CNEOS 2014-01-08
CNEOS 2014-01-08 is an interstellar object reported in June 2019 by astronomers Amir Siraj and Avi Loeb, Abraham Loeb, and confirmed by the United States Space Command in April 2022. The discovery was publicized in 2019 in a preprint announcing a meteor detected on 8 January 2014 near the northeast coast of Papua New Guinea. Discovery and confirmation According to the researchers, the meteor originated from an unbound Hyperbolic trajectory, hyperbolic orbit with a Margin of error, confidence of 99.999%. The interstellar candidate was found in data from the Center for Near-Earth Object Studies. The estimated Velocity, speed of the meteor, around , was likely produced in the innermost cores of another stellar system. A 2019 study by Jorge I. Zuluaga published as a research note by the American Astronomical Society concluded that even if the direction were completely unknown, the Law of total probability, probability that CNEOS 2014-01-08 was Orbital eccentricity, hyperbolic would ...

Interstellar Object
An interstellar object is an astronomical object (such as an asteroid, a comet, or a rogue planet, but not a star) in interstellar space that is not gravitationally bound to a star. This term can also be applied to an object that is on an interstellar trajectory but is temporarily passing close to a star, such as certain asteroids and comets (including exocomets). In the latter case, the object may be called an interstellar interloper. The first interstellar objects discovered were rogue planets, planets ejected from their original stellar system (e.g., OTS 44 or Cha 110913−773444), though they are difficult to distinguish from sub-brown dwarfs, planet-mass objects that formed in interstellar space as stars do. The first interstellar object which was discovered traveling through our Solar System was 1I/ʻOumuamua in 2017. The second was 2I/Borisov in 2019. They both possess significant hyperbolic excess velocity, indicating they did not originate in the Solar System. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
