Kepler’s Laws

Planets orbit the Sun in a shape called a(n)

• circle
• ellipse
• focus
• perihelion

An ellipse is drawn around two points called

• aphelion
• perihelion
• foci
• axis

The place where a planet is closest to the Sun as it orbits the Sun is called the

• perihelion
• aphelion

The place where a planet is farthest away from the Sun in its orbit around the Sun is called the

• aphelion
• perihelion

Where is the planet moving faster

• Position A to B
• Position B to C
• Position H to I
• Position I to J

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

Kepler's 2nd Law deals with 

• the shape of the planets' orbits
• the speed/area the planet travels 
• the length of time it takes the planet to orbit the sun

Kepler's first law states that the orbits of the planets are oval in shape or 

• ellipses
• perfect circles

Which diagram shows a planet with the least eccentric orbit?

• 1
• 2
• 3
• 4

What shape are the orbits of all planets in our solar system? 

• circular
• cylindrical 
• elliptical
• none of these
