Can two planets in our solar system collide?

I had this strange dream that a large planet was about to collide with Venus. Is that possible, and are there any planets in our system that are on a path that could collide in the near future? Planetary collisions are pretty rare, especially in developed systems like ours. read more

Any collisions between planets happened early in the Solar System, and they most certainly did. Our Moon was made by something Mars-sized smacking into the Earth very early on (over 4 billion years ago), and Mars has a giant, very old (about the same age, but ages are pretty uncertain once we get away from the Earth and Moon) crater that makes the northern part of the planet quite a bit lower than the southern part. read more

One such example of a scenario is the Andromeda Galaxy, which will collide with the Milky Way in around 3 billion years and might have a destuctive impact on the Solar system as it lies in the outer Milky Way and this event may cause collision of the planets. read more

About five years ago, In the journal 'Nature today', there was a report by two French scientists, using arcane mathematical models, predicted that in the distant future, the Earth and planet after planet will collide with each other as an inevitable part of the solar system's long-term evolution. read more
