A.   Venus revolved about the Sun.

B.   Venus rotated about Earth.

C.   Both Venus & Mars had epicycles.

D.   Copernicus was wrong.

A.   It travels from east to west each night.

B.   If I take a picture of it each week at roughly the same time, against the fixed stars, and connect the dots, it will appear to travel from west to east.

C.   It travels from west to east each night.

D.   Each night, it makes a loop in the sky.

E.   My life will be Topsy-turvy.

A.   around the Sun in roughly the same plane

B.   bound by gravity of the planets

A.   FALSE

B.   TRUE

A.   mass

B.   speed of revolution

C.   radius

D.   distance from the Sun

A.   the apparent backward motion of a planet against the fixed stars

B.   the backward motion of a planet through the sky

C.   the east to west motion of a planet compared to the viewer's horizon

A.   Jupiter's four large moons.

B.   Large numbers of stars in the Milky Way.

C.   Craters and mountains on the Moon.

D.   The full set of phases of Venus.

E.   A given planet's speed among the background stars varies with time.

A.   As seen from Earth's surface, planets rise in the east and set in the west, even when they undergo retrograde motion.

B.   According to Kepler's first law, the orbit of planets are ellipses with the Sun at one focus; there is no object at the second focus.

C.   Copernicus' model of the Solar System was accepted shortly after being proposed, because it provided significantly more accurate positions of the planets than did the Ptolemaic system.

D.   Our observations of a full or gibbous Venus provide evidence against the Ptolemaic, Earth-centered model of the Solar System

E.   If you lived on Mercury, you would notice that Earth exhibits retrograde motion for a while every year.

A.   The moon farthest away from Daniel.

B.   There's no way to determine which moon rotates the fastest without knowing their relative masses.

C.   The smallest moon will orbit the fastest, just like Mercury (the smallest planet) orbits the Sun the fastest.

D.   The moon closest to Daniel.
