Orbital Bodies Summative Review

What is the shape of a planets orbit?

• Circular

• A line

• An oval

• A star

What is the equation to calculate eccentricity?

• distance between the foci/length of major axis

• length of major axis/distance between the foci

• distance between the foci x length of major axis

• length of major axis + distance between the foci

If the distance between two foci are 5cm and the major axis is 15cm, what is the eccentricity of the planets orbit?

• .35cm

• .33cm

• 3.33cm

• 3.5cm
