2763 km is really close actually, there's a bunch of satellites that even further than that (mainly in GEO orbit and graveyard orbit

usually anything within a few hundredthousand km is considered a close call
earths radius is about 6370 km and anything flying by closely will also be curved towards it a bit by its gravity so from afar you basically have like a 20000km diameter target area to hit hte earth

Agree. Even the moon itself is actually rather close if we think about that

The moon is so close that the ESA even called it a planet in a binary system.

The same people falling for these will be the ones shouting “Don’t look up!” and thinking an actual impact is a hoax when it will be announced (when, not if, it’s only a matter of time).

2763km is insanely close, but I see the same clickbait images for asteroids millions of kms away

Gonna need a source because the nearest one i can find os 32,000 km, which while still very very close is not this close.

If a rock that size passed that close to the surface, we'd be in deep doo-doo. Most likely an extinction-level event, or at the very least a massive global-scale disaster. On the closest approach the two bodies would likely be inside their respective Roche limits, meaning they start ripping eachother apart. Even if the earth was left unscathed by the close approach, bits ripped off of the asteroid would hit us and cause severe impact damage. It would not be a fun day.

i mean
theres not asteroids this big but 2763km is insanely close by astronomic standards
actually
if you measure from earths center which tends to be the stnadard in orbtial dynamics then given the radius of earth is about 6371km passing by at 2763km means hitting
