Bad Astronomy: Proxima b




Proxima Centauri Radius: 695,700 km × 0.141 = 98,093.7 km
Proxima Centauri b Radius: 6,384 km
Proxima Centauri is 15.365 Proxima Centauri b Radii in radius. This is approximately what we see in the hubble image (without counting pixels of the star).

Its distance is 7,500,000 km (587 planet diametres) from the star centre which is ten times what it looks like so we are looking at a triangle and its our direction from Proxima Centauri at a gradient of 10:1 at about an angle of 340 degrees clockwise from vertical. I assume that a perpetually star-facing south pole means it is tidally locked.

It Qualifies as Thick cloud so its in the 0.8 Albedo putting its temperature at -167 K (-106 degrees Celsius). It well inside the ice line so I assume the Rings are Water or dust trying to turn into moons?
Did get that one day orbit object in the graph data so a potential moon with water?

Here is to better astronomy toys in the future and a little watery moon named Phet Rok.

Update: some explanatory art

 Its either this side of the star and we can see only part of the ring, thanks to solar noise.
Or its behind the star and we are getting an image projection of what is visible.
