Now, most planetary scientists agree that the solar system is unstable and that it is slowly tearing itself apart. The newer models also give astronomers a clearer look at the future—they show...
Thanks to the numerical experiments of the last two decades, we know now that the motion of the planets in the Solar System is chaotic, which prohibits any accurate

The long-term orbital stability of the inner planets in our Solar System is still an open problem : the orbits of Mercury, Venus, Earth, and Mars are
Shortly after discovering the law of gravity, Isaac Newton wondered whether it would allow our Solar System to remain stable. At face value, the problem seems trivial.
Despite this caveat, most evidence indicates that our solar system is astonishingly robust. Over the next five billion years, it is poised
Shortly after discovering the law of gravity, Isaac Newton wondered whether it would allow our Solar System to remain stable. At
An integration over 200 million years showed that the solar system, and more particularly the system of inner planets (Mercury, Venus, Earth, and Mars), is chaotic, with a
Despite this caveat, most evidence indicates that our solar system is astonishingly robust. Over the next five billion years, it is poised to retain its fundamental architecture—until
Most of the calculations agree that eight billion years from now, just before the Sun swallows the inner planets and incinerates the outer ones, all of
Most of the calculations agree that eight billion years from now, just before the Sun swallows the inner planets and incinerates the outer ones, all of the planets will still be in orbits very similar
Since the formulation of the problem by Newton, and during three centuries, astronomers and mathematicians have sought to demonstrate the stability of the Solar
The Solar System is stable on the time-scale of the existence of humans, and far beyond, given that it is unlikely any of the planets will collide with each other or be ejected
The long-term orbital stability of the inner planets in our Solar System is still an open problem : the orbits of Mercury, Venus, Earth, and Mars are highly stable over the lifetime of the Solar
The stability of the Solar System is a subject of much inquiry in astronomy. Though the planets have historically been stable as observed, and will be in the "short" term, their weak
