Would it be possible to build a device or structure that could absorb the impact of an asteroid?
This is probably a stupid question but as the title says would this be possible. I'm imagining some kind of large structure which absorbs the impact rather than deflects it and then, a step further ...

Where on the orbit of 101955 Bennu would an impact deflection mission have the most chance of success
Asteroid Bennu has a slight change of impact with Earth in the year 2135 (or 2182) and thus is a prime candidate for a future deflection mission using an impact spacecraft.
Given that the orbit of ...
