What does the color of Altair mean?
white
Spreading light into a rainbow Full Story Below Altair is a bright star visible in the summer night sky in the northern hemisphere. Altair’s spectrum shows that its blueish-white light is actually a mixture of colors of different brightness.
Is Altair a white dwarf?
Altair is an A-type main-sequence star that has an apparent magnitude of 0.76. Its spectral type is A7 V – thus it is a white main-sequence dwarf.
What will Altair become?
Altair has the New Suspected Variable designation NSV 24910 and is unusually bright for its spectral type and so may be becoming a subgiant star that is beginning to evolve off the main sequence, as it begins to fuse the increasing amounts of helium “ash” mixed with hydrogen at its core.
What is the life cycle of Altair?
The black dwarf is the end of a star’s life cycle. Unlike our sun, Altair will only live to 2 billion years old. A White Dwarf is a kind of emission nebula consisting of an expanding glowing shell of ionized gas ejected from old red giant stars late in their lives. These are some examples of Planetary Nebula.
Is Altair a blue star?

How long will Altair star last?
about two billion years
Altair is about twice as massive as the Sun, so it will live only about two billion years versus the Sun’s 10 billion. Despite its size, Altair appears to turn on its axis once every 10 hours, compared to about four weeks for the Sun.
Is Altair a binary star?
Altair is the 12th brightest star in the night sky and is the brightest star in Aquila based on the Hipparcos 2007 apparent magnitude. The star can be seen with the naked eye, that is, you don’t need a telescope/binoculars to see it. Altair is a Binary or Multiple star system.
Who discovered Altair star?
In 2007, University of Michigan astronomers combined light from four widely separated telescopes to produce the first picture (above) showing surface details on Altair. The researchers, led by John Monnier of U-M, used optical interferometry to get this image.
What type of star is altaltair?
Altair is a white main sequence dwarf star of spectral and luminosity type A7 V-IVn.
Can you see Altair with a telescope?
With a telescope, an optical companion may be visible. (See Akira Fujii’s color photo of Altair — brightest bluish star at the top center of photo.) evolution and death. Altair is a white main sequence dwarf star of spectral and luminosity type A7 V-IVn.
How many light years away is Altair from Earth?
At a distance of 16.73 light years, Altair is one of the nearest stars to Earth visible to the unaided eye. Altair is one of the vertices of the Summer Triangle, a prominent asterism also formed by the bright stars Vega in the constellation Lyra and Deneb in Cygnus.
Is Altair brighter than Deneb?
Altair is the nearest of the three stars. It is also the coolest and least luminous. It appears brighter than Deneb, but not quite as bright as Vega. Altair is also part of the Shaft of Aquila, a line of stars that makes it easy to identify the star in the night sky in good conditions.
