If nobody will ever see it again, then mankind must have failed as a species some time in the near future.

It's still there, it's trajectory known, and given even mildly futuristic tech it can be reached.

I disagree.

It's going to be long gone, and very difficult to ever find again. It's trajectory is only somewhat known; there is always uncertainty in the measurement.

Also, from what I understand now, this sort of thing should be a roughly yearly occurrence, given the number of rogue comets out there. It will be easier for "mildly futuristic tech" to just go after another one that comes along.

When I first saw this I sorta rolled my eyes, but actually, given the lack of a coma, I think that it's actually a real, though *very* remote possibility. A probe would be one sort of object that we would expect to come from interstellar space and not show a coma.

At the time that I wrote that, I was unaware how common this occurrence should be. I've since seen an estimate that this should be a yearly occurrence, rather than a once in a millennium occurrence. I've since forgotten the source, though.

Again, I don't think it's an at all *likely* possibility, but the lack of a coma makes it a possibility, even though it's pretty much the first thing we shave away with Occam's Razor.

Wouldn't it be fun if it had a look at the Solar System, and decided the next one was better?
Bet I can get to the next one before the fuel runs out....

Rama was using Sol for a slingshot gravity assist in the novel.

The fact that this thing is "highly elongated" and not the usual semi-spherical or potato-shaped object makes it weird. I wonder how many heliocentric asteroids or other bodies match this description.

400 m long, metallic, no ice, not surrounded by dust.

This one is REALLY strange. I wonder what it will do on perihelion.

EDIT: Ah, no, already passed perihelion in September without solar orbit insertion.

Well, we don't have that many exo-comets for comparison, so who's to say what's strange?

Well, on a scale of strange objects, the most similar object with such properties is the NEO J002E3.

Rama confirmed.

And the first comment beat me to that reference. Great timing.
