Most fascinating non-Earth planet in solar system IYO

Any of the gas giants (Jupiter, Saturn, Uranus, Neptune) are fascinating. Jupiter and Saturn don't have hard surfaces and Jupiter's Big Red Spot is the size of three Earths. Uranus and Neptune are nothing but frozen oceans with winds exceeding 1,000 MPH. I wish we could have clear photos of these places. Mars is overrated.

Jupiter hands down. Any other answer is invalid.

Neptune looks cool I guess.

Saturn was the first "other planet" I discovered as a child so it's always been special to me.

Jupiter, more specifically Jupiter's moons because there is potential for life on Europa.

Since the discovery of exoplanets, I've found the majority of planetary bodies in our Solar System rather boring.

The chemistry/physics related to Jupiter's atmosphere is still fascinating though (and having what is essentially magma made out of hydrogen at lower levels).

Jupiter, because it's easy as **** to find with a telescope.

Jupiter. It is the literal definition of awesome.

Don't gerg me, gergy boy.

Uranus,... sounds funny. lol

Saturn's moon: Titan. I like the way the hydrocarbon seas look.

STill has to be mars though, there was water there, and it's almost an habitable planet.

Venus and mercurius are just too unfriendly for human life and the others are made of gas and/or are too far away to visit.

It's going to be very exciting if people actually set foot on mars because maybe they'll be able to do something over there, who knows. The one way trip from my friendly neigbour the dutchie is just inhumane. We should stop him or fund him more if he takes care of a (possible) return trip.

Mars, Jupiter and Saturn are all easy to find in the night sky with the naked eye. Venus also.....at the right times at dawn or dusk

Saturn. The rings are awesome.

Venus, because awesome.

It's gotta be Europa, the idea that there are sea monsters on Jupiter's moon is fun.

For me personally, Jupiter is the easiest to find. It is the third brightest object in the sky and remains predictable compared to Venus. It lasts pretty much all through the night. Other planets such as Satarn are harder to find without the use of an sky app. Nothing is really needed for Jupiter, it's fairly distinguished in the night sky.

It's generally more interesting as well because the physicality of it is noticeably different on a amateur scope wither it be the moons around it or the shape shifting surface. I'm very lucky as well in that both Jupiter and Orion almost past direction in front of my window the majority of the time. I actually barely need to move the telescope an inch most of the time or haul it outside.

This is my current telescope which replaced my 114eq. It's still a cheap amateur scope but miles better than the one I had before. It supposedly 500 times zoom. Although I usually use 6mm and 20mm which (I think) is 900 divided by 6 = strength 150. I would guess (using the power of math) 2mm would be max zoom but that probably means a tiny fov and distortion. I's never tried it. The 6mm has been fine for the most part.

For looking at Jupiter or Orion it's perfectly fine. Even a pair of binoculars will do for when I can't be arsed setting up the telescope. I'm in Scotland surrounded by basically no light sources with 20+ miles of farm land on either side. It's pretty much an astronomers wet dream.

europa, because of the possibility of discovering life there.

Your anus.

Uranus and all its moons. The last probe have visited this planet was Voyager 2. Reading through information we know so far on this planet is vague and so are its five large moons. A permanent orbit and a lander would help shed some light.

I think Venus is a fascinating planet. I am intrigued by the surface photos sent back by the Venera probes that the Russians sent out. Despite being made to survive very harsh acidic and high pressure environments, the longest any of them lasted was about 2 hours, but they sent back some incredible pictures for that short time.

Saturn. No explanations needed.

Here's an interesting Wikipedia page for astronomy lovers by the way.

Yeah, i find that planet really interesting.

Planet "miller" ..... the gigantic wave is facinating

Venus. Then again I'm not very interested in astrology.

@alim298: Not trying to sound smartass, but I'm guessing you mean astronomy.

Ceres. There's just something cool about a protoplanet. Can't wait till next year, Ceres and Pluto!

Well shit. Yeah I meant to say astronomy. I'm just glad I didn't say anus instead of venus.

Are you a single lady?

Also for me it has to be Mars... it's the one with likely the most answers to our questions.

Jupiter has rings as well.

Nah dude, im a big burly man.

Saturn

Saturn, Europa and Enceladus.

I'm a fan of Neptune.

@RadecSupreme: Oh well Tolkien showed us that big burly men can also have a desire for nice jewelry

Jupiter and it's moon Europa for sure.

Pluto because of the size and proximity of its largest moon!

Amazing view!

(Yes pluto not a planet)
