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
(P2 = a3)
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)
The center of mass between two objects. This is what the planets truly orbit.
barycenter
precession
nutation
ellipse
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
Earth's wobble cause by the gravitational pull from the Moon only. This changes the degree of the Earth's tilt and will cause seasonal changes.
barycenter
precession
nutation
ellipse
Due the the solar system's changing barycenter, the Sun is NOT stationary.
true
false
During the origin of our solar system the planets began to orbit the Sun because it was the least dense object.
true
false
The point in the earth's orbit where it is closest to the sun and moves the fastest.
aphelion/apogee
perihelion/perigee
The point in the earth's orbit where it is farthest to the sun and moves the slowest.
aphelion/apogee
perihelion/perigee
