The Cosmic Distance Ladder Module consists of matenal on seven dilleren! distance determination techniques. Four of the techniques have external simulators in addition to the backaround pages. Work through the material for each fechnique belore moving on to the next technique. Note: The Distance Modulus (DM) is not a distance determination technique in itself. The DM is the equation used to calculate distances in many of the techniques. Macar nanourie Guestion Radar ranging can be used to directly determine the distance to a solid obiect like Venus or Mercury, but not a gaseous object like the sun. Do some research and summarize how radar ranging can be used to indirectly determine the distance to the sun. This is how the Earth-Sun distance is most accurately measured, and we must know this distance for the stellar parallax method (and all others) to work, (2 points)
