The asteroid that wiped out the dinosaurs from Earth came from far behind the planet Jupiter. This was revealed in a recent study. This asteroid created a huge crater on the Yucatan Peninsula of Mexico 66 million years ago. Due to which the entire species of dinosaurs was wiped out.
Apart from this, 75 percent of the population of all living beings on earth was destroyed. It was like a catastrophe. Debris was spread all over the world. There was a tsunami. Fire spread. But now a study has been done, which claims that this asteroid came from outside our solar system. From far behind the planet Jupiter.

Scientists studied the ancient debris to find out what the asteroid was made of. This asteroid was carbonaceous. That is, C-type. This means that the amount of carbon in it was very high. Geochemist Mario Fischer Godde of the University of Cologne, Germany, and his colleagues have done this study.
The asteroid came from outside the solar system
Mario said that that asteroid does not resemble the asteroids present in our solar system. It came from outside. This is what ended the lives of the dinosaurs. This study was done recently Nature It has been published in the journal. The Cretaceous period ended after the collision of this asteroid. The Chicxulub crater was formed. This crater was not a small one.

A crater 180 km wide and 20 km deep was formed
It was 180 kilometers wide and 20 kilometers deep. Imagine how dangerous the impact of a carbon asteroid can be. The debris that flew from it is now deposited in many places in the form of clay. Iridium, ruthenium, osmium, rhodium, platinum and palladium are found in it.
Asteroids were identified due to special metal
All these metals are rare on Earth, but are common in asteroids. Scientists paid special attention to ruthenium. They examined the amount of ruthenium present in the clay. This metal has seven isotopes. Three were found in the debris from the collision. These isotopes confirm that the colliding asteroid was full of carbon.

How many types of asteroids are there?
Asteroids filled with ruthenium are rare in our solar system. The isotopes found in it seem to be from an asteroid that came from outside the solar system. C-type asteroids are the oldest substances in the solar system. They are also the most common. After this come the S-type asteroids filled with rocks and M-type asteroids filled with even rarer metals.
C-type asteroids provide evidence of the formation of the solar system. These were outside the solar system. Later, some gradually came inside the solar system. These usually keep moving in the asteroid belt formed between Mars and Jupiter. But the asteroid that destroyed the dinosaurs came directly from outside the solar system.
