A new analysis of chaos in the solar system reveals how planetary collisions are avoided over billions of years.
Earth probably shouldn't exist.
That's because the orbits of the inner solar system planets — Mercury, Venus, Earth and Mars — are chaotic, and models have suggested that these inner planets should have crashed into each other by now. And yet, that hasn't happened.
New research published May 3 in the journal Physical Review X(opens in new tab) may finally explain why.
Through a deep plunge into the models for planetary motion, the researchers discovered that the motions of the inner planets are constrained by certain parameters that act as a tether that inhibits the system's chaos. Besides providing a mathematical explanation for the apparent harmony in our solar system, the new study's insights may help scientists understand the trajectories of exoplanets surrounding other stars.
Unpredictable planets
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.
The problem of inner planet trajectories, however, is still too complicated to solve exactly. In the late 19th century, mathematician Henri Poincaré proved that it is mathematically impossible to solve the equations governing the motion for three or more interacting objects, often known as the "three body problem." As a result, uncertainties in the details of the planets' starting positions and velocities balloon over time. In other words: It is possible to take two scenarios in which the distances between Mercury, Venus, Mars and Earth differ by the slightest amount, and in one the planets smash into each other and in another they veer apart.

Not a secret anymore.
For the moon is hollow, but I have seen the sky.
interesting questions, but a very bad hypothesis
All I can say is that it was/is no accident.
Life - living things - needed a home in the universe.
I have read many times how if any number of variables about the earth never happened, life on earth would not exist.
It is no accident.
The solar system was “designed” with earth “in mind”.
More evidence that the Rare Earth Hypothesis might be right.

Far from nearby objects, even deep space probe location calculations are approximations. All models are wrong; a very small number are useful, sometimes.
Mathematics is eternal, without time, space, or energy, an inseparable branch of God. It's a perfect truth, while all our senses of the real world are approximations, technically lies. It's easy to ascribe God-tier perfection to mathematical models, but the perfection is only with the math itself, never its application to reality.
To believe that an exceedingly vast, systematically ordered universe, exquisitely finely tuned for life with intricate astounding complexity, can be all a result of purely natural processes requires much faith, more so than that the universe logically testifies to design, requiring a First Cause (at the least), that of a powerful being of supreme intelligence being behind the existence of energy and organization of matter.

to amuse myself, plus it does help me to visualize what can happen when different planetary bodies interact with each other.
Agree!
Thanks nickcarraway.

Yeah, good one.
