you would probably hit the point where gravity is breakeven and so you'd float over to Saturn.

Saturn rings messing with the earth's atmosphere, dropping stuff on earth, that sort of thing. And I wondered what would happen to our moon.

8. The Earth would orbit Saturn, and probably become tide-locked (the same side always faces Saturn).

Kinda like the Moon is tide-locked.

In the photo where Venus replaces the Moon, you would get Venus and the Earth orbiting a common middle point, probably both tide-locked, and Venus shining so bright that you could read by it at night, if you were on the side of the Earth that could see Venus.

With Jupiter at the distance of the Moon, the radiation around Jupiter might fry us, and the tidal forces might cause as much volcanism as on Io.

"you would get Venus and the Earth orbiting a common middle point"

In actual point of fact, Earth and the Moon do currently orbit around a common central point. That point is much closer to the center of Earth than the Moon's center, but the Moon does move the Earth slightly.

More mind bogglingly, Earth and the Sun orbit around a common center point. That center is probably well within the Sun, but...

12. Right. That's one way they detect exoplanets, by the wobble of the star around that point.

Venus and Earth are so close in size, that point would be very close to right in the middle between them. A skosh closer to the Earth.

4. I'd like to see photos of planets from the distance of their own moons, moon views.

They exist, so needed would be sorting and labeling them.

The mean distance to the moon is 238,600.774 miles.

Fact 1: If you took all the passenger vehicles in the United States (254.5 million) and placed them bumper to bumper, they would stretch over twice the distance to the moon.

Fact 2: If you did that, some idiot at the back in a BMW would pull out and try to pass.
