Brightness vs. Reality: Apparent vs Absolute Magnitude Quiz

Why do some dim stars look brighter than giants? A star might look like a beacon simply because it's close, while a cosmic powerhouse looks like a speck because it's far away. This apparent vs absolute magnitude quiz...

Questions: 20 | Attempts: 10 | Last updated: Feb 20, 2026

Sample Question 1
What does "apparent magnitude" measure?

The actual energy output of a star

How bright a star appears from Earth

The temperature of the star's surface

The distance of the star from the Sun

The chemical composition of the star

Sample Question 2
A star with a magnitude of -1.5 is brighter than a star with a magnitude of +2.0.

True

False

Sample Question 3
At what standard distance is "absolute magnitude" calculated?

1 astronomical unit (AU)

10 light-years

10 parsecs

100 parsecs

1 million miles
