Question

practice 3 drag the definition on the right to match the correct term for star brightness. absolute brightness apparent brightness luminosity how bright a star looks from a standardized distance of 10 parsecs how bright a star looks from earth the total energy output of a star

Explanation:

• Absolute Brightness is defined by measuring a star's brightness from a fixed, standardized distance (10 parsecs) to compare stars fairly regardless of their actual distance from us.
• Apparent Brightness is the brightness of a star as observed directly from our planet Earth, which depends on both the star's actual energy output and its distance from Earth.
• Luminosity refers to the total amount of energy a star emits from its surface over time, its intrinsic energy output.

Answer:

• Absolute Brightness: How bright a star looks from a standardized distance of 10 parsecs
• Apparent Brightness: How bright a star looks from Earth
• Luminosity: The total energy output of a star
