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

The planets in out Solar System were formed from countless impacts
Moon Mercury Asteroids

My Very Enormous Martian Just Swallowed Up Neptune!
Most Voyagers Entering Mars Journey Serenely Until Nightfall
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
