Recently, a nitrogen iceberg was proposed as a possible origin for the first interstellar object, 1I/2017 U1, also known as ‘Oumuamua. Here, we show that the mass budget in exo-Pluto planets necessary to explain the detection of ‘Oumuamua as a nitrogen iceberg chipped off from a planetary surface requires a mass of heavy elements exceeding the total quantity locked in stars with 95% confidence, making the scenario untenable because only a small fraction of the mass in stars ends in exo-Plutos.

On the Possibility of an Artificial Origin for `Oumuamua
Science offers the privilege of following evidence, not prejudice. The first interstellar object discovered near Earth, `Oumuamua, showed half a dozen anomalies relative to comets or asteroids in the
Preliminary Evidence That Protoplanetary Disks Eject More Mass Than They Retain
If interstellar objects originate in protoplanetary disks, they can be used to calibrate the fraction of mass that such disks eject. The discoveries of interstellar objects 1I/‘Oumuamua and
Research Programs Arising from 'Oumuamua Considered as an Alien Craft
The controversial hypothesis that ‘Oumuamua (1I/2017 U1) was an alien craft dominated by a solar sail is considered using known physics for the two possible cases: controlled and uncontrolled flight.
The New Astronomical Frontier of Interstellar Objects
The upcoming commencement of the Vera C. Rubin Observatory’s Legacy Survey of Space of Time (LSST) will greatly enhance the discovery rate of interstellar objects (ISOs). ‘Oumuamua and Borisov were

Convection in a volatile nitrogen-ice-rich layer drives Pluto's geological vigour.
TLDR
It is reported, on the basis of available rheological measurements, that solid layers of nitrogen ice with a thickness in excess of about one kilometre should undergo convection for estimated present-day heat-flow conditions on Pluto and shown numerically that convective overturn in a several-kilometre-thick layer of solid nitrogen can explain the great lateral width of the cells.

Could Solar Radiation Pressure Explain ‘Oumuamua’s Peculiar Acceleration?
'Oumuamua (1I/2017 U1) is the first object of interstellar origin observed in the solar system. Recently, Micheli et al. reported that 'Oumuamua showed deviations from a Keplerian orbit at a high

TLDR
‘Oumuamua—the first known interstellar object to have entered the Solar System—is probably a comet, albeit with unusual dust and chemical properties owing to its origin in a distant solar system.
