Planetary

What shape is Earth's orbit?

• circle

• ellipse

• square

• spiral

What is Kepler's 1st law?

• The planets orbit in an ellipse

• The plants move faster when they are closer to the sun and slower when they are further from the sun

• The farther a planet is from the sun the slower the orbit

  (P² = a³)

What is Kepler's 2nd law?

• The planets orbit in an ellipse

• The plants move faster when they are closer to the sun and slower when they are further from the sun

• The farther a planet is from the sun the slower the orbit

An ellipse is drawn around two points called

• aphelion
• perihelion
• foci
• axis

What is true about the area between points A, B and the Sun, and the area between points H, I and the Sun?

• The area between A, B and the Sun is the largest.
• The area between H, I and the Sun is the largest
• Both areas are equal in size
• There is not enough information to determine the areas
