Star Sim 3D: Gravity in Space

Star Sim 3D: Gravity in Space is simple, but very addictive physics sandbox simulator of a gravity systems in space.

The only goal is to have fun while playing around with stars, planets and moons, observing the gravity forces between them and building up solar systems and even an entire galaxy. Want to do it in 3D? Also available!!

Follow a single planet on it's path through your solar system or experience how asteroids build up asteroid belts!
Explore real gravity patterns in 3D space - right on your fingertips!
Can you make a black hole?

OVERVIEW:
● Full 3D view support and intuitive swipe & pinch navigation
● Brand new achievements system added for even more free planets
● Completely new graphics, optimized asteroids belts performance and collisions
● Save and load planetary systems with system preview and online save and search
● Multiple planet skins and backgrounds

FEATURES:
● Easy build complete galaxy with stars, orbiting planets, moons and even whole asteroids clouds in this space simulator sandbox.
● Share your solar systems online and gather inspiration from shared online galaxies. Not sure what to look for? Search for a random solar system!
● Select a planet and follow it on it's path through your own solar system!
● Promote your awesome galaxy in the social media.
● Change planet's appearance to ensure your solar system or galaxy is most beautiful.
● You can view saved solar systems and galaxies from other players and store them locally, extend them and upload them back via the open space sandbox editor.
● Unlimited space sandbox simulator area! The gravitational interactions continue to work for all planets, suns and moons, no matter where are they in the galaxy and if they are currently displayed or not.
● Adjustable 3D view with simple controls.
● Online save and load so you never loose your galaxy or solar systems.
● Real physics simulator with pure gravity interactions between planets, moons, stars and asteroids.

● Adding planets in 3D mode.
● 3D view of each and every galaxy!
● Easy switch between 2D and 3D views when adding new planets, stars and asteroids.
● Open sandbox, zoom in and out, freely move the visible area as pleased.
● Beautiful space backgrounds - you can choose between several 3D space wallpapers.
● Simple creation one or more planetary rings and asteroids clouds orbiting a star.
● Planet collisions merge planet mass by following precise physics models.
● Planet color, size and gravity depend on planet mass, several predefined planet and star types available in the sandbox.
● Add whole asteroid clouds at once and observe the gravity interactions between hundreds of randomly placed meteors.
● Easy creation of moons in orbit of a planet.
● Several options to remove planets and stars: remove a single planet by selecting it, remove all planets at once or remove just the planets, that are not visible at the moment.
● Easy zoom to all planets, moons and stars, no matter where they are in space.
● Simple viewpoint navigation to the star or planet with the largest mass.
