The planets in out Solar System were formed from countless impacts

Inner planets are vastly different than outer planets in terms of sizes, masses, and
densities
Rocky Asteroids - mostly found between the orbits of Mars and Jupiter
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
There is still minor debris left over from the formation of the solar system
Dwarf Planets- orbit the Sun, nearly round shape, not a planet,
star or moon
Protoplanetary Disks
New solar systems in formation!
Exoplanets
Planets that have been detected orbiting other stars!!!
Detection of Exoplanets: Stellar Wobble Method
• • gravity of the planet causes the star to wobble back and forth
• 1990s, used Doppler effect to detect stellar wobbles

solar systems detected by the Stellar Wobble
method
