Sun 99.85% by mass Planets 0.1 % by mass Satellites and Rings Asteroids Comets Meteroids Dust Solar Wind (ionized gas)

The Solar System Inventory - Sedna The Solar System General Characteristics of Major Planets - Dynamical Nearly circular orbits (Mercury and Mars most eccentric) The Solar System

General Characteristics of Major Planets - Dynamical Nearly circular orbits (Mercury and Mars most eccentric) All orbit within 10o of Earths orbital plane The Solar System General Characteristics of Major Planets - Dynamical Nearly circular orbits (Mercury and Mars most eccentric) All orbit within 10o of Earths orbital plane All revolve in the same direction

All rotate in the same direction (except Venus) The Solar System General Characteristics of Major Planets - Radius The Solar System General Characteristics of Major Planets - Age Earth - Oldest rocks 3.9 billion yr (4.5 billion yr inferred)

Moon - 4.5 billion yr Meteorites - 4.6 billion yr Sun - 4.6 billion (theoretical) Universe - 12 billion yr The Solar System General Characteristics of Major Planets - Physical Properties Location
