Earth and the other inner solar planets —Mercury, Venus, and Mars —“should be a chaotic messaa nd models have suggested that they should not exist.
“Planets constantly exert a mutual gravitational pull on each other – and these little tugs constantly make minor adjustments to the planets' orbits. The outer planets, which are much larger, are more resistant to little tugs and so maintain comparatively stable orbits.”
They should have should have crashed into each other by now. However, that hasn't happened.
