With Stars in a Sphere One Light Day Up, How Big is Betelgeuse?


As some readers of this blog might know, and of other blogs of mine as well, I am Geocentric.

Ergo, I don't believe "parallax" really is parallactically produced by "earth's own movement around the sun".

Ergo, I don't believe we have very good reasons for the distances given to stars, nor for their sizes.

The size of a star is a function of apparent size and distance. The apparent size is a direct given, it can be observed at least by comparison to other apparent sizes. So, it cannot be disputed.

Now, Betelgeuse is supposed to be ∼643 light years away (other measures or alternative readings of measures exist), and I'll suppose instead Betelgeuse is just one light day up. If its parallax is no parallax, there is no parallax to contradict it.

Its radius is supposed to be 955 to 1200 times that of the Sun in French wiki (English saying between 887 and 955).

I'll take 1200 times as the greatest. It probably has something to do with the greatest version of its distance, 643 light years.

643 light years * 365.25 light days / light year = 234 855.75 light days.

This means the radius of 1200 solar radiuses must be divided by 234 855.75 to get the radius if it is one light day up.

We get 0.005 109 519 353 901 3 solar radiuses. So, how long is the radius of the Sun (since its distance is undisputed, its radius is undisputed too)?

696 342 km * 0.005 109 519 353 901 3 = 3 557.972 925 934 339.

The radius of Betelgeuse would be around the distance of flight between Paris and Belushya Guba, Arkhangelsk Oblast, Russia. The diameter would be a bit larger than half the diameter of earth.

Biggest object I took a look at through this kind of calculation so far ...
