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

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

• aphelion
• perihelion

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

• perihelion
• aphelion

Where is the planet moving faster

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

The farther away a planet is from the sun, the _______ it takes it to orbit the sun once. 

• longer
• shorter

What did Kepler discover about planets and their orbital speed?

• Planets closest to the Sun will orbit with the fastest orbital speed.
• Planets with the greatest mass will orbit the Sun with the fastest orbital speed.
• Planets furthest from the Sun will orbit with the fastest orbital speed.
• Planets with the least mass will orbit the Sun with the fastest orbital speed.

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
