It's certainly one of the more interesting planets. It must have taken quite a massive knock to be spinning on its side like that :P .

I imagine it must have been...but, how did a solid meteor collide with a gas planet :S ? Surely it would just have gone straight through?

I think the gas planets have a solid core

They do, but what if the meteorite doesn't go through the core?

Uranus also has quite a nice ring system. It isn't as impressive or beautiful as Saturn's, but it's easily second best in the Solar System:

Wow that's a neat illustration....


Moons of Uranus

A montage of Uranus' large moons and one smaller moon: from left to right Puck, Miranda, Ariel, Umbriel, Titania and Oberon. Other moons are not yet photographed in detail. Original pictures were taken by NASA's Voyager 2. Size proportions are correct.

That's very neat!

Miranda's my favourite of Uranus' moons. Parts of its original surface are buried, and parts of its original core now lie on the surface! This is probably because it was smashed apart by an asteroid impact, and gravity brought all the pieces crashing back together.

I wonder whether the Earth is similar? The Moon was created by a large asteroid hitting the Earth. Then again, I don't think the Earth was smashed apart in the impact; just partially melted by it.

Uranus is definitely my favorite planet. I just love how unique it is with it's arrangement for it's rings, and I love the shade of blue it has.

I've always thought of it as green :P, but I suppose it is a sort of blue-green (and, of course, it's blue in the picture).

Personally, I prefer Saturn's rings, although Uranus's look good too.

I personally love Saturn's rings more too.


This is a beautiful one:

It is. I really like that green-blue colour; it's much nicer than the false-colour image in the opening post.

Yeah, I know. I love that colour more.

Why can't you land on the gas? Will it be possible one day?

There's just no solid surface...you'd just fall straight through it. It is gas, after all.

Then how is there mass and storms and where do the rings come into place? Is there a section that people could actually walk on?

In the same way that the Earth's atmosphere (which consists of gas) has storms and mass (albeit a very low mass).

The rings, however, are solid, since they consist of countless rocks, boulders and dust and ice particles. However, the biggest of these would be only be a few metres across, so it wouldn't have sufficiently strong gravity to hold a person down so they could walk on it.

The only bodies associated with the gas giants on which you would be able to walk are their moons....I can certainly imagine astronauts visiting some of them one day.

I'd love it if we could have shuttles that go into Uranus's atmosphere.

That might be possible one day. Because of Uranus's large size compared to its mass, gravity there is actually slightly weaker than on Earth (8.69 m/s² on Uranus, as opposed to 9.81 m/s² on Earth), so any shuttle that isn't crushed by Earth's gravity won't be crushed by Uranus's, and any shuttle that can escape from the Earth's gravitational pull could also escape from Uranus's.

Highly doubtful - it's extremely cold out there. Even if we got around that, they wouldn't have any fertile land for farming or growing food, and there'd be nothing eat. We'd have to bring crops from Earth (or some other planet that we had colonized) and grow them there. It'd be a very major terraforming project.

That'd be fun, but ruins the beauty of them!
