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

What has an eccentricity of zero

• a straight line

• a large ellipse

• a circle

• a small ellipse

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
