Stability of the Solar System is unlikely any of the planets will collide with each other or be ejected from the system in the next few billion years, and the Earth's orbit will be relatively stable. Since Newton's law of gravitation (1687), mathematicians and astronomers (such as Laplace, Lagrange, Gauss, Poincaré, Kolmogorov, Vladimir Arnold and Jürgen Moser) have searched for evidence for the stability of the planetary motions, and this quest led to many mathematical developments, and several successive 'proofs' of stability of the Solar System. The orbits of the planets are open to long-term variations. Modeling the Solar System is a case of the
Suite (music) dexterity from the pianist. Arnold Schoenberg's first use of the twelve-tone technique throughout an entire work was in his Suite for Piano, op. 25. Modeled on the Baroque keyboard suite, the piece consists of six movements entitled "Präludium" (Prelude), "Gavotte", "Musette", "Intermezzo", "Menuett" (Minuet, with Trio), and "Gigue". Other famous examples of early 20th-century suites are "The Planets" by Gustav Holst, a 'Suite for Orchestra' in which each piece represents the astrological significance of one of the seven uninhabited planets then known, as well as his First Suite in E-flat and Second Suite in F for Military Band.
