The following is a list of content that was stated at one point by a developer to be planned to be added to Kerbal Space Program, but was never implemented into the game.

New Celestials

Xubol

A near-molten ball of salt and sand, Xubol was to be the first planet of the Kerbol System.^[1]

Gas planet 2

~50% larger than Jool, with rings.^[2]

• Eeloo: Relocated to orbit GP2, now with large geysers that can knock ships around.
• Daphy: Unusually smooth and round ball of fluff. An asteroid which has accumulated material from the rings, practically no gravity.
• Potatus: Small moon with relatively high inclination relative to GP2's equator. Composed of ices surrounding a highly dense core. Very rapid rotation (21 minutes) causes it to be stretched into an oblate spheroid.
• Fonso: Largest moon, ~300 km radius. Very mountainous, with a thick atmosphere that only extends partway up the mountains (the mountain peaks are in vacuum, while the proper surface is at two atmospheres).
• Tiny moons: Same case as Jool.

Gas planet 3

Perhaps not an actual gas planet, could be a 2000km rocky planet with a thick atmosphere, with 6g and 30 atmospheres of pressure at the surface.

• Possible moon with rings, would have to be diffuse rings as well as recent, fully-formed rings wouldn't last long in that position.

Mez

Super-Kerbin with rapid rotation period, somewhat lens-shaped as a result.

• Thick atmosphere
• Gravity at poles approaches 10-20g, gravity at equator only ~0.05g.
• Scale height of atmosphere varies accordingly, and grows very diffuse and stretched around the equator.

Miscellaneous

• Low-density belt of vulcanoid asteroids below the orbit of Moho.^[3]
• Asteroids discoverable in the actual asteroid belt, along with a significant quantify of larger asteroids.
• Additional gas planets beyond the third one.
• Extra bodies with analogues of most real-world dwarf planets (especially Sedna).

Changes to Existing Celestials

Eve

• Inclination reduced to make an easier early-game interplanetary target.
• Hotter and generally more angry atmosphere on Eve.
• Not as purple.
• Perpetual clouds and heavy haze, thunder ambiance, flashes of lightning and a surface dark enough to require lights to see properly (except when the lightning is going).

Kerbin

• Small amounts of eccentricity and inclination.

Mun

• More realistic crater distribution in both size and location.
• Tycho crater ripoff with properly shaped solid-black monolith.

Duna

• More, flatter lowlands, more obvious ancient water-carved features.
• More irregular ice caps with "super cool" features.
• An additional asteroidal moon, far beyond Ike, if the systems allowed it it would have irregular rotation like Pluto's small moons are expected to (due to the odd dynamics of a binary planet system).

Ike

• Return of the magic boulder.
• Craters and a more moon-like heightmap.

Jool

Actually the second-smallest gas giant, with unusually large moons. All other gas giants would have objects smaller than or comparable to Moho.

• Re-arrangement of major moons to be more widely spaced and similar to Saturn's layout of moons.
• 150% its original size, with enlarged moon orbits as well.
• Not so green, perhaps green bands instead, which when sampled yield algae.
• Oblateness similar to that of Saturn's or Jupiter's (would require reworking of how atmospheres are handled).
• More tiny moons: Just a bunch of small moonlets, at least 20. Probably would be nameable by the player or given designations (ex. J-17 for the 17th moon of Jool discovered).

Laythe

• Very volcanic because of its proximity and the tidal forces from the other moons. Still oceans of water, but now with actual active volcanos with lava lakes (that destroy things).
• Smaller, Duna sized.
• Mostly cloud covered.
• No ice caps (hot greenhouse atmosphere would destroy them easily).
• Faint torus of gas along its orbit from escaping atmosphere (not enough to affect ships, but enough to catch the light, as in Saturn's E ring (possibly enough to change orbits using aerodynamic surfaces).

Vall

• More like eeloo, with large cracks in the ice and a more chaotic surface.
• Smaller, Mun sized.

Tylo

• Perhaps turned into a highly-contrasting body like Iapetus.
• Smaller, slightly below Duna sized.
• Two-thirds-gee surface gravity (High for a body of that size, so perhaps a dense iron core surrounded by ices; a body from the inner solar system that was ejected and then captured by Jool).
• Ice geysers + resulting atmosphere.
• Second faint gas torus.

Eeloo

• Surface like Pluto with "flowy stuff".
• Small blob of a moon.

Technical advances

• Functional atmospheres for non-spherical bodies.
• Proper altitude detection for non-spherical bodies.
• Non-spherical atmosphere rendering.
• Gas torus rendering.
• Dynamic loading/unloading of planet surface maps to keep memory usage sane (or just 64-bit and deal with the inefficiency).
• Ambient sound system for planets.
• Irregular planetary rotation (optional, for Duna's minimoon).
• Clouds.
