|“|| Gilly is a lumpy rock wandering around the orbit of Eve. It’s by far the smallest natural satellite that the Kerbal Astronomical Society has discovered.
Due to the large amount of squinting and eye strain associated with its discovery, wearing glasses has now become synonymous with being an accomplished Astronomer.''
Topographycaptured asteroid. Gilly has the lowest mass and gravitational force of any body in the Kerbol system. Due to its minuscule mass and gravitational force, it does not have an atmosphere.
Gilly's color might come from a high content of solid carbon. When terrain scatters are enabled in the settings menu, small rocks show up on the surface.
Gilly has the least gravity of all bodies in the Kerbol system at only 0.5% of Kerbin's surface gravity, which is half that of Jool's moon Pol. It is very impractical to walk on Gilly; each step will launch a Kerbal several meters into the air. A Kerbal can jump over 200 meters on this moon and will usually take more than 4 minutes to return to the surface. This makes jetpacks a necessity to move around the moon practically.
The low gravity also makes it very difficult to get into an encounter since it makes the sphere of influence so minuscule. An unplanned encounter with Gilly is unlikely when approaching Eve, even if the craft's trajectory is near the plane of Gilly's orbit. Gilly's mass is very small relative to Eve's mass, resulting in a very small sphere of influence compared to the semi-major axis of its orbit. In fact, no other moon in the game has a smaller mass ratio.
Gilly's gravity makes it ideal for very low fuel interplanetary missions; however, its eccentric and inclined orbit may make encounters more difficult and fuel-costly.
Landing on Gilly is challenging due to its very low mass, steep slopes, and highly eccentric orbit, making it very easy to overthrust engines or send a spacecraft tumbling. Gilly's odd shape and fast rotation give the surface near the peaks an apparent velocity near 5 m/s. Some players advise to keep the prograde on the navball tilted a little bit sideways to counter the Coriolis effect if you are landing close to the equator. To prevent tumbling upon landing, the final velocity trim may need to be performed by eye. It is advised to be adept in manually using RCS thrusters and to have SAS active on the lander. Time Warp can also be used to stabilize a lander, as vessels tip over so slowly on Gilly the game considers them stable enough to allow time warp.
Escaping Gilly is much easier — the EVA jetpack can easily put a lone Kerbal into orbit or set him on an escape trajectory. In fact, it's possible to deploy a Kerbal from a spacecraft in orbit around Gilly, send him down to the surface, and land him without using any other fuel source. The Kerbal can even return to orbit, rendezvous with the spacecraft, and still have up to 3.5 units of EVA fuel left.
