- Q5Precession iscaused by the gravitational pull of neptune, uranus, saturn, and jupiterthe center of mass between two objectsa change in direction of Earth's axis without a change in tilt which causes us to see a different north star in the skyslightly affects the seasons because there is a change in tilt of 18 degrees.30s
- Q6Nutation isthe center of mass between two objects, and the sun orbits ita change in the direction of Earth's axis without a change in tilt which causes us to see a different north star in the skya change in angle of Earth's tilt of around 1/2 degree, caused by the moon, affects seasons slightly, occurs every 18 years30s
- Q7The barycenter isThe center of mass of two or more bodies that are orbiting each other, or the point around which they both orbit. The sun orbits this.a change in angle of Earth's tilt of around 1/2 degree, caused by the moon, affects seasons slightly, occurs every 18 years.change in direction of Earth's axis so that we will see a new north star, occurs every 26,000 years.30s
