The meteorite is pale when approaching the Earth

We know that meteorite collisions can cause great catastrophes for the Earth as a cataclysm. But it seems that the Earth can also attack in reverse. Approaching the Earth will create vibrations for the structure of these meteorites.

Over the past decades, astronomers have analyzed the impact of meteors on Earth.New research has examined the hypothesis that Earth also has a significant impact on meteorites from longer distances that we think.


This finding is intended to answer a question that has been asked for decades. Most meteors will change their crimson color by merciless bombardments from cosmic objects. But some meteorites scattered inside the solar system have a faded color.

A hypothesis was made that they were subjected to collisions, revealing new rocks above their surfaces.

And now, the team led by Professor Richard Binzel, MIT Institute of Technology, has verified the validity of this hypothesis and produced an interesting result.

Binzel's team used a large NASA telescope in Hawaii to gather information about nearby Earth meteorites (NEAs), including a huge amount of data about the spectrum.

Through analysis, they checked the position of 95 NEAs over 500 thousand years, tracking their trajectories to find out how close they were to Earth.

They found that 75 of the observed 95 NEAs approached the Earth at a closer distance than the moon. Among them are about 20 faint meteorites.

Binzel has determined that, if a meteorite moves at a certain distance from the Earth, about a quarter of the distance between the Earth and the moon (about 100 thousand miles), it will undergo vibrations. Seismic shaking is strong enough to be able to bring new materials from the weathered layer onto its side. This makes the meteorite look 'new'.

They hypothesize that Earth's gravity has widened and hindered approaching meteorites.

Their hypothesis will be considered in 2029, when a dark meteorite called Apophis will approach the Earth at a distance of 40,000 km.

Binzel believes that it will have surface changes leading to color changes. 'The approach distance is probably close enough to cause a disturbance with the crumbs and stones on Apophis' surface.

'It will be very interesting to watch the seismic events that will happen to Apophis when flying along, watching, listening to it cracking and' moaning 'when flying near Earth.'
