To estimate how long it will take to travel to six objects in the Hubble Deep Field, we need to determine their distances from Earth. This has been a difficult task for our astronomers. At this time we only have distance information for a few of the objects. From those few, we have selected six possible destinations during our mission.

Your job is to place the six objects in order, from nearest to farthest, according to their relative distances from Earth. Your input will be used to help us plan our travel route and schedule.
