A meteor may have crashed into Mars's ocean.Well, if it had an ocean. They're still not sure about that. But if it did:
On a world believed to have lacked Earthlike plate tectonics, any tsunamis were probably triggered by a meteor slamming into a huge body of water.
Mostly, there seems to be a lot of nothing going on other planets, but once in a great while, something like that happens. Also, someday, maybe this:
There is a roughly 1-in-100,000 chance that the Earth might be ejected into interstellar space by a stellar encounter before this point, and a 1-in-3-million chance that it will then be captured by another star. Were this to happen, life, assuming it survived the interstellar journey, could potentially continue for far longer.[83]
