Question

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.
