Our Solar System

Calculate the eccentricity Eccentricity = measure of how flattened a planets orbit is Calculate the eccentricity of the ellipse below: length of major axis Formula: eccentricity = distance between foci length of major axis

What do the eccentricity values tell us? The closer the eccentricity is to zero the rounder the orbit Eccentricity of zero = perfect circle The closer the eccentricity is to 1 the flatter the orbit Eccentricity of 1 = a straight line

Which planet has the most perfectly circular orbit? Venus

Area A = Area B Area C

Which are more dense? Jovian or terrestrial
