US space command confirms interstellar asteroid hit earth in 2017

Scientists first noticed an interstellar meteor floating around in space around 2017. This rock fascinated scientists for some time until it suddenly disappeared. Five years later there was a second interstellar meteor spotting floating around the earth's atmosphere until it also suddenly went off the radar, or as scientists first believed, passed through to another galaxy. These two meteors were nicknamed Oumuamua and Comet Borisov. Unfortunately these scientists were never able to prove that these two meteors were actually interstellar. That was until April 2022, when the US space command confirmed in a memo that a new meteorite that struck Earth in 2014, also came here from another star system based off of the speed. The idea that there could be bits of interstellar meteor somewhere on the bottom of the ocean has stirred up lots of excitement in the scientist community, specifically to Harvard astronomists Avi Leob and Amir Siraj. Five years before in 2019 this duo had first
noticed Oumuamua in space and theorized that it was interstellar. Since this new meteor hit the Earth from behind, Siraj's calculations said the meteor was actually traveling at about 37.3 miles per second relative to the sun. He then mapped out the trajectory of the meteor and found it was in an unbound orbit, unlike the closed orbit of other meteors. This means that rather than circling around the sun like other meteors,it came from outside the solar system. "Presumably, it was produced by another star then got kicked out of that star's planetary system and just so happened to
make its way to our solar system and collide with Earth," Siraj said. But because Siraj got his information from a NASA database that doesn't say how accurate the information was, his research was unable to be published. After the confirmation from the US space command Siraj says "I thought that we would never learn the true nature of this meteor, that it was just blocked somewhere in the government after our many tries, and so actually seeing that letter from the Department of Defense with my eyes was a really incredible moment," Sense seeing this confirmation Siraj is working with a team of scientists to have his findings published. He even wants to try and recover some of the meteor that landed in the ocean but thinks it would be almost impossible due to the size of the project.
