How do you calculate the eccentricity of the ellipse? Esrt pg. 1

• Distance between Foci divided by Length of Major axis

• Major axis divided by Foci

• Major axis divided by Minor axis

• Minor axis divided by Major axis

• 0.093

• 0.334

• 0.500

• 0.750

Where should you mark the letter 'S' on the ellipse?

• At the center

• At the top

• On the right side

• On the left side

Where should you place the 'X' to indicate the fastest velocity point of the asteroid?

• At the bottom

• Opposite side of 'S'

• Same side as 'S'

• At the center

What conclusion can be drawn if the asteroid's eccentricity is greater than that of a planet?

• The asteroid's orbit is less elliptical

• The asteroid's orbit is more elliptical

• The asteroid's orbit is circular

• The asteroid's orbit is the same
