Your solar system is alive — and it's yours to grow.
Dust drifts into orbit around your newborn star. Drag two matching bodies together mid-orbit and they fuse into something new: asteroids, comets, worlds, stars… and eventually things stranger than stars. Every object pays you Stardust each time it completes a revolution — your system is your merge board, your collection, and your idle income engine all at once.
🪐 MERGE A LIVING SOLAR SYSTEM — no static grids; everything orbits, glows and pays out as it circles.
📖 COLLECT FOREVER — the Cosmodex remembers every species you ever discover, each with a real astronomy fact, through every reset.
🔭 DISCOVER SECRET FUSIONS — cross-family merges create species you can find no other way. "Something cold met something warm…"
✨ HUNT RADIANTS — rare luminous variants worth triple, with a fair pity guarantee.
🛰 LAUNCH PROBES — send them out and they return with surprises. All odds shown, always.
💥 GO SUPERNOVA — collapse the system, keep your discoveries, and grow back stronger with Dark Matter.
🌌 TRAVEL BETWEEN SOLAR SYSTEMS — zoom out to a galactic scale, then a cluster, then beyond — each a fresh system with its own worlds to collect. There is no final wall.
🎪 EVENTS EVERY FEW DAYS — a fixed rotation of six themed events. Missed an exclusive? It returns with the event, guaranteed.
Fair by design: no forced ads, ever. Rewarded bonuses are opt-in and capped — and VIP members get them automatically with zero ads. Every species is reachable without spending.
Whether you play for twenty focused seconds or leave it running all day, Merge Orbit keeps growing. Come back to a system that earned while you slept, a new discovery waiting, and always one more merge.
From the makers of Idle Orbit and Idle Black Hole.
Merge planets, collect a living galaxy, and let your orbits earn while you rest.
