What is the distance of Altair from Earth?

• A. 4.5 light years
• B. 16.7 light years
• C. 36.7 light years
• D. 10 light years

Answer: (B)

Altair is approximately 16.7 light years away from Earth. This distance places Altair, a prominent star in the constellation Aquila, among the nearest stars to our planet. It is classified as an A-type main-sequence star, which is indicative of its relatively hot and luminous characteristics compared to other stars. Understanding the distance of celestial objects like Altair is crucial for various astronomical studies, including those related to stellar evolution and the galactic neighborhood. The values for the other distances mentioned reflect either miscalculations or a misunderstanding of stellar distances, as Altair is specifically cataloged at around 16.7 light years, which is supported by astrometric measurements and parallax observations.
