Aurora on Proxima Centauri B

Proxima Centauri has been in the media a lot lately. This tiny red dwarf - only 1/7 the diameter of the Sun - is the closest star outside the Solar System, at 4.25 light-years.
What's so special about it? Well, it's got a planet in orbit around it dubbed, unceremoniously, Proxima b. The media has been calling this an 'Earth-like' planet but that's a misnomer. What they mean is terrestrial - it's made of rocky and metal, like the Earth, not a fluid like say Jupiter. But it could easily be as airless as Mercury or as sterile and stifling as Venus. Personally, I think it's likely to have some sort of atmosphere. It's heavier and bigger than the Earth, so it has the gravity to retain heavy gases, unlike Mercury and Mars. It also orbits in its star's habitable zone - theoretically, a region surrounding a star within which liquid water can exist on an the surface of orbiting body.
Here’s my take on it. I've included an atmosphere but no water. To the left of Proxima is Alpha Centauri, a binary consisting of two Sun-like stars.
Proxima is a flare star - it's highly magnetic and spews out streams of charged particles. If the world has its own magnetic field (like Earth) and an atmosphere, this would be a fantastic place to go aurora spotting!

This video is so beautiful and interesting that I am sorry that it is so short. Proxima lies in the ecosphere of the system so it could be tempered in the always illuminated hemisphere and frozen in the always dark hemisphere; using Space Engine I tried to create a planet of this type, divided into 2, the resulting environment is not very different from the one you created, apart from the presence of water which is possible.

Thanks again. I'm glad you like my work!

Excellent! And, as I would expect, a very credible visualisation!

Nice and very interesting video as always. Mountains are sort of "jumping" from 0:41, was that intended? Question: where can I buy a NEW copy of your book "The Expanding Universe - a beginners guide to the big bang and beyond"? On Amazon it is listed as a used book for 0,15$ by some random seller which does not sound realistic at all. P.S. I already have your book "The Illustrated Atlas of the Universe" which is awesome and I like it very much.
