Meteoroids entering the Earth's atmosphere leave only a bright footprint in the sky. Apparently, they also influence climatology, especially the fall of the meteoroid.
This is the conclusion reached by a group of researchers in the scientific journal Nature, after analyzing the influence of a meteoroid that crossed the atmosphere last year in the area of Tasmania. The meteoroid had a diameter of ten meters and when entering the atmosphere it was broken into small fragments by friction. However, once the sections were analyzed, they realized that they were larger than expected as they measured 0.41 micrometers.
The particles of this measure can remain in suspension for months in which they absorb and disperse sunlight. According to the researchers, this directly influences the climate of the meteoroid drop site. In fact, they point out that the influence of a meteor of 100 meters in diameter would be similar to that of the Pinatubo volcano in the Philippines. Likewise, the meteors that fall near the equator are the ones that have the greatest influence on the climate, since it is where more solar energy receives.
