The distance that light travels in one year is called a light-year. What is this distance (1 light-year) expressed in kilometers? Exercise: One parsec is a unit of distance equal to roughly 3.25 light-years. The prefix Mega means "million." A star system 24 Mpc (Megaparsec) away from us in the direction of Orion is home to a hostile alien civilization intent on enslaving humans and forcing us to manufacture pizza sauce for their pleasure. What is the distance to these rapacious aliens in kilometers? Use your answer from the previous exercise.
