There's a moon in the sky, it's called Neptune

Aldebaran looks stressful.

Seeing Venus so close, I'm reminded that it is our sister planet. I mourn for it. I pains me that we cannot go.
Orbiting Neptune makes it seem more alien; something about the completeness of its disk makes it feel inaccessible, foreboding. Jupiter, though, feels like being in the protection of a giant, swung in circles by its cradling arms.
I'd love to live around a huge, dim star, where sunrise and sunset each last as long as the rest of the day.

I don't think humans could ever colonize a moon of Saturn. We'd never get anything done, just stare at the night sky all the time.

If you think that Aldebaran looks stressful, Betelgeuse would be even worse:
[Betelgeuse] is one of the largest and most luminous observable stars. If Betelgeuse were at the center of the Solar System, its surface would extend past the asteroid belt, possibly to the orbit of Jupiter and beyond, wholly engulfing Mercury, Venus, Earth and Mars.posted by Johnny Assay at 6:53 AM on July 12, 2015 [1 favorite]

I wonder if the people who assembled the piece at least briefly considered an entirely red screen for the Betelgeuse shot.

There are a few videos by "yeti dynamics" that explore the idea of other planets orbiting earth: Saturn, various planets at night, and during day time>

If Earth were orbiting Jupiter at that distance every living thing would be fried by radiation and the whole surface would be one big volcanic caldera due to the tidal stresses, like Io.
While it's a cute visualization exercise the replacements oscillate wildly between teneble and ridiculous, where a body the size of Earth could not possibly have formed or been migrated or where the surface would be a molten radioactive hell.

I can't seem to find it anywhere on the internet nor the Wayback Machine, but I remember a See Mike Draw cartoon that basically went like this:
1. Anthropomorphic Earth and Sun stare into each other's eyes & profess mutual desire.
2. Earth and Sun embrace and Kiss.
3. Earth's surface at human scale: conflagration, immolation, fiery apocalypse.

In the moon shots the perspective is off, notably for Saturn. This looks like they dropped in a telephoto shot, rather than the relatively close-up shot that's needed to get the right perspective and angle of view. If it were that close (and with the tilt depicted) you would see a lot more of the near side of the rings, because they would span so much of the distance.

The same thing occurred to me, George_Spiggott; being right is hard.

You can also have fun asking what if things in the sky were brighter (or our eyes were more sensitive). Like, the Andromeda galaxy, M31, is several full moons across. It's just dim. Several other galaxies appear have an angular size at least as large as the moon.

I made a few pictures similar to the ones where the moon is replaced with Jupiter or Saturn. The perspective freaked me out so much that I just saved them in a folder and never looked at them again. Having something so massive just hanging in the sky would terrify me.

Well properly speaking if something that massive is at that distance it's more like we would be hanging in its sky. Astronauts in Low Earth Orbit don't seem to develop an oppressive sense that the Earth is going to crush them.

There's a chapter in What If the Earth Had Two Moons about what it would be like to live on an Earth-like moon in orbit around a Neptune-like planet. Pretty interesting! Of the various moon-replacements in the link, I thought Neptune was far and away the one I'd choose to look up and see.

Raise your hand if you heard a wistful Star Wars theme in your mind when you looked at Kepler 35.

This video from Roscosmos seems to take perspective into account.

My favourite Yeti video: If the Moon Were at the Same Distance as the ISS (assume a significant reduction in density). My three-year-old son couldn't get enough of this stuff for a while.

Very nice. The "Saturn" link from smcameron above does as well, in a stunning and disturbingly dynamic way. (Don't be put off by the hilariously '80s graphics in the title card, or the 2D opening diagram animation; it gets good around :45 and really fun by 3:00.)

This describes Fairbanks AK (and I suppose other far north/south regions) around the winter solstice pretty well, actually. First the sun rises for a couple of hours, then it sets for a couple of hours.

I like to imagine this is just Orion performing an epic guitar solo throughout space and time.
