What does Kepler's 1st Law state?

• all planets move in elliptical shaped orbits around the sun

• all ellipses have one foci

• the area that a planet revolves around the sun is equal

• the speed that a planet revolves around the sun changes

An ellipse is drawn around two points called

• aphelion
• perihelion
• foci
• axis

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
