1P/Halley – Comet Nucleus with Gas Emissions This model depicts 1P/Halley, one of the most famous periodic comets in the solar system. The nucleus is represented as a dark, irregular body with a rugged, uneven surface, inspired by observations from historic spacecraft encounters. Localized gas emissions are modeled using semi-transparent geometry and emissive materials to suggest natural outgassing as volatile ices sublimate when the comet approaches the Sun. The faint blue-violet coloration reflects ionized gases commonly associated with cometary activity in space. The emphasis of this model is on surface detail, shape, and atmosphere rather than simulation, using lightweight geometry and real-time-friendly materials suitable for interactive viewing.
