Minor Bodies of the Solar System Chapter 7
Kepler’s Laws • 1. Planets orbit the sun in elliptical orbits with the sun at one focus of the ellipse
Keper’s Second Law • As a planet moves in its orbit, a line connecting the planet to the sun sweeps out equal areas in equal times
Kepler’s Third Law • P2 = a3 (provided the period is in Earth years and the semi-major axis in astronomical units)
Main Asteroid Types • C type: carbonaceous, low albedo • S type: stony or stony-metallic, redder • E type: high albedo, magnesium silicate • D type: very dark and red • M type: mostly iron and nickel • E, S, and M types may be fragments from a larger body that underwent differentiation
Asteroid Light Curves • Antigone
