ExtraPlanets
by MJRLegends
Players who want Galacticraft to reach beyond the Moon can add ExtraPlanets, which brings a set of additional planets, rockets and vehicles for Forge.
What it does
ExtraPlanets extends Galacticraft with planets and moons that differ in gravity, temperature and day length, and with biome systems that cover most of the bodies. Rockets come in tiers from 4 to 10, and custom launch pads and custom vehicles let players reach the new worlds. Dungeons of Tier 4 to Tier 10 sit on the outer planets, and Pluto and Eris keep the Creeper bosses for now, with replacements planned.
The mod requires Galacticraft 4 build 184 or higher, Forge 13.20.1.2513 or higher on 1.11.2, and MJRLegendsLib. Each release targets a single game version. Files are published for 1.7.10 – 1.12.2, and the latest file is 1.1.3 for 1.11.2. Every player and the server need a copy of the mod. The code is not open source; it is released under All rights reserved, and public links exist for the source code, issue tracker and wiki. ExtraPlanets is required by GalacticraftCompatibility.
Key features
Additional planets and moons
Bodies with their own gravity, temperature and day length extend the Galacticraft solar system.
Tiered rockets and pads
Rockets range from Tier 4 to Tier 10, and custom launch pads send them toward the new worlds.
Custom vehicles
Vehicles are added alongside the rockets, and the Electric Rocket is available on the newer builds.
Thermal armour and dungeons
Thermal armour pieces up to Tier 3 protect against the new environments, and dungeons on the outer planets reach Tier 4 and above.

How it compares
More Planets is open source under the MIT License and runs on Forge for 1.7.10 – 1.12.2 with the same client and server environment. Galaxy Space is an addon for Galacticraft that targets only 1.12.2 and is released under All rights reserved, so it is not open source. Galacticraft-Legacy is open source under the MIT License, also for 1.12.2 only.
