With the bright stars Deneb and Vega, Altair (Arabic for “flying eagle”) forms the prominent asterism of the Summer Triangle. Based on the star's spectral type of A7IV-V , Altair's colour and type is blue - white subgiant star. The time it will take to travel to this star is dependent on how fast you are going. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. The number of A.U. It’s possible that Altair has begun to utilize helium in the core, and therefore could be on the way towards becoming a subgiant star. U.G. (TNG episode: "Yesterday's Enterprise", TNG reference: The Continuing Mission) Ruins on the surface of at least one world in this system indicated that the Preservers once inhabited this planet whilst certain locations show evidence that the Vegan Tyranny also had a connection to Altair.
