Eve/Data

"Eve" a második bolygója a Kerbolnak, és a Kerbin legközelebbi szomszédja, és KSP Vénus bolygó változata. Egyetlen aprócska holdja van: egy befogott aszteroida a "Gilly".

Játékbeli leírás [In-game Description]

„

Eve valószínűleg a leglilább test a rendszerünkbe. Ez egyike a nagyobb és legjobban látható égitesteknek, köszönhetően a nagyon-nagyon de nagyon lila árnyalatának. Sokan úgy tartják, hogy ez félig-meddig a Kerbin testvérbolygója. Nos, eltekintve a lila mérgező légkörétől, az extrém légköri nyomástól és hőmérsékletekől... Jelenleg nem is nagyon hasonlít, ugye? Kik ezek az személyek? — Kerbal Asztronómus Közösség

Topography

The surface of Eve looks not unlike that of Saturn's largest moon, Titan. It has several oceans, among which lie large, flat continents. The terrain has a few mountain peaks, but mostly consists of rolling hills that resemble purple sand dunes. These are speckled with small boulders, no doubt worn down by Eve's pressure, temperature, and wind. Eve's surface is covered with craters. The composition of the violet liquid which fills the oceans and lakes is unknown, although water remains a possibility: the boiling point of water is slightly higher than the surface temperature when taking the high atmospheric pressure into account. According to the devs during a livestream, it was joked that the lakes were made of rocket fuel. Eve's highest mountain range has a peak of 7526 m.

Atmosphere

A comparison of the atmospheres of Eve and Kerbin

Eve's atmosphere begins at 96,708.6 m and is extremely dense: at 11,250 m, it's as thick as Kerbin's atmosphere at sea level (1 atm), and at Eve sea level the atmospheric pressure is 5 atm. Its atmospheric pressure fades exponentially, with a scale height of 7000 m. The atmosphere should be superheated due to the thick atmosphere trapping in heat, much like Venus, but this is not currently implemented.

In general, the atmospheric pressure on Eve at an altitude expressed in meters is:

$p_{e}=5\ e^{-altitude/7000}$

From within Eve's atmosphere, the sky appears indigo during nighttime and a violet-purple color during daytime. During dawn and dusk, the sky is green.

Jet engines do not function in Eve's atmosphere, since it contains no oxygen — they make noise and consume fuel, but they produce no thrust. Planes with other propulsion methods do, however, work very well, and are a great way to explore the planet. They work best between 35 km and 25 km where the atmosphere generates enough lift to glide and steer, but not enough drag to slow the aircraft excessively.

As with version 0.17.1, an aerobraking maneuver arriving from Kerbin and resulting in orbit around Eve - without using fuel for braking - can be done aiming for a periapsis at approximately 72,500 m. In rare cases, retracted solar panels may still be destroyed by Eve's atmosphere.

The following table gives terminal velocities at different Eve altitudes. These are also the velocities at which a ship should travel for a fuel-optimal ascent from Eve, given the game's model of atmospheric drag.

Altitude (m)	Velocity (m/s)
0	58,4
1000	62,5
5000	82,0
10000	115
15000	162
20000	228
30000	450
40000	888
50000	1,76×103
60000	3,47×103

Science

Eve's orbit and atmosphere have a science multiplier of 7, which is rather average. But the surface has a multiplier of 12, which is the highest science multiplier in the whole star system.

Currently(0.23^[outdated]), Eve has no biomes, only the default "global" context for science activities. Some players have mistaken the difference in results given when in water and the header "from Eve's oceans" for a second biome, but this is default terminology coded for a "SrfSplashed" splashdown situation also seen on Laythe.

Natural satellites

Eve's only natural satellite is the tiny captured asteroid Gilly in a highly eccentric and inclined orbit. Gilly is the smallest celestial body in the Kerbol system.

Orbital statistics

Visiting Eve potentially requires the least delta-v of any planet because its huge gravity well and dense atmosphere mitigate the difficulties that its slight relative inclination poses and greatly ease aero-captures, transfers, and landings; unfortunately, takeoff and escape therefore require the most delta-v of any celestial body with a solid surface.

The combination of high gravity and thick atmosphere makes return missions from the sea level of Eve very difficult. It requires about 11,500 m/s of delta-v to get into orbit from sea level. Driving to and launching from the peak of one of Eve's mountains can drastically reduce the amount of delta-V required (thus allowing successful launches with significantly lighter rockets). The highest peak on Eve since verzió 0.21.1 is 7540 m high, found near (25° S, 158.5° W)

Altitude (m)	Delta-V Required (m/s)
0	11,282
1000	10,731
2000	10,219
3000	9,743
4000	9,300
5000	8,888
6000	8,507
7000	8,150
7540	7,968

A synchronous orbit of Eve requires an altitude of 10373.195 km and a velocity of 858.95 m/s. For a semisynchronous orbit of ½ Eve day (11.25 hours or 40500 seconds) an orbit of 6275.676 km above Eve is needed with a velocity of 1082.2 m/s.

Bugs

• Eve has higher gravity than Kerbin, restricting a Kerbal's jump to only half a meter and making EVA jets useless. This being said, if a Kerbal falls from more than 4 m, they will hit the ground much harder than on Kerbin, which may cause them to clip into the terrain and accelerate away from Eve at phenomenal speed, usually sending the unlucky Kerbal on an escape trajectory from Kerbol if they are not killed by the fall. They may bring something into interstellar space with them if they hit an object instead of the ground.
• Solar panels will probably break off in flight, even with very low velocity. It's best to wait to extend them till stable on the surface, however they can break on the surface of Eve even when retracted. This may be due to Eve's high gravity.
• Rovers can be challenging to drive on Eve due to its gravity. The rover's wheels will easily break.

• Landing legs on Eve can easily break because of Eve's high gravity.
• When landing fast, craft will sometimes sink into the surface of Eve. This can be fixed by using landing legs to lift the ship up.
