It is NOT possible. It would take an extraordinary collision with another planet to change the orbit of Mars so that it would intersect with the earth, Since there are no other planets wandering at large within our solar system, the possibility of such an event is zero (0).

No, unless something really big somehow crossed over into our solar system and messed up the orbits.---and even thin it would be a matter of luck---like to small bullets shot at each other and hitting.

Mar cannot get closer than 34 million mile to Earth, and that's fairly rare. Venus is the planet that can get closest to Earth (in fact they are the two closest planets), 25 million miles. Any possible planetary collisions happened billions of years ago

The "stable orbits" mentioned by Acetek are "almost completely stable" for very long periods of time. However, there are exceptions to the stability. Computer simulations show that there are some very long term variations in orbital motion of other planets that could affect Earth. "....the answer to the question of the stability of the solar system—more precisely, will all the planets survive until the death of the Sun—is neither “yes” nor “no” but “yes, with 99 percent probability.” https://www.ias.edu/ideas/2011/tremaine-...

No, they are in two different and stable orbits. The only way that it could possibly happen would be for a rogue planet or other large mass to pass through the solar system and upset Mars' orbit and even at that it would be a tricky thing for Mars to get thrown off in the right direction to slam in to Earth. I wouldn't worry about it, we have many more world-ending disasters to worry about. :-)

Only if a rogue planet, or something larger, interacts with the solar system.

You have been on those Goofballs agan haven't you ?

No, they are in different orbits millions of miles apart.

Only if the sun disappeared and then the odds would still be astronomical.

Anything is possible given the right circumstances, such as another star wandering into our solar system and deflecting mars. But that is extremely unlikely. And we would know about it decades in advance.

not possible. Jehovah arranged all these stars perfectly

No.

Only if something acted on one of the planets to alter its orbit dramatically and force a collision
