So if a Comet coming towards the Sun knocks a large asteroid our of its orbit outside Mars

Give us the date you know you want to

Now, I know that the time interval would vary depending upon where it hits Earth in its orbit around the Sun. If it were the shortest distance the Asteroid would be sent plunging directly towards the sun, but would impact the Earth as we sweep right into its Path. Depending upon the speed imparted by the comet, the asteroid could hit Earth within a month of impact with the comet.


That ain't good. Do have a system set up to defend Earth.


I mean, let's face it, the United States has spent 17 Trillion on wars, but as best I can tell we have spent nothing to save the planet from an asteroid strike.

Is any country planning on some sort of defense?

Space is big, really big.

No asteroid will ever hit the earth, there is an ancient defence system in place

fleet would prevent that. And it would depend on where Mars is in relation to earth orbit at the time. lets put on mind here, its in there someplace

worrying about this is a bit like worrying that a skewed shot down the local pool hall will fly through the pool hall window, and go right through your bathroom window, as you're sitting there having a dump.

Comets go through the Asteroid belt all the time. One of these days, we will see a collision. Some parts of the Asteroid Belt are really crowded.
