It is an A-type star 16.6 light-years from Earth. It lies only 16.7 light years from Earth. Because of its vastness, space brings a whole new dimension to measuring distances. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Its variable/pulsating period lasts for 7.9 days (variability). While real stars distances are highly accurate as they are based on the newest data available (from the 1990s HIPPARCOS satellite survey), somehow even revising older information (e.g. Altair is just 16.7 light-years from Earth, making it one of the closest naked-eye stars visible in the sky. It lies at a distance of approximately 16 light years from Earth, and its color is pale yellow. Altair, or Alpha Aquilae, is the brightest star in the constellation Aquila, the Eagle.

(a) What is the distance to Altair in kilometers? Altair is the 12th brightest star in the night sky and is the brightest star in Aquila based on the Hipparcos 2007 apparent magnitude. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 1.92. It should not be taken as though the star is moving closer or further away from us. The items in red are values that I've calculated so they could well be wrong. First, Altair rotates rapidly. The Galacto-Centric Distance is the distance from the star to the Centre of the Galaxy which is Sagittarius A*. Based on the star's spectral type of A7IV-V , Altair's colour and type is blue - white subgiant star. It lies at an approximate distance of 1,260 light years from Earth in the constellation Orion.
