The interplanetary object, 1I/2017 U1, aka Oumuamua, caused quite a stir when it was detected passing through our solar system in 2017. It is even the subject of a controversial new book by respected Harvard astronomer, Avi Loeb, who argues that the object many actually be of intelligent origin.
This video of the YouTube astronomy channel, Astrum, takes a more sober look at 1I/2017 U1 and similar interplanetary interlopers, how they might have formed, how they get here, and what happens to them when they leave.
