“Anything that passes within 120 million miles is considered a Near Earth Object (NEO)...”
The Moon is 238,900 miles away.
The Sun is 93 million miles away.
I do seem to recall an asteroid that passed between us and the Moon. So that to me is pretty close. IIRC it was not observed until AFTER it had passed by us. Incoming the sun was in our eyes and we couldn’t see it. Seriously!
Mercury, Venus and Mars are sometimes less than 120 million miles from earth...not to mention Phobos and Deimos.
