Let's talk a little about the new earth-like planet planet that's been discovered recently, right next door.

From what I've seen & heard, it's orbiting Proxima Centauri & is so far from Alpha Centauri A&B that they would appear as a single star to an observer in orbit around the planet.
I must say I was surprised to see such a planet discovered around a red dwarf but, assuming that it is in fact 'earth-like', I wonder what it would be like on the surface.

How would the reddish light affect vision?
How bright would the 'dwarf appear to be to the naked eye from the surface?
What, if any, would be the effect of the 'redness?' (a more infra-red compared to Sol) of the of the dwarf's radiation  be?
Would it possible to get a 'sunburn'?
Also, as I recall, Proxima actually orbits A&B.
How far away is that orbit compared to our solar system?
Is it farther away than Uranus?

Any & all speculation would be welcome.

TIA,
