At 9 p.m., Orion is low in the east on Ari's chart. Where will it be later that night?
- In the same spot until dawn

“not to scale” Using the orbit diagram, in which month is Scorpius high in the midnight sky, Jun?
Orbit diagram seen from above the North Pole (not to scale). The Sun is in the center. Earth is drawn at four positions, moving counterclockwise: A (September), B (December), C (March), D (June). Far beyond the orbit: Pisces beyond A, Orion beyond B, Virgo beyond C, Scorpius beyond D. At each position, Earth's night side faces away from the Sun.

Kira reads that Orion and Scorpius are never up at the same time from the mid-northern US. Why not?
- They sit on opposite sides of the sky
- One of them stops shining
- Earth's spin changes their shapes each night
- They orbit each other
“not to scale” Using the orbit diagram, in which season do evening skies over the US show Orion best, Luz?

- Winter
- Summer
- Late spring
The height of Polaris above the horizon equals your latitude. In a town at about 40° north, how high does Milo see Polaris?

Star chart (dot-and-line), Northern Hemisphere, facing north. Seven dots joined by lines make the Big Dipper, part of Ursa Major: four stars form the bowl and three form the handle. The two outer bowl stars are labeled Merak (bottom) and Dubhe (top). A dashed line from Merak through Dubhe reaches a star labeled Polaris.
At 8 p.m., the Big Dipper is above Polaris on Noah's chart. How does it move through the night?
- It drifts away from Polaris toward the south
- It circles around Polaris
- It stays in one spot above Polaris
- It moves just once a year, with Earth's orbit
Pia's pen pal lives in Australia, south of the equator. Why can't the pen pal see Polaris?
- Polaris stops shining over Australia
- Polaris moves south for their summer
- Polaris is below the horizon there
- Earth's orbit hides it there
“not to scale” At position C (March), Ren looks for Pisces at night but cannot find it. Why?

Scorpius Pisces Virgo Orion Sun A (September) B (December) C (March) D (June) viewed from above North Pole - Pisces moved farther from Earth
- Pisces stops shining in March
- Pisces is on the Sun's side, in the daytime sky
- Earth's spin keeps Pisces below the horizon through spring
Bright outdoor lights glow all night near Tala's home, and few stars show. What does the NPS say causes this?
- The stars moved away
- Light pollution from outdoor lights
- The stars themselves are slowly dimming
- Earth's orbit
“not to scale” At position D (June), can Zee see Orion at midnight?
Orbit diagram seen from above the North Pole (not to scale). The Sun is in the center. Earth is drawn at four positions, moving counterclockwise: A (September), B (December), C (March), D (June). Far beyond the orbit: Pisces beyond A, Orion beyond B, Virgo beyond C, Scorpius beyond D. At each position, Earth's night side faces away from the Sun.

Scorpius Pisces Virgo Orion Sun A (September) B (December) C (March) D (June) viewed from above North Pole - Yes: it is high in the south
- No: Orion's stars burned out
- No: Orion is in the daytime sky then
- Yes: Orion shows each midnight of the year
