Nitrogen-Ice Fragment from a Pluto-Like World Could Explain 1I/2017 U1 (‘Oumuamua)
To the point
Alan P. Jackson and Steven J. Desch propose that 1I/2017 U1 ‘Oumuamua is a nitrogen-ice fragment from a Pluto-like planet ejected from another star system about half a billion years ago, and that its pancake shape, lack of a visible coma, and apparent solar-acceleration can be explained by nitrogen ice sublimation as it passed the Sun.
