The Moon does not look completely dark when it is in the Earth’s shadow during a total solar eclipse because:
-there is a remnant glow from the hot lunar surface.
-atmospheric refraction bends red solar light onto the Moon.
-of light reflected from the clouds on the Earth, the earthshine.

Astronauts on the Moon look back at the Earth, a distance of about 400,000 km. If the cities of Washington, D.C., and New York are separated by about 300 km, what will the angle between them be when viewed from the Moon:
-3/4
-2.5 arc minutes
-1300°

A particular star is seen to cross the horizon at 10:00 P.M. (22:00 hours) on a particular night. When would this star cross the horizon on the next night, from the same location:
-10:00 P.M.
-9:56 P.M..
-This star will not rise the next night and will be seen again only after one year.

The zero point of the celestial coordinate known as right ascension (RA) is defined to be the:
-intersection of the Milky Way with the celestial equator
-point where the Sun crosses the celestial equator moving southward in its path across the sky.
-point where the Sun crosses the celestial equator moving northward in its path across the sky.
 
How many Moon diameters would fit between the so-called “pointer stars” in Ursa Major, the Big Dipper:
-5
-10
-15

If you follow Orion’s belt as it slopes down to the left, the first bright star you come to is.
-Polaris, the North Star..
-Sirius, in Canis Major.
-Spica, in Virgo.

1 arc minute is equal to
-1/3, 600°.
-1/60°.
-1/60 arc second.
 
The constellation whose stars are used as pointers to the north celestial pole in the northern hemisphere at this time in history is.
-Bootes, the shepherd, containing the bright star Arcturus.
-Ursa Major, the Big Dipper.
-Leo, the lion, containing the bright star Regulus.
 
The line of nodes of the Moon’s orbit is the
-major axis (longest diameter) of the Moon’s elliptical orbit.
-line of intersection between the Moon’s orbit and the Earth’s orbit (the ecliptic plane).
-line joining the points of the Moon’s nearest (perigee) and farthest (apogee) distances from the Earth.
 
If you follow a line through the “pointer stars” (the two stars in the bowl of the Big Dipper farthest from the handle) away from the open end of the dipper, the first moderately bright star you come to is
-Vega, in Lyra.
-Polaris, the North Star.
-Spica, in Virgo.
