More Altair information ...
Altair is a white A7V main sequence star. The star is about 1.6 times the diameter of the sun.
The spectral type implies an effective temperature of 8100 K, a luminosity about 9 times that of the sun, and a mass almost twice that of the sun.
Altair will be like an older vehicle, the Lunar Module. This spacecraft was used in the 1960s and 1970s during the Apollo program. Astronauts used the Lunar Module to land on the moon six times. Like Altair, the Lunar Module had two stages.

The brightest star in the Aquila constellation is [435] Altair or alpha Aquilae, a type-A main sequence star. Its name derives from the Arabic phrase "an-nasr attair," meaning "the flying eagle." At 16.
The brightest stars"Vega, Deneb, and Altair"form a conspicuous triangle high above the constellations Sagittarius and Capricornus, which are low on the southern horizon. In the winter sky, however, these stars are replaced, as shown in Figure 1.
An ancient constellation whose bright star Altair marks one third of the asterism known as the "Summer Triangle". Aquila is the eagle that was the symbol of the ancient god Zeus.
A significant number of stars in the sky, such as Aldebaran and Altair, and astronomical terms such as alhidade, azimuth, and almucantar, are still today recognized with their Arabic names.
History
Pre-Islamic Arabs had no scientific astronomy.
European researcher Michael Rappenglueck, however, suggests that it is a map of three particular stars — Vega, Deneb, Altair — that astronomers today refer to the Summer Triangle.
Aquila's Bayer stars are generally third and fourth magnitude, except Altair (alpha Aql), the twelfth brightest star. Altair spins very rapidly, completing one revolution every 6.5 hours, which deforms the star.
Altair (α Aql), Alshain (β Aql), Anser (α Vul), Deneb Dulfim (ε Del), Deneb el Okab (ε Aql), Deneb el Okab (ζ Aql), Kitalpha (α Equ), Rotanev (β Del), Sham (α Sge), Sualocin (α Del).
These are Altair, Deneb, and Vega. These form a bright triangle, with the Southernmost star (farthest from the other two) being Altair, the brightest one (to the West) being Vega, and the one to the East being Deneb.

Ancient Hindus saw it as a triangle, or as the three-cornered nut of the aquatic plant Cringata. Vega, along with Deneb Adige in the Swan, and Altair in the Eagle, forms the Great Summer Triangle.
This faint planetary can be found about 5° W of Altair and 2° NNW of m Aquilae (see finder chart below). A bright star-like planetary nebula NGC6803 is located almost 1° further North.

SUMMER TRIANGLE
The Summer Triangle is a group of three bright stars (Deneb, Vega, and Altair) which are visible during the summer in the Northern Hemisphere. The Summer Triangle is not a constellation, but an asterism.
Vega, the brightest star in the constellation Lyra is easy to find as part of the triangle with Deneb and Altair, the brightest stars in Cygnus and Aquila. This trio is referred to as the Summer Triangle.
