Any vehicle that can cross interstellar space in a reasonable time also has enough energy to destroy a planet, simply by crashing into it.

Depends on the size of the craft. If it is only a few meters across, I think it would just burn up in the atmosphere before it even reached the ground.

    If it burns up in the atmosphere with relativistic speed, it burns up the atmosphere.
