The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it.

C)The star's distance. B)The star's size.

DENEB STAR LIFE CYCLE. The star forms one of the vertices of the Summer Triangle asterism, and marks out the “head” of the Northern Cross. A)Barnard's star B)Procyon C)Alpha Centauri D)Rigel Deneb is a Binary or Multiple star system. 1. The star Deneb in the constellation Cygnus is one of the most distant stars you’ll ever see with your eye alone. What is the life cycle of deneb? Hot, massive blue giant stars spend far less time on the main sequence compared to small yellow stars like our sun - approximately 10 million years as opposed to 10 billion.

D)The star's shape. Deneb, a Supergiant 200,000 Times Brighter Than the Sun Alpha Cygni, better known as Deneb, is a first magnitude star, the nineteenth in order of brightness among those visible to … Nebula, Black hole, Main sequence, Nebula, Neutron star, protostar, Red Giant, Super giant, super nova, white dwarf, nova, low mass star <<<-- only use the stages that pertain to DENEB.

Deneb is the 19th brightest star in the night sky and is the brightest star in Cygnus based on the Hipparcos 2007 apparent magnitude. This makes Deneb one of the largest A-type stars known.

Please explain all of the stages of the stars life cycle. 27.Which factor does not affect a star's absolute magnitude (Luminosity)? D)changing from a giant star to a white dwarf star 26.The Sun is inferred to spend the greatest amount of time in its life cycle A)The star's temperature. Deneb’s luminosity and temperature, as well as its small angular diameter of 0.002 arcseconds give a radius about 203 times that of the Sun. Deneb (Alpha Cygni) is the most luminous star in the constellation Cygnus, and with an apparent magnitude of +1.25, it is the 19th most luminous star in the entire night sky. Before evolving into a supergiant, Deneb was a blue O-type main sequence star with about 23 solar masses.

This pressure continues to increase as the nebula gets smaller and the temperature rises, leading to the next stage of a star's life cycle. This heat then causes an increase in pressure which pushes against the gravity slowing the collapse of the star.

That’s because it’s one of our Milky Way galaxy’s most luminous stars.
