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.

In simplest terms, what does Kepler's 3rd law state? 

• planets take a long time to orbit the sun
• there is no relationship between the distance of planet from the sun and the time it takes to orbit the sun
