Five years ago Earth collided with an interstellar object, but no one noticed

In October 2017, astronomers have discovered the first in human history, interstellar object which has appeared in the Solar system is the asteroid Omoloi, the origin of which until now walks a lot of rumors. It turns out that people faced with objects from distant galaxies before, but just didn’t notice — so, at least, the researchers at Harvard University. According to them, faced with the Earth’s atmosphere in January 2014, the meteor is also an interstellar traveler.

To such conclusion came the astronomers AVI Loeb and Amir Siraj, carefully studied the data of the research Center NASA NEO on meteor impacts over the first half of 2014. They found that this cosmic object was flying towards Earth at a speed of 60 kilometers per second and was very small — the width does not exceed one meter. When the researchers calculated the trajectory of its flight, it became clear that the object was not orbiting tied to the Sun, so initially was not in our Solar system.

Based on all this, the researchers concluded that interstellar objects can be quite frequent guests in the Solar system, but astronomers simply do not notice them. And for good reason — they can carry a lot of interesting information, or even to bring life from distant planets.

Reaction of scientific community

Hearing the researchers, the astronomical community was divided into two camps. One part of experts thinks that science is too early to draw conclusions — astronomer from the jet propulsion Laboratory of NASA, Eric Mamajek is still skeptical about them, because they were made on measurements of only one event. However, among scientists there are those who support the opinion of his Harvard colleagues.

I think it would be reasonable to conclude that this high-speed object is indeed of interstellar origin. Interstellar objects can be quite common.

Who knows, maybe one of the interstellar travelers would be spacecraft from extraterrestrial civilizations? After all, astronomers have already speculated that the asteroid Omwamwi was sent by aliens.
