Kepler's first law states that...

• An imaginary line joining a planet to the sun will sweep over equal areas in equal periods of time.

  
  

• The orbits of the planets around the sun are ellipses, with the sun located at one focus.

• There is a mathematical relationship between a planet’s distance from the sun and the time it takes the planet to revolve around the sun (orbital period).

What is the difference between rotation & revolution in orbits?

• rotation of a planet is movement around another object

• rotation of a planet means it is spinning around on its axis

• revolution of a planet means it is spinning around on its axis

• revolution of a planet is movement around another object

Where on this diagram would the perihelion be located?

• left

• right

Kepler's third law states that...

• There is a mathematical relationship between a planet’s distance from the sun and the time it takes the planet to revolve around the sun (orbital period).

  
  

• The orbits of the planets around the sun are ellipses, with the sun located at one focus.

  
  

• An imaginary line joining a planet to the sun will sweep over equal areas in equal periods of time.
