Scale and Orbits Review

Which statement is accurate about the spacing of the planets in our solar system?

• All planets are equally spaced apart and from the Sun.

• The first four planets are far apart and the last four are close together

• The first four planets are close together and the last four are far apart

• The planets get farther and farther apart the farther away from the Sun they are.

Why do Uranus and Neptune orbit the Sun so slowly?

• They are too large to orbit any faster

• Their inertia/velocity does not need to be as great to balance out the Sun's gravitational pull

• Their inertia/velocity needs to be very large to balance out the Sun's gravitational pull

• They orbit slowly by random chance

Which of Newton's Laws explains the concept of inertia?

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• Newton's 4th Law

What would most likely happen to a planet that had more inertia/velocity than the Sun's gravitational pull?

• It would be pulled into the Sun

• It would be pulled into another planet

• It would have more moons

• It would not orbit the Sun, but would speed past it.
