22
What does elliptical mean?
To go around something.
It's perfect circle.
It's a perfect oval.
Can be either shaped more like an oval or more like a circle
23
What is the definition of the solar system?
100,000-300,000
the star that sustains all life on earth
the planets and all the things that orbit the sun
everything
24
What is an important function of space probes as they travel in space?
to take pictures and send them back to earth
to see if life exists on other planets
to analyze what each planet is made of
to land on planets and report conditions there
25
How many galaxies are there?
about 1 thousand
over 100 billion
about 10 thousand
over 10 million
26
Which sequence shows the development of technology in order?

Why did early astronomers think that galaxies were single stars?
light from galaxies collects into a single beam
Earth is small and galaxies are much larger
galaxies are so far away that they look like a single star
galaxies and stars can only be seen one at a time

Even though we may not be able to see them, how can we know that something exists in space?
astronomers have a "sixth sense" that helps them to know
computers can see things that people can't
they give off x-rays that we can analyze
they were once visible and people recorded it
41
Why are computers so important in understanding our solar system?
all of the information about space is on the internet
you can't do science without a good computer
the only way to get into space is by using computers
without computers we could not analyze data fast enough
