6
Which stars do we always see during the year? Stars...
on the horizon
over the North Pole
In the larger constellations
Inside other galaxies
7
What are galaxies made of?
Dozens of solar systems
Only large clouds of cosmic dust
Millions or Billions of stars
Moons and planets
8
How were constellations originally named and identified?
as people or animals they may have resembled
by their location form Earth's horizon
mathematically, with numbers and coordinates
in groups of very distant, bright or old stars
9
Which best compares the amount of space in the universe to the amount of space galaxies occupy
Galaxies take up about half of the space
Galaxies are less than half but more than a fourth of space
Galaxies take up most of the room in space
Galaxies take up an extremely small amount of space
10
What is the movement of Earth on its axis called?
Rotation
Precession
Phases
Revolution
11
Why did early astronomers think that galaxies were single stars
Earth is small and galaxies are much larger
Light from galaxies collects into a single beam
Galaxies are so far away they look like single stars
Galaxies are made of stars that you can see one at a time
12
What describes an asteroid?
Small body made of rock and metal, orbits the sun
gaseous tail
small body made of ice and rock
small rock or particle of debris
13
Why is it difficult to travel to Alpha Centauri, four light years away
We are not sure exactly where it is
There may be no planets near it
It is very bright and hot
It is very far away
14
Compared to our galaxy, how big is our solar system?
The solar system is extremely tiny
about one-third of the galaxy
The solar system is about one-tenth of the galaxy
over one half of the galaxy
15
What are galaxies made of
moon and planets
two stars orbiting each other
about one hundred stars
many millions of stars
16
Why is the moon visible to us?
It reflects light from the sun
It produces light through combustion
It has an aura
It produces light through fusion
17
If Mercury is 35.98 million miles from the sun, how many astronomical miles (AU) is that?
Between 1 and 2 AUs
Less than 1 AU
1 AU
More than 2 AUs
18
Which correctly ranks astronomical objects by size, starting with the smallest?
Sun, solar system, Earth, universe, galaxy
Solar System, Earth, sun, universe, galaxy
Universe, galaxy, solar system, Earth, sun
Earth sun, solar system, galaxy, universe
19
What describes a comet?
Made of rock and metal, orbits sun
smaller than an anteroid
Made of ice and rock, gaseous tail (dirty snowball)
Rock or particle of debris
20
Why is the North Star a reliable choice for navigation
The north star seems to be unmoving as we see it from earth
The North Star is only visible during spring
The north star moves with the crew and the ship
The north star is located at the celestial south pole
21
Why does the moon appear to move across the sky during the night?
The moon is extremely far away
Earth is rotating on its axis
All objects in space are moving
The moon travels around Earth every day
22
Why does the sun seem brighter than the star Alpha Centauri?
Light from Alpha Centauri is blocked by the moon
Alpha Centauri is a larger star than the sun
The sun is much closer to Earth than Alpha Centauri
The sun generates energy through the process of fusion
23
How were constellations originally named and identified?
By their location from Earth's horizon
As people or animals they may have looked like
Mathematically, with numbers and coordinates
In groups of very distant, bright or old stars
24
As Earth travels in its --, different constellations are visible at different times of the year
galaxy
orbit
star cluster
atmosphere
25
Astronomers once thought that galaxies were single stars. Why?
Galaxies are made of stars and you can only see each one
Light from galaxies collects into a single beam
Galaxies are so far away they look like a single star.
Earth is small and galaxies are much larger

Why are distances in space often measured in light years?
Scientists always use metric units like light years
The light year is a commonly used unit of measure
Distances in space are so great that a large unit is needed
Light years are easy to measure and understand
