If this thing is coming to live with us for a little while, doesn't it deserve a better name than "object 2020 SO?" How about ... Lunacris?

&gt;the object might be the rocket booster of Surveyor 2, a robotic spacecraft that was launched to the moon on September 20, 1966.<p>When imaginative theorists speculate about a previous space-faring civilization, I always wonder about the possibility of space-junk. Wouldn&#x27;t we have observed their space-junk floating around the earth?

Don’t we have hundreds of “mini-moons”. When is something spacejunk and when is it a mini-moon?

The article makes it sound as if 2020 SO will be. cast back into space and not fall to earth. Is that the expected outcome?<p>Will this be visible to the naked eye similar to the International Space Station?
