Sun Replaced with Other Stars
This
visualization shows how the sunset could look like to a human observer
if our Sun was replaced by some of the other stars in our galaxy with
different sizes and magnitudes, namely Barnard’s Star, Gliese 581, Tau
Ceti, Kepler-23, Alpha Centauri A, Procyon, Sirius, Pollux, Arcturus and
Aldebaran.
It is just a concept, as liquid water
and the Earth as we know it could not exist in the vicinity of the most
stars in this graphic. Visualizations are based on the absolute
brightness, spectral class and the radius of each star. (Source)
