Fact of the Day: Non-Earthly Moon

In 1986, Duncan Waldron discovered 3753 Cruithne which some thought might of been Earth's secret 2nd moon. Turns out that it's a quasi-satellite with a 770-year horseshoe shaped orbit that at times will cross the Earth's orbit.  Needless to say, if we haven't found a 2nd moon now then we don't have one. Not even a super-tiny one.

But what if it's invisible? Okay, it can't be, but a girl can dream. :)
