On a planet where the temperature is so high....?

We're basically looking for a ratio of ionization energy E(n), where n =4 and n = 1 (ground state). Electron energy levels of a hydrogen atom is given by:\n\nE(n) = 13.6/n^2 eV\n\nTherefore,\n\nE(4)/E(1) =  1/16\n\nIt takes only 1/16 of 13.6 eV , or 0.85 eV, to ionize the ground state electron from a hydrogen atom on this very hot planet.

venus' atmosphere is full of carbon and other greenhouse gasses and is thick and does not allow the sun's heat to escape. very little of the heat that enters the atmosphere escapes

The answer is yes! Most definateley! Being so close to the sun and not rotating on an axis makes for a huge temperature differential between the "light" and "dark" sides of the planet. This, through convection alone, makes for all kinds of geological activity. One must keep in mind that the conditions on that planet are far different from those on our own.

No other planets are habitable for humans.\n\nMercury and Venus being far too hot.\n\nJupiter, Saturn and Neptune for being gas giants and so has no solid surface. The gravitational pull of these planets would crush our bodies. Juipters gravititational pull is over 300 times the earth.\n\nPluto is too far away thus seeing temperatures of over -200 degrees C.\n\nMars would have been a perfect candidate, as the temperature is quite similar to earth's at occasion. But our lifes need plenty of water and the abundance of water on Mars is basically zero.\n\nFor other life than humans, a moon called Europa, which orbits Saturn, contains frozen methane and water, which could harbour life. The only problem is its a moon and not a planet.\n\nThere are all the other planets (approximately 250 so far discovered) in the Keiper Belt which need to be examined

There are many places on earth that are plenty hot - record-breaking hot. In fact, there's a good chance on the day this record-breaking temperature was recorded by a meteorological station in El Azizia in 1922 there were other places hundreds of miles away that were even hotter. In all likelihood, this record temperature has been exceeded since then in many places on earth, but we have no official records of the temperatures. It is important to note that when atmospheric temperatures are recorded it is not the surface temperature, where it can sometimes reach 150° F/ 66° C,

An increase of ozone around Mars would increase the temperature.\n\nHowever, there's two problems: \n\na) Mars does not have a large enough amount of mass to hold onto the amount of atmosphere required to raise the planet's temperature, and;\n\nb) Because Mars is smaller, it lost its heat much more quickly than the earth. Mars eventually cooled off to the point where its inner molten iron core hardened, destroying the magnetic field surrounding the planet. Because the earth is bigger, the core is still molten here, and we have a magnetic field which points our compasses in the right direction. Back to Mars - without the magnetic field, the atmosphere was exposed to the solar wind, which stripped it away. On Earth, the solar wind is stopped by the magnetic field, and it can only touch the atmosphere at the poles, where the air molecules ionize, creating aurora borealis and australis (The Northern and Southern Lights).\n\nMuchas your idea is a good one, it would require heating Mars' core and adding mass to the planet, which is currently impossible.

Actually, the earth isn't on a 35 degree tilt.  It is on a 23.5 degree tilt.

Some planets are too hot for water, some are too cold. The larger planets are made from methane and other gases.

Venus' temperature is more than 400 °C (750 °F) with temperatures at the surface reaching extremes as great as 500 °C (930 °F) in low elevation regions near the planet's equator

the temperature at the inner core of the earth is at the high is about 7,000 degrees Celsius

Temperature increases as pressure increases due to increased molecular collisions.  The Earth generates an incredible amount of gravity, meaning that everything is pulled towards the center of the Earth.  So at the center of the Earth is an incredible amount of pressure due to the incredibly high density of molecules moving around there, and thus the temperature is incredibly high!

Venus is the hottest planet. Mercury is closer to the sun, but atmospheric conditions also need to be considered.

Venus is the brightest object in our sky, after the sun and moon. Swirling clouds of sulphuric acid obscure Venus’s surface and inhibited study of the planet from earth until technology permitted space vehicles, outfitted with probes, to visit it. The probes determined that Venus is the hottest of the planets, with a surface temperature of about 462° C (864° F). Scientists believe a greenhouse effect causes the extreme temperature, the planet’s thick clouds and dense atmosphere trapping energy from the sun. So, Venus Have a high surface temperature.

Hey! I resent that answer above! It's something you should be concerned about, basically all the fumes people are emitting into the atmosphere (from factories, cars, etc.) are getting trapped in our atmosphere and heating the entire planet! This really shifts the balance of everything, there are many animals that can't live in the new heat they're not used to! If this keeps up, the earth will be smeltering!

It's 4000 degrees C at the center of the Earth. That'd pretty much do the trick.

Mars being very hot now is not a suitable condition for humans and plants, as we know it, to live.\nBut now that Water in the form of Ice has been confirmed, it is a possibility for us to live there, provided that the ice has to be vapourised to create water clouds, and subseqently the clouds should give out rain, and when this chain starts, the creation of oxygen could be obtained by growing plants which emit oxygen. \nWHEW. That my friend is a hectic task ahead (and probably not feasible also). So may be, just may be, that some where about at 200 years down it could be a dream come true.\n\nBesides, we would only be intruding the rules of the Nature by doing so.
