Danula II

From Hidden Frontier

Danula II was the host of the Starfleet Academy marathon when Cadet Jean-Luc Picard won the race as a freshman. (TNG - "The Best of Both Worlds, Part II")

It is also the location of a Starfleet science facility where Ensign Artim Ibanya was offered a position when his assignment to the team studying the metaphasic rings of Ba'ku came to an end. He turned down the assignment in lieu of an assignment to the USS Excelsior. (HF 2.06 - "To The Stars")
