The below link shows some greatest mountains pictures from Mars, Moon, Jupiter's moon, and Venus. No great mountains from Mercury.

The giant planets such as Uranus, Neptune and Pluton has no great mountains?

Cool collection but Space.com's interface makes my eyes and brain hurt. Those guys desperately need to get a new cleaner look and feel.

Uranus and Neptune are thought to be "ice giants", right? But if so, I would imagine their strong gravity would make the solid surface very flat. It would be intersting to orbit a synthetic-aperture radar system around one of them someday.

I agree with the comment about space.com's interface. There are a lot of lurid "space science" sites like space.com and centuri dreams, etc. I look at them, but don't consider them very reliable sources of science and fact. They're in the business of drawing in people to click on their google ads.

I've seen a cassini Radar image of saturn in a presentation by Linda Spilker (still trying to find it somewhere on the web), but it just shows more clouds... deep clouds though

This is a sin against nature: Pele is not a moutain (its next to a moutain, but not on a mountain):

http://www.space.com/php/multimedia/imageg...mgid=723&gid=58

On the same note: what does this have to do with mountains:
http://www.space.com/php/multimedia/imageg...mgid=725&gid=58

I like that they remember that Io has great mountains, but it would have been nice if they did some research and found good shots of mountains, more than just Tohil.

For those interested in Ionian mountains, try:

*Mongibello Mons
*Tohil Mons
*Tohil Mons - hi-res
*Shamshu Mons
*Hi'iaka Montes
*Zal Montes
*Euxine, Skythia, Monan, and Gish Bar Montes

A question for moon specialists, what is the tallest moon, from the surface?

According to the information sources, I have learned that the Moon has great difference between the bottom to the top, it is about 3 km below of the Moon reference radius and about 12-13 km above the reference radius (not sure how exactly but about that).

Do all of you think that Mount Everest is the higher peak on Earth above sea level ?
You're right BUT the farthest point to Earh Center is not the Everest, it's the Chimborazo (Ecuador) at 6 384.4 km while the Everest is at 6382.3 km

That's a cool fact. Of course they get to cheat at the equator, centrifugal bulge!

Boosaule Montes on Io is ~16 km above the surrounding plains.

I took time to find it out. The following is the needed information:
The deviations from the overall spherical shape of the Moon due to local topography can be substantial. The maximum and minimum variations are approximately +8 km/-9 km with both extremes occurring on the far-side of the Moon (relative to a sphere with a radius of 1737.4 km). The maximum surface elevations occur in the region surrounding the Korolev crater while the minimum elevations occur in the geographically nearby South Pole-Aitken basin. Both are of the far side.


That is about the same size of Earth (Mariana Fosa 10Km and Everest 8.8Km). Then, I think that Moon has a more accidented topographically than the Earth. The Earth topography is more rounded than the Moon by the eolian, and water erosions.

See post 7 here above. Everest is NOT the right comparison, isn'it? And you live closer than you think!

Hello Climber:

I think I have not expressed exactly. The comparision what I am thinking is about the size between the highest mountain and the lowest fossa. Your post about Everest vs. Chimborazo has surprised me. A very good hint!, So I am thinking that the tallest Peruvian mountain, Huascaran with its 6,749 msnm, very close to the equatorial line, might be third tallest mountain of the world? I have no info on how to measure from the center of Earth to the peak of Huascaran.

Hi Rodolfo,
It's not that simple! As an exemple when you get to "South Col" i.e. Camp 4 of the Everest on the Nepal's side, you can choose to climb to the left and go to the Everest or to your right and go to the Lhotse. The 2 summits are a few kms appart and Lhotse is at 8515m so "only" 335 meters less than the Everest.
I don't know either how to calculate, we'd better google this, don't we ?

"....Uranus and Neptune are thought to be "ice giants", right? ..."
That's a term that's being used, but I prefer the term "Vapor Giants" as opposed to Gas Giants (Jupiter and Saturn). Though the visible atmospheres of Uranus and Neptune are Hydrogen/Helium rich, the bulk of the "envelope" surrounding a high density core is CH4, NH3 and OH2 (H20). These are all condensable vapors and the visible clouds are presumably methane clouds.

There are no solid surfaces on or within either the gas giants or the vapor giants. Moons and terrestrial planets are made of "geology". The giants are made of "weather"

And where is Hawaii, the highest mountain (more than 10 km) and largest shield volcano on Earth? It is also, presumably, the home of Pele, the volcano goddess.
