Throw planets past a star and keep every one of them in orbit. Too soft and it falls in, too hard and it flies away. A physics game for iPhone and iPad, with a friendly little sun to show you how.
For iPhone and iPad.
Grab a planet, swipe it sideways past the star and let go. The game does the rest with real gravity, the same way the Moon stays up.
Try it here. This is a tiny version of the game's physics: one star, no goals, as many throws as you like.
Grab anywhere, flick sideways past Sol, let go.
Ten-level campaigns around seven very different star systems, two ways to score, and a replay of every close call.
Three new star systems and thirty new levels, with gravity pulling from more than one place at once.
Every level is recorded. Afterwards, watch it again: fast between moments, slow motion through the near misses and crashes, with a timeline to jump anywhere.
Every level, every campaign and every Daily Challenge has its own board. See where you rank in the world, or switch to just your friends, all time, this week or today.
Earth, Mars, Mercury, Jupiter and the Moon are drawn from real spacecraft maps, lit by the star and spinning. Tap any planet, or the star, and the camera flies in.
Fun facts come first: how many times it's gone around, how long its year is, its closest shave. Tap More for real stats from NASA fact sheets and your orbit in real units.
Place stars, planets and moons with real mass ratios, and watch everything pull on everything else. Start from classics like three stars chasing each other round a figure-eight, a Tatooine world around two suns, or Jupiter's Trojan asteroids. No goals, no score.
Orbit Lab is a separate one-time purchase.
Score with perfect circles and lanes that never cross, or with hair's-breadth near misses, slingshots and cosmic billiards. Every win earns a style badge.
Every screen is laid out for the bigger display, in portrait or landscape. Great for small hands.
One new level a day, the same for everyone in the world, with its own leaderboard. Win three days in a row for a Moon badge, and keep going all the way to Artemis the Great.
Sol is a cheerful little sun who explains each new idea the first time it happens, in short voiced tips. Pick one of three voices, rewatch any tip in Settings, or turn tips off.
These are the real clips from the game. They start muted; turn the sound on in the player. Every tip is captioned, in the game and here.
Hi! I'm Sol, your friendly star! Let's sling some planets into orbit!
Each campaign is ten levels around a different kind of star, drawn here at their size in the game. Harder stars multiply your score.
Our Solar System
Learn the ropes around our own Sun, with Earth, Mars, Jupiter and friends.
Red Dwarf
The nearest star to the Sun. Half Sol's pull, slow orbits, and neighbors that tug.
Red Giant
An old star puffed up huge. Less room to swing, and residents in the way.
Neutron Star
Tiny, super heavy and spinning fast. Planets race around it.
More than one sun, and a storm of comets. Sold together or one by one.
Binary Stars
Two suns locked in a dance, pulling on every planet together. Out past them, they pull as one.
Triple Stars
Three suns chasing each other round a figure-eight. Find the calm lanes where they pull as one.
Comet Storms
A huge, blazing blue star in a cloud of icy comets. Watch for the glint at the edge: a comet is falling in!
The download and all ten levels around our own Sun. No time limit, no catch.
The gravity sandbox, with ready-made systems and your own creations.
Proxima, Crimson Giant and Azure Pulsar together, for less than buying them one by one.
