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

According to Kepler's 3rd law, the square of the time it takes a planet to orbit (T) is directly related to the cube of the semi-major axis (a). This means the further away from the sun a planet orbits, _?_.

• the larger the constant k is.

• the smaller the constant k is.

• the longer the orbital period is.

• the shorter the orbital period is.
