Eve

Eve is the second planet from Kerbol and is the second largest body orbiting it. It is purple in appearance. It has one small moon, a captured asteroid called Gilly.

Eve is the closest planet to 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 97,500 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. 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. During dawn and dusk, the sky is green. The atmosphere is possibly composed of iodine, given its purple coloration. 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. As with version 0.17.1 of aerobraking maneuver arriving from Kerbin and resulting in to orbit around Eve - without using fuel for braking - can be done aiming for at periapsis at aproximately 72500m. 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

Natural Satellites

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

Orbital Statistics

A geosynchronous 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.
