Shape-of-a-Meteorite

For many years, people of science were curious about the nature and shape of meteorites that made their way to Earth. Today we have discoveries coming from a series of experiments and studies. They answer the question of how the meteorite finally gets this perfect shape at the end.

The research they took included erosion and melting that is provoked by the Earth’s atmosphere and begin when a meteorite penetrates the atmosphere. What is more interesting, nearly every meteorite that reaches the Earth is similarly shaped. The scientists have discovered the fact that more the edges are slender the more the meteorite will be prone to flip over. In case the edges are broad, the meteorite starts to quiver and rock back and forth.

Also, the third type of meteorite has been discovered, and it is considered perfect. Namely, the meteorite’s point or apex will lead and make them travel straightforward. The experiments they have conducted ideally matched what they previously detected while observing real meteorites. The correlation between the two represented an exact match. The aerodynamic postulates show us that the form of the object will influence its ability to fly correctly or straight. This gives us the answer to the question of the reason why so many meteorites that reach our planet are shaped in the same manner.

When they are in cosmic space, the meteorites are irregularly shaped. There are no rules to that. Thus, when they come in Earth’s atmosphere, they are on their last blazing flight. These pretended shooting stars don’t always succeed in making it to the ground. The few of them that do represent a long-time mystery. The flight through the atmosphere that we mentioned is going to modify the form of the meteorite. It will erode and melt until it gradually becomes reshaped.

Furthermore, there is a quarter of meteorites that aren’t shaped like some blob but are a perfect cone that is exactly like the one research provided. One of the techniques to achieve this is to make use of a clay object dunk in water. The current of the water will finally modify the shape of the clay object like it was really passed through the Earth’s atmosphere. In the end, we get the shape of the meteorite, which is neither too narrow or too wide.

It should be mentioned that this example is not the ideal one. It’s not a perfect simulation of the conditions that meteorites go through since being in the atmosphere the object is not steady and can move freely, spinning and tumbling. Another question that needs to be answered is what makes meteors stay in the same direction during their travel.

Additional research proved that a too wide object would drop deep down the water while tumbling. The object that is too narrow would quiver. When it comes to the perfect shaped object, it will fall straight down.

At last, the forces that influence melting and reshaping of meteors also form an object with ideal aerodynamics that keeps their posture steady. In that way, the meteors with perfect shape will finally reach the Earth. Besides these interesting facts, there is a plethora of things that we could discover from similar experiments about the nature of the universe.
