Eve est la seconde planète autour de Kerbol et le second plus gros corps céleste orbitant autour. Elle a un aspect violet et possède une petite lune, un astéroïde capturé baptisé Gilly.

Eve est la planète la plus proche de Kerbin and the easiest to reach, requiring the least Delta-V of any planet. Having a similar size to Kerbin gives it a large gravity well, and a thick atmosphere makes landings easier, while making departure more difficult.

## Topography

 A topographic map of Eve made with the ISA MapSat plugin Eve has several oceans and large, flat continents with a few mountain peaks. There is a distinctly large crater in the western hemisphere. The surface looks like purple sand dunes.

## Atmosphere

 A comparison of the atmospheres of Eve and Kerbin Eve's atmosphere begins at 97,500m. It fades exponentially with increasing altitude, as do the atmospheres of Kerbin and Duna, but it is a very thick atmosphere; 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. In general, the atmospheric pressure on Eve at an altitude expressed in meters is:[1] ${\displaystyle p_{e}=5\ e^{-altitude/7000}}$ One observed deceleration profile is: 130 m/s at 11 KM, 110 m/s at 8.5 KM, 100 m/s at 7.5 KM, 90 m/s at 6 KM, 80 m/s at 4.3 KM. From within Eve's atmosphere, the sky appears indigo during nighttime. During dawn and dusk, the sky is green. The atmosphere is possibly composed of iodine, given its purple coloration. Jet engines function in Eve's atmosphere, to the extent of making noise and consuming fuel, but do not produce useful thrust, due to lack of oxygen to burn.

## Natural Satellites

Eve's only natural satellite is the tiny captured asteroid Gilly in a highly eccentric and inclined orbit. Gilly's surface is currently bugged, and it is challenging to land there.

## Orbital Statistics

The geosynchronous orbit of Eve is at an altitude of 10373.195 km above Eve. The speed of the satellite is 858.95 m/s and it has an orbital periode resonating with 1 Eve day (22.5 hours or 81000 seconds.) 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.
