It would also dig a deep crater. Depending on the depth of the hole, the atmosphere may be dense enough at the bottom that you wouldn't need anything more than an oxygen mask and a heavy coat to walk around outside. Some have proposed intentionally diverting comets into Mars to Terraform it, as they would add water and create craters which could be used as oases.

- Zuph 14y agoIt depends on the depth of a crater. A 15-20 mile deep crater would get you to Mt. Everest levels of density. Of course, that kind of a crater would require a direct impact from an object of this size, not a glancing impact.
