And why?
I like Jupiter. It’s massive, and looks spectacular with the naked eye. It’s sort of awe-inspiring that it’s so far away, yet so ginormous that it appears so (relatively) big in the night sky. Also, very cool to look at with even a moderate-powered telescope.
I only have experience of living on one, so I’m not sure I’m qualified to answer this question.
So I’ll say Neptune. A most pleasing hue of blue, with the occasional cloud system to spice things up
Uranus is a colour favoured by elderly car buyers, not nice at all.
Saturn is a bit showy, and it’s not even round.
Jupiter is quite pleasing, if a little self-important.
Mars is quite funky, with it’s polar caps, mountainous valleys, and dust storms.
Earth would be my second choice.
Venus is a hell-hole.
Mercury is all beat to hell, I imagine it’s a bit of a dive.
(Oh, and I’ll be the first to nitpick, Pluto should be on the other list.)
Pluto, because it is a planet, damnit!
Yeah, but I was trying to avoid the whiners. Besides, some people really do like it best.
Mars, because it’s the first we’ll visit. (And I don’t know you well enough to love Your Anus.)
Neptune. It’s nice and blue.
I voted for Pluto as a protest to re-instate its status as a planet.
Venus. Because of Space Cat Visits Venus, it went to my top spot as a youth, and it’s never been unseated.
I think moving Venus’s orbit out might be a better investment in terraforming than greenhousing Mars, although I’m basing that on stuff pulled out of my ass.
Uranus. Many a starry night, I’ve explained how once you locate the north star, if you then lean over backwards far enough you can see Uranus.
I should grow up.
Pluto because we all know what its like being unemployed.
Mars is a pretty red color.
It’s close enough to the sun that you get a good amount of daylight. And almost an Earth length day.
The atmosphere and gravity are light and breezy.
Sure, you would die if left exposed on the surface, but dressing for the weather is only an inconvenience compared to the super deadliness of the other planets.
It would be the best place for a vacation from Earth.
Venus, you’ve got so much going for you. You’re Sun convenient; you have a wonderful gravity. You would make a fantastic second home. But seriously, get a moon! And lay off on the atmosphere, then we’ll talk.
Mars is the most Earth-like. Even then it’s a cold barren wasteland. Something like Edmonton. But still, I like Mars.
I had to give a speech in grade 7 and my topic was Mars. I researched everything I could at the time (without Internet) and put together a pretty good speech.
Later I recall seeing pictures of the surface of Mars from the Viking landers. I was astounded that I was actually looking at pictures taken on another planet. I’m still astounded looking at pictures from the Curious probe. Another planet? It’s Star Trek, man.
I’m glad that Neptune is getting so much love. It’s such a jewel.
I’m going to try and head-off this argument (and probably fail, but hey). It’s just a matter of taxonomy, which isn’t a precise science. Pluto doesn’t care what it is called, it’s still the same object and just as interesting as it ever was. In 2015, a space probe will get there, and we’ll get a proper look at it.
There are two possible sensible definitions of “planet”. Roughly, one is “a gravitationally self-rounded object, of below stellar mass, orbiting a star.” The second one, which was adopted by the IAU, is a little more technical, but has more descriptive power, and I will try to explain why.
Using the first definition, the solar system has an unknown number of planets (probably at least 200, and possibly many more). Using the second definition, we can say “the solar system has eight planets, and numerous dwarf planets.” It’s also useful to distinguish between the terrestrial (rocky) planets, gas giants, and ice giants.
When the solar system was forming, the eight planets grew large enough to snaffle up or eject most of the material in their orbits. The dwarf planets did not, and ended up as the playthings of Jupiter and Neptune. The IAU definition isn’t perfect, but it does make sense. It also makes a cool little science story, of how to revise ideas in the light of new information.
Speaking casually, Pluto is indeed a planet. I think of it as planet, sub-category dwarf. We haven’t lost a planets, we gained numerous dwarf planets (Sedna, Eris, Makemake, Haumea, Varuana, Quaoar…). It’s exceptionally silly to get worked up about all this.
What sounds better?
Pluto, least and most pathetic of the nine planets.
Pluto, king of the dwarf planets. It’s the freakin’ Thorin Oakenshield of the planets.
Well, you’re the first one to type out multiple paragraphs trying to explain a side of the argument.
I like the Venus. Because we all know how awesome the Morning Star is.
Eris is bigger, and 27% more massive. Does that make it Durin the deathless? 
This board is supposedly for the purposes of fighting ignorance. Incidentally, the first asteroids discovered were initially described as planets.
Venus, cause women are from there and I’m all about the ladies.
When I was a youth, the elementary school library had a coveted book about space with big page-spanning artists renditions of the planetary landscapes and all that. It mentioned some theoretical method of terraforming Venus (sulfur consuming bacteria or something) that I’m sure was all science fiction woo-woo but sounded plausible enough to my 4th grade mind. When other people were all about Mars or hung up on the gas giants, I was sure that we’d be turning Venus into Earth v2.0 any day now.
Saturn because of the rings and also because Sun Ra came from there.
I also like the fact that Saturn is less dense than water. If you had a big enough ocean, Saturn would float in it.
