How long does Deneb have to live?
When thinking about the life of a star, Deneb’s lifespan is relatively short and will only live for a few more million years. Deneb is thought to be about 10 million years old but its exact age is difficult to determine because Deneb is so far away from earth.
Is Deneb bigger than Vega?
The three stars that form the Summer Triangle are among the brightest stars in the sky. They have apparent magnitudes of 0.026 (Vega), 0.76 (Altair), and 1.25 (Deneb).
Is Deneb a giant star?
Deneb is a blue-white supergiant star of spectral type A2 la. Though the star is massive, Deneb also looses much of its mass at around 100.000 times the Sun’s rate of mass loss or equivalent to almost one Earth mass per 500 years.
Who discovered the star Deneb?
Deneb’s variability has been known since the early 20th century. It was discovered by O. J. Lee, an astronomer at Yerkes Observatory, University of Chicago, who published his findings in the Astrophysical Journal in 1910. Notable Alpha Cygni variables include Rigel (Beta Orionis, mag.
