(yes yes I realize that the environmental conditions would vary greatly with different stars at the same distance, still an interesting visualization)

(36,263 posts)and it turns out Albireo A is actually a close double, with an orbital period of ~213 years.
A planet around either A or B would see the other as a bright star, since they are separated by a very large distance (orbital period ~100,000 y). Not sure A would have any long-term stable planetary orbits. Both A & B are much more massive than the sun, so such a large orbital period indicates a really large distance (period ~ M-1/2) -- many times the distance from Sol to Pluto (which has an orbital period of ~248 y, and from which the Sun appears as a particularly bright star).

(16,423 posts)You have a sun and an Earth-like planet.
To get points, you add more planets, but beware that none get flung out in swing-by maneuvers.

And they seem to have their fair share of planets.
Most of our nearest neighbors turn out to be red dwarfs -- but most are not visible to the unaided eye !

I can't help but notice they left out Betelgeuse

(904 posts)For fun, I'd like to see similar pics for these stars in the afternoon or morning, and maybe for a planet in the Goldilocks Zone as well... (As you said, the last few stars likely wouldn't have liquid water under those conditions.)
