Replacement Suns

jkottke:

From the Russian Space Agency, a video of what the sky would look like if the Sun were replaced by some other stars. It starts off with the binary star system of Alpha Centuri, but watch until the end for Polaris, which has a radius 46 times that of the Sun.

See also the view from Earth of different planets replacing the Moon and imagining Earth with Saturn’s rings.

The night scene with Arcturus is the best.
