Altair III
Type:	Planet
Location:	Altair system

Altair III was the third planet of the Altair system.

In the early 2360s, when the USS Hood visited this system, Lieutenant Commander William T. Riker stopped Captain Robert DeSoto from transporting to the surface of Altair III with an away team, because he deemed the action as too dangerous, inappropriate for a commanding officer.
