Earth-Venus smash-up possible in 3.5 bn years: Study
Paris, June 11: A force known as orbital chaos may cause our Solar System to go haywire, leading to possible collision between Earth and Venus or Mars, according to a study released Wednesday.
The good news is that the likelihood of such a smash-up is small, around one-in-2500.
And even if the planets did careen into one another, it would not happen before another 3.5 billion years.
