Asteroid Impacts

We are increasingly concerned about what would happen to the Earth if an asteroid the size of the one that wiped out the dinosaurs hit the planet now.

But I wonder what the implications for the Earth would be, if such an asteroid hit Mars or Venus, and destroyed them? Should we not be keeping an eye on such potential planet-busters beyond the Earth? There would certainly be a substantial danger to Earth, from the colossal fragments that would go barrelling out in all directions.

NASA has a NEO,(Near Earth Objects), program to find asteroid the come close to earth. There is one very problematic situation that NEO cannot overcome as of today. That is objects entering the atmosphere from the sun. Just like the one that hit in Chelyabinsk Russia in 2014. It came out of the sun and we had absolutely no warning that it was on the way. This is disturbing and NASA is trying to resolve the problem.
