Kepler's Law

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

Where is the planet moving faster

• Position A to B

• Position B to C

• Position H to I

• Position I to J

Kepler's 2nd Law deals with

• the shape of the planets' orbits

• the area the planet travels

• the length of time/period it takes the planet to orbit the sun

Planets orbit the Sun in a shape called a(n)

• circle

• ellipse

• focus

• perihelion
