I wonder if this can simulate the view of the sky from a planet's surface, given an interesting planetary system. I'd like to simulate what the day/night phases look like on the namesake planet of Kim Stanley Robinson's "Aurora" that I have just read... the moon orbiting a super-earth itself orbiting Tau Ceti.

Or for that matter, the planet in some science fiction novel (can't remember the name) that orbits in some weird trinary (or higher) system and only has nightfall once a century (triggering a social breakdown everytime it occurs).

What you want is Space Engine [en.spaceengine.org/]. Also a sandbox. Allows you to fly from star to star, galaxy to galaxy, with billions of planets, nebulae, black holes, clusters, etc. to choose from.

As an example: tonight I had a few minutes to kill so I visited a small desert (Mars-like) planet with a thin ring located in an orbit around dual stars located in a globular cluster. By day, one sun rose and then another. Absolutely scorching the broad plains and distant mountains. Night eventually fell and the sky was burning with the crimson light of the thousands of red giants in the cluster and the brilliant white light of the galactic center. The light was broken slightly by the silhouette of the rings' arc overhead. Was quite beautiful.

Nicely spoke! You should write sci-fi

I think you are talking about Nightfall by Asimov. https://en.wikipedia.org/wiki/Nightfall_(Asimov_short_story_...

Yes that's the one.

You can, in fact, place yourself on the surface of a planet in this game to see what hell you hath wrought above.
