Class IV gas giants have primarily hydrogen and helium atmospheres with carbon monoxide and upper clouds of alkali metals above lower cloud layers of silicates and iron compounds, hence the brighter colours. The temperature of their upper cloud layers is typically above 900 K.
— In-Game Description
Maher Prime, the brown dwarf of approximately 50 Jupiter masses, is particularly interesting as it was first discovered in the early 21st century. It has an unusual orbit – very nearly perpendicular to the orbital plane of the other bodies in the system at about 10.7 AU from i Boötis B,C – any other orbit at this distance would be unstable because of strong tidal forces from i Boötis A. It was almost certainly captured by i Boötis B,C in a recent close encounter.
