Based on your answers to the previous questions, what is the
relationship between brightness and apparent magnitude?
Question 4 options:
brighter stars have smaller apparent magnitudes
there is no relationship between brightness and apparent
magnitude
brighter stars have larger apparent magnitudes
Would a star of apparent magnitude -2.0 be brighter than Sirius
or fainter?
Question 5 options:
fainter than Sirius
brighter than Sirius.
While apparent magnitude measures how bright a star appears to
us on Earth, absolute magnitude measures the total energy a star
radiates. Apparent magnitude depends on absolute magnitude and the
distance between the Earth and the star.
How would the brightness of a star, as viewed from Earth,
change if the star is moved further away from Earth?
Question 6 options:
The brightness would stay the same.
The brightness would increase.
The brightness would decrease.
How would the apparent magnitude of this star be
affected?
Question 7 options:
The apparent magnitude would decrease.
The apparent magnitude would increase.
The apparent magnitude would stay the same.
How would the absolute magnitude of this same star change
as it was moved away from Earth?
Question 8 options:
The absolute magnitude would stay the same.
The absolute magnitude would decrease.
The absolute magnitude would increase.
