Oumuamua - Or Should We Call It "Rama"?

Oumuamua is the mysterious interstellar visitor to our solar system that at first blush sounds a bit like the object in the science fiction novel "Rendezvous with Rama" by Arthur C. Clarke.

In that story, a large cylindrical object with an interstellar origin passes through our solar system. Oumuamua is also a large elongated object with an interstellar origin.

You may have to use your imagination...
So far though, our best information is that Oumuamua ("scout" or "messenger" in Hawaiian") is not 50km long and hollow like Rama: it's perhaps 400m long and apparently is a huge rock. Disappointing, but perhaps a relief at the same time.
“This is a fishing expedition,” said Avi Loeb, professor of astronomy at Harvard University and an adviser to the Breakthrough Listen project. “We are most likely not to find anything, but it is worth checking steadily our fishing hooks.
