The attack/defend scenarios that spawn around them can be fun and they're usually situated with a planet as a backdrop so can just be nice looking locations for screenshots. I've never tried it myself, but you can liberate cargo from them with hatchbreakers too. If they happen to be in a power play system (this one isn't, obviously), they give a reasonable amount of merits if you scan the megaship and then the ship uplink with the data scanner.
The Orion is one of the mega ships that belong to October Consortium that was jumping around various systems before the permit for HIP 87621 was handed out (it probably still follows the same route).
