Caeruleum Lagrange Cloud
A dense accumulation of gas fixed in place at a Lagrange point, where the combined gravitational forces of multiple bodies create a stable region.
— In-Game Description
A Lagrange Cloud is a form of Notable Stellar Phenomena. Using the Full Spectrum System Scanner, they can be found at the Lagrange points of a star system, along the orbital plane. There are several variants with different colors, and some feature electrical storms. Various astronomical objects and biological entities can be found among Lagrange Clouds and catalogued using the Short Range Composition Scanner.[1] The Lagrange cloud is automatically identified and entered into the Codex while entering the cloud.
In real life, such clouds can be found at the L4 and L5 Lagrange points of the Earth-Moon system and represent two clusters of fine cosmic dust. Such clouds are called Kordylewski Clouds .
Groups & types[]

Purple Lagrange Cloud
Lagrange Clouds can be divided into 3 groups:
- Lagrange Cloud
- Lagrange Storm Cloud
- Porto-Lagrange Cloud
13 types of Lagrange Clouds are recorded in the Codex:
- Caeruleum Lagrange Cloud
- Caeruleum Lagrange Storm Cloud
- Croceum Lagrange Cloud
- Croceum Lagrange Storm Cloud
- Luteolum Lagrange Cloud
- Luteolum Lagrange Storm Cloud
- Proto-Lagrange Cloud
- Roseum Lagrange Cloud
- Roseum Lagrange Storm Cloud
- Rubicundum Lagrange Cloud
- Rubicundum Lagrange Storm Cloud
- Viride Lagrange Cloud
- Viride Lagrange Storm Cloud
All of these types, except Proto, have storm cloud variants. Explorers should exercise caution when entering Lagrange clouds, because certain actions, such as scanning or turning on external lights, may cause a reaction.
