Eve je druhá planeta systému Kerbolu a zároveň je druhým největším tělesem, které hvězdu obíhá. Má fialový vzhled. Má jeden malý měsíc, zachycený asteroid nazvaný Gilly.

Eve je nejbližší planeta ke Kerbinu a nejlehčí cíl, s potřebou nejnižší Delta-V jakékoli planety. S velikostí podobnou Kerbinu, má i podobnou gravitaci. Její hustá atmosféra umožňuje lehké přistání, ale také činí vzlet z planety téměř nemožným, s potřebou nejvyšší Delta-V jakékoli jiné planety.

Topografie

Atmosféra

Porovnání atmosfér Eve a Kerbinu Atmosféra Eve začíná na 96,708.6 metrech a je extrémně hustá: v 11,250 metrech, je hustá jako atmosféra Kerbinu nad hladinou moře (1 atm) a tlak její atmosféry na povrchu je 5 atm. Její atmosféra řídne exponenciálně, s výškou 7000 metrů. In general, the atmospheric pressure on Eve at an altitude expressed in meters is:[1] ${\displaystyle p_{e}=5\ e^{-altitude/7000}}$ 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.[2] 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.
