Apparent (magnitude) brightness is affected by a star's distance from Earth.

• False
• True

Which property of a star is the brightness of a star at a standard distance?

• Apparent (magnitude) brightness
• Absolute (magnitude) brightness
• Luminosity
• Size of the star

Star R and S both have the same luminosity of 100, if Star S is 10 ly farther from Earth which star has the highest apparent magnitude?

• Star R
• Star S
• Both Star S and R

Star Z and W both have the same luminosity of 100 lux, if Star Z is 10 ly closer to Earth which star has the highest apparent magnitude?

• Star W
• Star Z
• Both Star Z and W
