This is pretty wild... lot of talk about this. https://www.popsci.com/interstellar-object-solar-system
It looks gravitationaly dominated. If aliens needed this to move thru the solar system I'd be disappointed...it look like it took over a year to come in and out. Warp drive fail? Ho hum...slow day for astronomers I guess?
Amazing that they could detect a 1/4 mile object traveling at 44 kilometers per second at such a distance - there is still a possibility of imaging it as well.
Even if it's just a flying rock, it's still pretty cool that it came from outside the solar system in such an unusual trajectory.
