  • Chapter 14; The SolarOrganization of the Solar SystemThe SunThe inner rocky planetsThe outer gas giantsComets, asteroids, meteorites
  • Chapter 14; The SolarOrganization of the Solar SystemThe SunThe inner rocky planetsThe outer gas giantsComets, asteroids, meteorites
  • Ch. 14 Main IdeasUnbalanced forces cause motion.What is the role of gravity in forming andmaintaining the shapes of the planets, the stars,and the solar system?The Sun is one of thousands of suns in theMilky Way Galaxy.
  • Ch. 14; Main Ideas cont.Suns differ in size, color, temperature.Astronomical units and light years bothcan be used to measure distancebetween planets.The stars are the source of all light in thesolar system.
  • Old View; Geocentric
  • Current View; Heliocentric
  • Kepler’s Laws First Law; Planets move in ellipsesSecond Law; When planets get close to the sun they move faster.Third Law; If you know how long it takes a planet to orbit the Sun you can calculate its distance from the sun.
  • Planet speed increases as distance from the sun decreases.
  • Measuring Astronomical DistanceAstronomical units (A.U.)1 A.U. = Earth’s average distance from theSun = 150,000,000 km.Be able to calculate distance from A.U.2.77 A.U. = (2.77)(150 million km) =415,500,000 km
  • The SunNuclear Fusion; H + H = HeOnly occurs under pressure = Sun’s core.The total mass of all the He is less than the H!!Where did the missing mass go?The lost mass is converted into energy...Produces immense heat and light.Pressure pushes out, gravity pulls into a sphere
  • Fusion Summary
  • Structure of the SunCoreRadiation zoneConvection zonePhotosphereChromosphereCoronaSunspots, prominences, solar flares & wind.
  • Four Rocky, Dense, Inner Planets
  • Four outer, gasseous, giants
  • Calculate
  • Comets, asteroids, meteoritesComet tails always point away from the Sun dueto the solar winds.
  • What’s the difference?Comets; dust, small rocks, ice; elliptical orbits; seenrarely in the sky.Asteroids; larger than comets, smaller than planets,circular orbits.Meteoroid; Size in between comet & asteroid.Meteor; A meteoroid streaking through air.Meteorite; A meteoroid when it hits the Earth.
