B.   TRUE

A.   Copernicus was wrong.

B.   Both Venus & Mars had epicycles.

C.   Venus revolved about the Sun.

D.   Venus rotated about Earth.

A.   It travels from west to east each night.

B.   My life will be Topsy-turvy.

C.   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.

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

E.   It travels from east to west each night.

A.   in ellipses in random directions

B.   around the Sun in roughly the same plane

C.   bound by gravity of the planets

D.   as far apart as possible

A.   TRUE

B.   FALSE

A.   distance from the Sun

B.   mass

C.   speed of revolution

D.   radius

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

B.   the west to east motion of a planet against the stars

C.   the backward motion of a planet through the sky

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

A.   Craters and mountains on the Moon.

B.   The full set of phases of Venus.

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

D.   Jupiter's four large moons.

E.   Large numbers of stars in the Milky Way.

A.   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.

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

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

D.   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.

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

A.   The moon closest to Daniel.

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

C.   The moon farthest away from Daniel.

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