• Astronomical units

• Light seconds

• Light years

What's wrong with Han Solo's claim of making "the Kessel Run in less than 12 parsecs"

• Even the Millennium Falcon can't travel that fast

• He should have used 'astronomical units'

• Parsec is a measure of distance, not time

• He should have used 'light seconds'

• AUs

• Light seconds

• Light minutes
