Imagine traveling to six objects in the HDF. To estimate how long it will take to travel to each one, we need to determine their distances from Earth. This has been a difficult task for astronomers. At this time, they only have distance information for a few of the objects. From those few, we have selected six possible destinations.
Your job is to place the six objects in order, from nearest to farthest, according to their relative distances from Earth.
