The debris snuffed out life on Mars and covered half of Mars in a 20 Km deep blanket of crud. It seems to have tilted Mars as well, giving it a new geological set of Poles. And there are solid rock comets as well, from the rock of the planet. It makes me wonder whether the flood in Noah's day was a huge hit by the water of the Exploded planet. It can only be an object that generates heat by nuclear decay.
Someone needs to do something.
