Arizona State University astronomers report the strange 45-metre (148ft) object appears to be made of frozen nitrogen, just like the surface of Pluto, and Neptune’s largest moon, Triton.
Oumuamua looked like an asteroid but sped along like a comet. Unlike a comet it did not have a visible tail. Speculation flipped back and forth between comet and asteroid – and it was even suggested it could be an alien artefact.
Given that Oumuamua is unlike comets and asteroids – and something not seen before – “we cannot assume business as usual, as many scientists argue”, Loeb wrote in an email Wednesday. “If we contemplate something that we had not seen before, we must leave the artificial origin hypothesis on the table and collect more evidence on objects from the same class.”

So icy planets can be knapped like chunks of flint to produce circular icy slivers , interesting theory but it seems more convoluted and less likely than Avi Loeb's proposal.

Slowpoke scientists afraid to risk some taxpayer money..
They knew well ahead when it was coming by, I remember I posted in a ATS post they should prepare a greeting party for this
it is a once in a lifetime chance... but nahhh, doing something like that takes balls.. and they rather write books and give interviews.
Now we sit here and speculate and wave goodbye to a lost opportunity and possible alien tech.
