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
St Paul's Suite four movements: St Paul's Suite St Paul's Suite (Op. 29, No. 2), originally titled Suite in C, is a composition for string orchestra by the English composer Gustav Holst. It was written in 1912, but owing to revisions was not published until 1922. It is named after the St Paul's Girls' School in the United Kingdom, where Holst was Director of Music from 1905 to 1934. It was written in gratitude to the school, which had built a soundproof studio for him. This suite is the most famous of the many pieces he wrote for students at St. Paul's. The
