them from approaching the planet Venus itself, they can still get very close to the earth. These asteroids are considered potentially hazardous if they are more than 140 meters in diameter and pass less than 0.05 UA of the terrestrial orbit.
When the orbits of asteroids have a chaotic nature, They are harder to detect.
Researchers explain that Venus coorbitals have a “Tempo of Lyapunov” about 150 years-their orbits become unpredictable after this break. Thus, following the trajectory of a single long -term object is not reliable.
Therefore, the team of astronomers simulated The behavior of 26 asteroids “Cloned” with different orbital characteristics, along 36,000 years.
The simulations have revealed that some of these bodies, especially those that have orbital eccentricities less than 0.38, can indeed approach the earth, suggesting a real threat of impact.
However, detect These objects remain a challenge significant. The brightness of the sun makes them virtually invisible from the earth for much of the year, limiting the opportunities for detection to very specific observation windows, usually when asteroids are closer to Earth.
The future Vera Rubin Observatory may help identify some of these objects that are difficult to detect during their survey operations.
However, investigators argue that a more focused effort.
One of the proposed solutions involves sending a space observatory to the venus orbit, or to a solar lagrange point near Venus.
Observations from these places – especially if they are directed in the opposite direction of the sun – could significantly improve the detection of these hidden asteroids.
Is that even the small asteroids can cause catastrophic damage. There urgency in locating and following these dodge objects. THE risk may be silently Next to our neighboring planet, warns the.
