A.   TRUE

B.   FALSE

A.   Both Venus & Mars had epicycles.

B.   Copernicus was wrong.

C.   Venus rotated about Earth.

D.   Venus revolved about the Sun.

A.   It travels from east to west each night.

B.   My life will be Topsy-turvy.

C.   It travels from west to east each night.

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

E.   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.

A.   in ellipses in random directions

B.   as far apart as possible

C.   bound by gravity of the planets

D.   around the Sun in roughly the same plane

A.   TRUE

B.   FALSE

A.   mass

B.   distance from the Sun

C.   radius

D.   speed of revolution

A.   the backward motion of a planet through the sky

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

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

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

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

B.   Jupiter's four large moons.

C.   Large numbers of stars in the Milky Way.

D.   Craters and mountains on the Moon.

E.   The full set of phases of Venus.

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

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

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.   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.

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

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

B.   The moon farthest away from Daniel.

C.   The moon closest to Daniel.

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