supported by the information in the
diagram?

proportionate to the brightness of
the supergiant stars

between the planet’s distance from
the Sun and its orbital velocity.
Question 9
If a person is sensitive about their
weight, why would they refuse the
opportunity to live on Saturn?

What reason do scientist give for using
light years to measure distances in
space?
A. The speed of light is easier to
measure than the speed of sound.
B. Using kilometers to measure
distances in space results in large

system would result in using
fractions of light years instead of
whole numbers.
