This is a visualization of what it might be like if the Moon was replaced with some of the other planets at the same distance as our moon

Imagine the tides!
Jupiter would produce some impressive tides.
We would probably be tidally locked meaning there wouldn’t be a moving tide.
Freaky.
I could picture the oceans washing over the much of the rest of the planet
Surfing would be awesome
The earth would be a moon of Jupiter not the other way around.
Now that’s cool!
What would it look like? It wouldn't look like anything because all life on Earth would be wiped out if even a planet the size of Mars were in place of our moon.
The gravitational forces would throw our orbit around the Sun so out of whack that we'd be thrown out of that Goldilocks zone very quickly.
And Jupiter? Ha! The radioactivity it spews would make life on the surface impossible.
The moon at ISS distance animation is my favorite of the two. What a solar eclipse!
.....especially with your Venus hanging about
What if they replaced the moon with say, mars, but increased mars’s distance from earth so that the tidal effects would be nearly the same?
that sounds a bit raucous when discussing things as big as Uranus
Saturn is nice. Who doesn’t want a moon with its own rings.
“The earth would be a moon of Jupiter not the other way around.”
Perhaps that is one way of looking at it, but you should realize the Moon/Luna does not orbit around the Earth. The Earth does not orbit around the Moon/Luna. They both orbit around a point in space known as the barycenter, where their gravitational forces equalize. It just so happens the barycenter for the Earth and the Moon/Luna is located near the Earth’s sea level.
Mercury, Mars and Pluto are the only planets which could replace the moon. Venus is nearly as large as the early and has more than 80% of the earth’s mass, so both planets would be circling their common center of gravity (about half-way between them). Jupiter, Saturn, Uranus, and Neptune are all much more massive than the earth so the earth would be a satellite revolving around them.

Well, it wouldn’t take as long to get to Mars if it were as close as the moon.
By definition, the moon does orbit the earth — a smaller body in orbit around a larger body. However, the barycenter is center of mass of the earth and the moon. Libration, or lagrangian, points are points in space where the gravitational forces equalize. Astronomers look for shifts in stars to help them determine if the star has any bodies orbiting it. I don’t think that anyone really says that the associated planets don’t orbit the star because the associated barycenter isn’t colocated with the star’s center of mass.
Make the Donald’s hair stand straight up, those tides would.
