Asteroid impact avoidance in solar system

This article currently focuses a lot on avoiding asteroid impact on earth. However, avoiding asteroid impact on other planets in the solar system seems just as important. The idea is that if another planet is hit by a large enough asteroid to pull it out of orbit, those altered pull/repel forces of those planets may also alter the orbit of the earth, as it is kept in balance by their pull/repel forces. Chance of that happening seems way higher then just the chance of the earth itself being hit by a (large) asteroid.

Can the article mention this ?

Also, are there any plans on setting up "asteroid detection stations" at the moon or other planets to increase time between warning and actual impact (assuming such an event would actually happen within the next few hundred years or so).

Another thing I'm thinking of is that the creation of a lunar base could (in the future) also help in improving the capability of deflecting asteroids which could potentially impact earth or other nearby planets in the solar system, as the launch of missiles or crafts that can alter the asteroid trajectory will be easier (and they may get much more kinetic energy, due to absence air resistance at launch). --Genetics4good (talk) 17:00, 4 June 2021 (UTC)[reply]

Any asteroid large enough to notably change a planet's orbit would already be discovered. Asteroid impacts on other planets are basically academic and not a concern so NASA does not really have a public list. There is almost a zero chance of Earth being hit by any asteroid larger than 1 km in the next 100 years. Setting up a satellite closer to the Sun would help detect asteroid's interior to Earth's orbit such as the Atira asteroids. -- Kheider (talk) 23:57, 4 June 2021 (UTC)[reply]

a 1-km asteroid is huge, so that's not saying very much. A 500-m asteroid hit would be catastrophic. Certainly, the idea of another planet being hit by an asteroid big enough to perturb it sufficiently to affect the earth's orbit is pretty absurd. There are far more important things for Genetics4good to worry about.
