$100 Question from AU
What is an astronomical unit?
$100 Answer from AU
An astronomical unit is a unit
used to measure distance within
the solar system.
$200 Question from AU
How many kilometres is an
astronomical unit equal to?
$200 Answer from AU
An astronomical unit is equal to
150 million kilometres.
$300 Question from AU
What are astronomical units
based on?
$300 Answer from AU
Astronomical units are based on
the distance between the Earth
and the Sun.
$400 Question from AU
Why aren’t astronomical units used
to measure distances outside of the
solar system?
$400 Answer from AU
The rest of the universe is so vast
that astronomical units are too
small; light-years are used instead.
$500 Question from AU

in the universe, with a
human being equal to 1,
what would the observable
universe be equal to?
$500 Answer from AU
10 to the power of 26

when using triangulation?
$200 Answer from Indirect
Measurement
There are five main steps
$300 Question from Indirect
Measurement
During parallax, does the object or the
obsever change positions?
$300 Answer from Indirect
Measurement
The observer.
$400 Question from Indirect
Measurement
Within how many light-years
can parallax and triangulation
be used to measure distances
accurately?
$400 Answer from Indirect
Measurement
Within approximately 500 lightyears away.
$500 Question from Indirect
Measurement
How many angles are used to
measure distances when using
triangulation?

Measurement
Two, angle A and angle B
$100 Question from Vocabulary
What is the definition of a light-year?
$100 Answer from Vocabulary
A light-year is how much distance
light can travel in one year.
$200 Question from Vocabulary
What is the definition of triangulation?
$200 Answer from Vocabulary
Triangulation is a method of indirect
measurement that uses a scale
diagram of a triangle to measure
unreachable distances to stars
$300 Question from Vocabulary
What is parallax?
$300 Answer from Vocabulary
Parallax is the apparent shift of an
object due to a change of the
position of the viewer.
$400 Question from Vocabulary
Where does the word parallax
come from?
$400 Answer from Vocabulary
The Greek word παράλλαξις
(parallaxis), meaning alteration.
$500 Question from Vocabulary
What do parallax and triangulation have
in common?
$500 Answer from Vocabulary
They are both methods of indirect
measurement.

Are light-years used to measure time,
speed, or distance?
$100 Answer from light-years
Distance
$200 Question from light-years
Are light-years used to measure
distances greater or smaller than what
AUs are used to measure?
$200 Answer from light-years
Greater
