It is very close considering the size of the solar system, galaxy, universe. It is almost as close as our Moon. It is certainly close enough to be labelled a NEO (Near-Earth Object) Anything closer than 4.3 million miles of Earths tracking orbit are considered potential hazards. This is less than 302,000 miles from Earth. Your car can travel 302,000 miles. Just not in space. Of course you will have to change your oil about a thousand times.
Also it could be on a long rbit around the Sun and actually reapproach the Earth on return or in several years or decades and actually be closer. This object was only discovered earlier this month.
In astronomical terms this is a close call. A haircut really.
There was closer a few years ago. Within the orbit of the moon.
That would be truly a lousy car!!
You change your oil ever 300 miles? It would be about 30 oil changes for me. Shoot, I ought to start using your used oil. I’d save a bundle.
