1.5 GA Orbital Motion - GA review

What is the eccentricity of a perfect circle?

• 1.000

• 0.005

• 0.001

• 0.000

According to your ESSRTs, which planet has a more elliptical orbit, Mercury or Venus?

• Mercury

• Venus

• Both have the same eccentricity

• Neither has an elliptical orbit

Which celestial body is inside the orbit of Jupiter ?

• Saturn

• Uranus

• Mars

• Neptune

Calculate the eccentricity of the Moon’s orbit given a focal distance of 42,000 km and a major axis length of 768,000 km using the equation: eccentricity = distance between foci / length of major axis. Round your answer to the nearest thousandth.
