The 2019 Discovery of a Meteor of Interstellar Origin

  title={The 2019 Discovery of a Meteor of Interstellar Origin},
  author={Amir Siraj and Abraham Loeb},
The earliest confirmed interstellar object, ‘Oumuamua, was discovered in the Solar System by Pan-STARRS in 2017, allowing for a calibration of the abundance of interstellar objects of its size ∼ 100 m. This was followed by the discovery of Borisov, which allowed for a similar calibration of its size ∼ 0 . 4 − 1 km. One would expect a much higher abundance of significantly smaller interstellar objects, with some of them colliding with Earth frequently enough to be noticeable. Based on the CNEOS…

The Inferred Abundance of Interstellar Objects of Technological Origin

The local detection rate of interstellar objects can allow for estimations of the total number of similar objects bound by the Milky Way thin disk. If interstellar objects of artificial origin are

Hyperbolic meteors: is CNEOS 2014-01-08 interstellar?

In 2019 a claim was made that the CNEOS 2014-01-08 meteor is interstellar. However, apparent interstellar meteors have been detected for decades. Moreover, they are expected from any meteor
