10
Most scientists agree that the universe is
an illusion.
~6,000 years old
~13.7 billion years old
~4.6 billion years agold
11
What is the eccentricity of Earth's orbit according to the diagram?
Eccentricity = 299,000,000 - 5,000,000
Eccentricity = 5,000,000 + 299,000,000
Eccentricity = 299,000,000km / 5,000,000km
Eccentricity = 5,000,000km / 299,000,000km
