What causes the apparent retrograde motion of the planets?
A) It is an illusion created as we pass by a planet in our orbit (or the planet passes by us). B) It occurs when the planets reverse the direction of their orbits around the Sun. C) It is caused by the motion of planets around small circles that in turn go around bigger circles. D) It is an illusion created by our lack of depth perception in space. E) It is something we see only for planets that orbit the Sun in the opposite direction of Earth.
What would happen to Earth if we somehow moved our planet to the orbit of Venus?
A) Temperatures would rise only slightly, but enough to melt the polar caps. B) The fact that we have oceans would moderate the temperature change due to moving our planet, so temperature would hardly change at all. C) Being so much closer to the Sun would almost immediately cause the surface of Earth to melt, and all our cities would then be destroyed by the hot lava. D) Earth would suffer a runaway greenhouse effect and become as hot or hotter than Venus.
