🔍 Key Concepts

• Apparent magnitude scale used in astronomy • How larger vs smaller magnitude numbers relate to brightness • Typical limit of human vision under dark, clear skies with no light pollution

💭 Think About

• Is a higher magnitude number a brighter or a dimmer star on the apparent magnitude scale? • Think about how many stars you can see in a truly dark, rural sky—does the eye reach a relatively small or fairly large magnitude number? • Which of the options represents the faintest (highest number) star still visible without optical aid?

✅ Before You Answer

• Remember that on the magnitude scale, each step is a fixed change in brightness, and the scale is backwards (smaller or negative numbers are brighter). • Identify which choice has the largest magnitude number, since the question asks for the dimmest star that can still be seen. • Mentally compare bright stars (like Sirius or Vega) to the general background of the Milky Way to gauge what unaided human vision can reach in ideal conditions.
