Drag and drop planets and stars to make your own solar system. The physics engine will calculate how gravity between all of the asteroids, planets, and stars affect one another while they move through space.

Can you make a stable solar system? How about a stable solar system with a binary star?

Updated!!!!! So happy!!

I love this app and was introduced to it through the "Space" section in the nature and science museum here in Colorado. I am a 14 year old science freak and almost started a line to play Planet Families in the museum. I love this app and everything about it and it would be a great way to teach a class. I see that you have updated the game like so and I am so excited!!! Thank you so much!!

Star movement

The star moves so fast when I put a star in a huge star and when it stops I can’t put rocks 😕
