Questions: 16 · 10 minutes
1. An observer uses the two outer stars of the Big Dipper’s bowl as pointers and extends their line away from the bowl’s base. Which star can this help locate?
Vega
Sirius
Betelgeuse
Polaris
2. How is the Big Dipper best classified?
A complete official constellation separate from Ursa Major
An open star cluster within Ursa Minor
An asterism forming part of Ursa Major
A zodiac pattern forming part of Leo
3. A constellation circles the north celestial pole without dipping below an observer’s horizon. What is it called for that observer?
Zodiacal
Circumpolar
Seasonal
Equatorial
4. In modern astronomy, what is a constellation officially defined as?
Any group of bright stars that forms a recognizable picture
One of the designated regions that divide the entire celestial sphere
A cluster of stars held together by gravity
A group of stars located at roughly the same distance from Earth
5. An observer at a mid-northern latitude sees Orion prominently in the evening during winter. Why is Orion generally not prominent in the evening sky about six months later?
Earth’s orbit has placed Orion near the Sun’s apparent direction, making it mainly a daytime-sky constellation then
Orion’s stars temporarily become too faint to see
Earth’s axial tilt moves Orion permanently below the southern horizon
Interstellar dust blocks Orion on a six-month cycle
6. What feature do the traditional zodiac constellations share?
They are all visible throughout the year from every latitude
They all contain a star brighter than first magnitude
They lie along the ecliptic, the Sun’s apparent path across the sky
They surround one of the celestial poles
7. An observer watches Scorpius rise in the east early in the night. If it remains above the horizon, where will it generally appear later because of Earth’s rotation?
Farther west across the sky
Closer to the north celestial pole
In the same position relative to the horizon
Farther east and lower in the sky
8. Which constellation is commonly recognized by five prominent stars forming a W or M shape in the northern sky?
Cygnus
Cassiopeia
Draco
Perseus
9. From the Northern Hemisphere, an observer follows the line of Orion’s Belt generally southeastward across the sky. Which bright star does this line help identify?
Sirius
Arcturus
Polaris
Antares
10. How many constellations are officially recognized by the International Astronomical Union?
48
112
100
88
11. In the Southern Hemisphere, an observer extends the long axis of the Southern Cross several times beyond the cross. What does this method approximately locate?
The point where the ecliptic meets the celestial equator
The direction of the south celestial pole
The center of the Milky Way
The position where the Sun will rise
12. Two stars appear next to each other in the outline of a constellation. What can astronomers conclude from that appearance alone?
The stars formed together at the same time
They orbit a shared center of mass
They lie in nearly the same direction from Earth but may be very different distances away
They have approximately the same size and temperature
13. A faint galaxy lies just across the official boundary separating two constellations, although it appears closer to the brighter stars of the first pattern. Which constellation contains the galaxy?
The constellation whose brightest star is nearest to it
Both constellations, because their visible patterns overlap
The constellation region on its side of the official boundary
Neither constellation, because galaxies are outside the Milky Way
14. Polaris, the current North Star, belongs to which constellation?
Ursa Minor
Ursa Major
Cassiopeia
Draco
15. Which constellation crosses the ecliptic but is not included among the twelve traditional astrological zodiac signs?
Orion
Ursa Major
Pegasus
Ophiuchus
16. Over several hours, most constellations appear to move from east to west across the sky. What mainly causes this apparent motion?
Earth’s revolution around the Sun
The stars’ motion around the center of the Milky Way
The gradual shift of Earth’s rotational axis
Earth’s rotation on its axis
