🔍 Key Concepts

• Apparent magnitude scale and what the numbers mean • Difference between negative and positive magnitudes • What magnitude actually measures: brightness as seen from Earth, not physical size

💭 Think About

• On the magnitude scale, does a larger number mean brighter or dimmer? Think about which direction the scale goes. • How do negative magnitudes compare in brightness to positive magnitudes? • If two stars have magnitudes -0.9 and +0.1, which one would appear brighter to an observer on Earth?

✅ Before You Answer

• Recall that smaller (more negative) magnitude values correspond to brighter objects. • Confirm that magnitude is a measure of brightness as seen from Earth, not the star’s physical diameter. • Compare the given magnitudes and identify which value represents the greatest brightness on this scale.
