Wait, what? The
Anosova (1994) article? That article makes the claim that Proxima is almost certainly in a hyperbolic orbit around Alpha AB, which I understand was refuted several years ago (yeah, Kervella 2017), producing an eccentricity of 0.5(+0.08 -0.09). Do we still accept the 1994 conclusion?
1030:
The group they propose includes the Alpha
Centauri system, so the nature of Proxima Centauri's orbit does not necessarily negate the proposed co-moving hypothesis. That being said, I couldn't find any follow-up studies based on more accurate astrometric data so it probably is not widely accepted.

seems to be wrong, as the planet "Proxima
Centauri d" is marked as uncertain ("?"), whereas according to the text and exoplanet.eu it is the outermost planet Proxima Centauri c which is disputed.

The answer should be Sun...Sun is the nearest star with a distance of 93,000,000 miles from earth. while proxima century lies at a distance of around 25,300,000,000,000 miles from the earth.

Thank you for your investigation. I restored the paragraph in the article using the original cite, but changed the URL to a bibcode. Hopefully that will protect it from future bot changes.

That's because our understanding of the system has changed since the image was made. It could be updated, although I can't find the label for planet d in the SVG source code.
