lesson 2

• Large Scale Features of the Solar System- Much of the mass of the Solar System is concentrated at the center (Sun) while angular momentum is held by the outer planets
• Large Scale Features of the Solar System-Orbits of the planets elliptical and are on the same plane.
• Large Scale Features of the Solar System-All planets revolve around the sun.
• Large Scale Features of the Solar System-The periods of revolution of the planets increase with increasing distance from the Sun; the innermost planet moves fastest, the outermost, the slowest;
• 1700s Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace independently thought of a rotating gaseous cloud that cools and contracts in the middle to form the sun and the rest into a disc that become the planets. This nebular theory failed to account for the distribution of angular momentum in the solar system.
• Nebular Hypothesis-1700s Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace independently thought of a rotating gaseous cloud that cools and contracts
