Average distance from earth to the sun = 150 000 000 km. Prehelion (closest to the sun in the year- january 3) - 147 255 000 km. Aphelion (farthest from the sun in the year july 4) - 152 083 000 km. Earth is 8 minutes 20 seconds from the sun at the speed of light. Plane of earth"s orbit is plane of the ecliptic. Exogenetic energy: energy comes from outside our earth (>99%) Endogenetic energy: energy is produced inside (<1% heat from earth"s core) Convection: transfer of energy through uids or gases.
