1. Our Solar System

2. 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

3. 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

4. Which planet has the most
perfectly circular orbit?
Venus

5. Area A =
Area B
Area C

7. Which are more dense?
Jovian or terrestrial
