Variable: DEFAULT_CORE_RADIUS_RATIO
ts
const DEFAULT_CORE_RADIUS_RATIO: 0.55 = 0.55;Default ratio of the solid core radius to the visual surface radius. Used by all non-stellar bodies (rocky / metallic / icy / gaseous) when neither BodyConfig.coreRadiusRatio nor BodyConfig.gasMassFraction is supplied. The core occupies the sphere of radius config.radius * DEFAULT_CORE_RADIUS_RATIO; the remaining shell [coreRadius, radius] is shared by the sol + atmosphere layers.
