Steve wants to calculate the distance between Earth and several stars. He hypothesizes that the Sun is the closest star because it is the brightest. He wants to design an experiment that will measure the distance to the Sun and other stars in kilometers. Why is Steve's idea for measuring distance flawed?

• The distance will be too far to measure in kilometers. He will have to measure the distance in light years.

• The distance can be measured accurately in kilometers using standard tools.

• Measuring in kilometers is more accurate than using light years.

• Kilometers are only used for measuring distances within the Earth.
