The mass budget necessary to explain ‘Oumuamua as a nitrogen iceberg

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