I am thinking that if it is of a size that we can impact its tragectory AT ALL with todays technology, its gonna be small enough to burn up in the atmospjere. (?)
This one is around 30 meters across. How big does one have to be to make it thru to even impact earth, let alone do damage?
It’s not necessarily the size of an asteroid that determines whether it will survive entering the atmosphere, but the composition of it. In other words there are small ones that survive and comparatively larger ones that don’t. But, a mile wide one for instance is going to be a big problem no matter what it’s composition might be.
