15 km diameter is about the size of "thick" atmosphere. The mass of the air in this volume is something about 0.000..% . At speed of 80 km/sec, well, atmosphere

15 km diameter is about the size of "thick" atmosphere. The mass of the air in this volume is something about 0.000..% . At speed of 80 km/sec, well, atmosphere didn't slow it down much. And if there was only microbial life at that time it adapted and bounced back quickly.
- jvm___ 3y agoI was thinking of it's 80km/s wake through the atmosphere. Coming straight in it wouldn't be long horizontally but the clap of 15kms of atmosphere being pushed aside and then coming together behind it...
- two_in_one 3y agoMost likely 'behind' was filled by evaporated water and rocks. But that was quite a shock wave both in atmosphere and in the ground. It's strange that in managed to get only 2x of its diameter into the crust. I though it could just get though into magma. That would make the biggest volcano ever.
