If you've got a telescope looking at some distant star (I'm talking one of the millions you can't see with the naked eye) and suddenly it goes dim like something's in the way, it might be because something's in the way. Then you just track the occlusion of other cosmological objects around it to see if there's actually an object there.
Apparently people look for that car Elon Musk shot into space. That's not too much bigger. (It's got some weird solar orbit I think.) I think you just need a powerful telescope.
Dumb question. How can we see something so small in the black void that is space? 6 feet is stupidly puny for the stuff out there.
Occlusion.

blink comparator, yes?

Clyde Tombaugh discovered tiny, virtually invisible Pluto way back in 1930 using a thing called the "blink comparator."
it ain't always about size and power!
