![]() At the poles, the temperature varies between 87 ☌ and 95 ☌. At the equator, sea level temperatures vary between a nighttime low of 147 ☌ and a daytime high of 156 ☌. The temperature rise above 70 km suggests the presence of a thermosphere in this area(70km to the Kármán line(90km)Īir temperatures vary with latitude and time of day. Despite the hot surface temperatures, the lack of a stratosphere means that Eve's atmosphere is cooler than Kerbin's at altitudes above ≈26.5 km. Above 70 km, the rarified atmosphere warms as altitude increases. Except for a small inversion layer between 50-60 km at low latitudes, air temperatures decrease with increasing altitude up to an altitude of 70 km. The surface of Eve is extremely hot, with a globally averaged sea level temperature of approximately 135 ☌. The following table below gives the atmospheric pressure at various altitudes above sea level. The pressure-altitude profile is globally constant and independent of temperature. The scale height varies with altitude, which is a change from pre-1.0 versions of the game. Like all other atmospheres in the game, Eve's atmosphere fades exponentially as altitude increases. An atmosphere of 90% CO 2 and 10% C 2H 6 would have molecular weights and adiabatic indexes close to what is seen on Eve, though there are other combinations of gases that would work as well. With a thick atmosphere filled with hydrocarbons, it is easy to imagine reactions that would yield compounds such as RP-1, the grade of kerosene used as rocket fuel. If we assume LiquidFuel is kerosene, the joke that the lakes of Eve are LiquidFuel is strengthened by the purple colour since it is often mixed with a purple dye prior to sale. Another possibility is that the atmosphere is filled with ethane gas (C 2H 6, with a heat capacity of 1.2 and a molecular weight of 30 g/mol) and other compounds. Although the composition of Eve's atmosphere is unknown these values suggest that it may consist largely of carbon dioxide. The average molecular weight of Eve air is 43 g/mol, and its adiabatic index is 1.20. The pressure at the top of Eve's highest mountain peak is 2.4 atm. At an altitude of 14,579 m on Eve, the atmospheric pressure is the same as at sea level on Kerbin (1 atm). Compared to the atmosphere of Kerbin, Eve's atmosphere has 4 times the mass and 5 times the sea level pressure. (updated) Comparison of the atmospheres of Eve and KerbinĮve has an extremely dense atmosphere with a mass of approximately 1.9×10 17 kilograms, a sea level pressure of 506.625 kilopascals (5 atmospheres), and a depth of 90,000 meters. Eve's highest mountain range has a peak of 7526 m. These are speckled with small boulders, no doubt worn down by Eve's pressure, temperature, and winds. The terrain has a few mountain peaks but mostly consists of rolling hills that resemble purple sand dunes. ![]() It has several oceans, among which lie large, flat continents. The surface of Eve seems to looks not unlike that of Saturn's largest moon, Titan. Actually, it’s not very similar at all is it? Who are those people?'' Well, despite the purple, and the toxic atmosphere, and the extreme pressures and temperatures. It is considered by some to be almost a sister planet to Kerbin. It’s one of the larger, most visible objects, mainly because of its very, very purple tint. This makes it extremely hard to send missions there because of the Eve Effect.Ī tutorial to get to Eve is available at the link.Įve is certainly the purplest object in the solar system. Additionally, Eve has the greatest surface gravity of all the planets, and the second highest escape velocity, second only to Jool. It is especially notable for its extremely thick, dense atmosphere, which makes aerobraking and returning two of the most dangerous activities in the game. It has one small moon: a captured asteroid called Gilly. ↑ 1.0 1.1 1.2 1.3 The distances are given from the body's center, not from the surface (unlike ingame)Įve is the second planet from Kerbol, the closest planet to Kerbin, and KSP's analogue for the planet Venus.
