The brightness of a star as seen from Earth is its 

• apparent brightness.

• absolute brightness.

• parallax.

• reflective brightness.

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

• further away

• cooler in temperature

• very close

• batteries are dying

The absolute brightness of a star depends on its

• distance and temperature.

• size and temperature.

• color and temperature.

• distance and color.
