COSMIC GUIDE

Basic Controls

SPAWN: Drag items from the catalog into space to place them.
MOVE: Tap and drag any celestial body to reposition it.
INSPECT: Long-press any object to see its stats, speed, and habitability.

Physics & Orbits

PLANET ORBIT: New planets automatically lock into circular orbits around the nearest star.
BINARY ORBIT: Two stars will begin a gravitational dance around each other.
ZONES: Toggle "Zones" to see Boiling (Red), Habitable (Green), and Freezing (Cyan) rings around stars.

Galaxies & Exoplanets

GALAXIES: Ginormous 3D structures. If the Milky Way and Andromeda collide, they merge into a single stunning galaxy.
EXOPLANETS: Wildcard worlds with random colors, sizes, and textures. Many come with procedural ring systems!

Collisions

ABSORB: Larger planets consume smaller ones, gaining their mass.
EXPLODE: Similar-sized collisions result in a shower of rocky debris.
SUPERNOVA: Star collisions trigger a massive explosion that distorts space and vaporizes everything caught in the blast.

Special Anomalies

BLACK HOLE: A massive singularity that actively sucks in and destroys nearby matter.
WHITE HOLE: The opposite of a black hole; it forcefully launches objects away with extreme speed.
PROTO-DISK: Hold a star to toggle its disk. It will swirl with dust and slowly form unique, named exoplanets.
