Planetary Motion and Magnetism

What shape is Earth's orbit?

• circle

• ellipse

• square

• spiral

What is Kepler's 1st law?

• The planets orbit in an ellipse

• The plants move faster when they are closer to the sun and slower when they are further from the sun

• The farther a planet is from the sun the slower the orbit

  (P² = a³)

What is Kepler's 2nd law?

• The planets orbit in an ellipse

• The plants move faster when they are closer to the sun and slower when they are further from the sun

• The farther a planet is from the sun the slower the orbit

What is Kepler's 3rd law?

• The planets orbit in an ellipse

• The plants move faster when they are closer to the sun and slower when they are further from the sun

• The farther a planet is from the sun the slower the orbit

  (P² = a³)

Earth's wobble cause by the gravitational pull from the Sun & Moon. This changes the direction of the Earth's axis and will cause the north star to change over time.

• barycenter

• precession

• nutation

• ellipse
