Galactic center affects solar system.Galactic center affects solar system solar system, the sun and the surrounding planets, natural satellites, dwarf planets, asteroids, meteoroids, and comets that are bound by its gravity. The sun is by far the most massive part of the solar system, containing almost 99.9% of the system's total mass. Since ancient times, astronomers have wondered why theplanets of the solar system are located where they are. One of the famous empirical facts about this configuration is the Titius-Bode law Titius-Bode law or Titius's law: see Bode's law. , observed by Johann Titius in 1766 and published by Johann Elert Bode Johann Elert Bode (January 19, 1747 – November 23, 1826) was a German astronomer known for his reformulation and popularization of the Titius-Bode law as well as his works to determine the orbit of Uranus, for which he also suggested the name. in 1772. It says that the radii ra·di·i n. A plural of radius. radii Noun a plural of radius of the orbits of the planets from the asteroid belt out (except Neptune) form a geometric progression, each radius being just about twice the radius of the orbit just inside it. Jaume Llibre and Conchita Pinol of the University ofBarcelona in Spain say they can explain the Titius-Bode law by gravity if they take into account the sun's motion around the center of the Milky Way galaxy Milky Way Galaxy Large spiral galaxy (roughly 150,000 light-years in diameter) that contains Earth's solar system. It includes the multitude of stars whose light is seen as the Milky Way, the irregular luminous band that encircles the sky defining the plane of the galactic . This sets up a four-body problem involving the gravitational interaction among the galactic center, the sun, a given planet and the planet just inward of the given planet. Presenting their calculations in the May ASTRONOMICAL JOURNAL, the researchers say that no previous attempt to explain the law has taken into account the center of the galaxy. |
