The origin of the interspecific object 1I / ‘Oumuamua, has been explained. In a companion paper (Jackson & Desch, 2021), we show that there would be a group of N2 ice with 45 mx 44 mx 7.5 m axes at the time of observation depending on the albedo, non-gravity acceleration, and lack of CO. see. or CO2 or dust. Here we show that the surface effects of Kuiper belt-like objects Pluto (KBOs) would have generated and extracted ~ 10 ^ 14 collision fragments – about half of them H2O ice fragments and half of them N2 ice fragments – such as as a result of the dynamic instability that reduced the primordial Kuiper belt. We show consistency between these numbers and how often we would view interstellar objects like 1I / ‘Oumuamua, and more comet-like products like 2I / Borisov, if other stellar systems add eliminate these efficient substances like the Sun; we conclude that differential KBOs and dynamic instability that disrupt impact-generated particles may be near-universal among extrasolar systems. Galactic cosmic rays would erode these particles over 4.5 Gyr, so that fragments are small fractions (~ 0.1%) of long-lived Oort comets, but C / 2016 R2 could be an example. We make out ‘Oumuamua was sent out about 0.4-0.5 Gyr ago, from a young stellar system (~ 10 ^ 8 yr), which we think was in Perseus’ arm. Things like ‘Oumuamua can directly examine the exoplanet-type surface results so far:“ exo-plutos ”. Oumuamua is probably the first exoplanet sample brought to us.
