• The sun is the largest star

• The sun farther away that other stars

• The sun is the oldest star we can see

• The sun is the closest star to Earth

Most distances in space and to stars outside of our solar system are measured using.....

Parallax is used to determine a star’s

• distance from Earth.
• temperature.
• composition.
• brightness.

The absolute brightness of a star depends on its

• distance and temperature.
• size and temperature.
• color and temperature.
• distance and color.

The Hertzsprung-Russell diagram shows that main-sequence stars

• are mostly hot and dim.
• are mostly cool and bright.
• increase in brightness as they increase in temperature.
• decrease in brightness as they increase in temperature.

The brightness the star would have if it were a standard distance from earth.

• Apparent Brightness
• Absolute Brightness
• Brightness
• Candid Brightness

A very bright star can seem to be dimmer because it is 

• further away
• cooler in temperature
• very close
• batteries are dying

The distance that light travels in one year...

• Light year
• Quantumyear
• Stellar-year
• 1 million kilometers
