  1. Chapter 7Survey of the Solar System

  2. The solar system formed from a cloud of cold gas and dust called the solar nebula about 4.6 billion years ago

  3. Evidence of countless impacts is found right next door

  4. Inner planets are vastly different than outer planets in terms of sizes, masses, and densities My Very Enormous Martian Just Swallowed Up Neptune!

  5. There is still minor debris left over from the formation of the solar system Rocky Asteroids - mostly found between the orbits of Mars and Jupiter

  6. There is still minor debris left over from the formation of the solar system Icy Comets – found in the outer parts of the solar system

  7. Dwarf Planets- orbit the Sun, nearly round shape, not a planet, star or moon

  8. Protoplanetary Disks New solar systems in formation!

  9. Exosolar Planets Planets that have been detected orbiting other stars!!!

  10. Detection of Exosolar Planets: Stellar Wobble • gravity of the planet causes • the star to wobble back • and forth • 1990s, used Doppler effect • to detect stellar wobbles

  11. Detection of Exosolar Planets: Planetary Transits

  12. Planetsin other solar systems

  13. New Earth-like Planet!

  14. First image of an exosolar planet around a star

  15. Discovery Methods KEPLER 2009 Nasa’s Space Interferometry Mission (2011) Terrestrial Planet Finder (2014, 2020)
