  1. Ch.2. • Solar System • Consisting of the Sun, planets, satellites, asteroids, plutoid (dwarf planet), comets &others. From http://sse.jpl.nasa.gov/planets/index.cfm

  2. The characteristics of the solar system • The sun occupies 99.8% of the total mass, but only 2% of the angular momentum • Seen from the sky far above the north pole, all the planets revolve around the Sun anticlockwise on the same plane. • They turn on their axis in the same direction with the revolution (exception, Venus & Uranus) • The planet’s arrays around Sun according to ‘Titius-Bode rule’ (D = 4 + 3*2n, where n is the order #) • The planets can be divided into two groups; inner (or terretrial) planets (from mercury to Mars) and outer (or major) planets (from Jupiter to Neptune). The two groups have definitely different sizes and compositions
