That happens to also be round the sun?
Duh. 'Space' is mostly empty ...
Typical left brainer, confabulating a very organised space mission (and using a probe that may also be 'manoeuvrable), launched by professionals with 'some bloke' privately test launching some ballast into space. ;-(
Interesting:
"The asteroid material is so thinly distributed that numerous unmanned spacecraft have traversed it without incident.[6] Nonetheless, collisions between large asteroids do occur ... "
Fancy that ... and that space yet they still hit each other? ;-)
This one you mean?
"Due to the low density of materials within the belt, the odds of a probe running into an asteroid are now estimated at less than one in a billion."
So, it has been suggested that the Roadster will continue it's orbit for 1 Billion years and has an orbit that takes one year so it's odds on it *will* collide with an asteroid ... it's just a matter of time. ;-)
