## What is Planet Families?

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?

## Key features

- Create custom solar systems
- Drag and drop planets and stars
- Realistic gravity physics engine
- Simulate celestial body interactions
- Build stable solar system configurations
- Challenge with binary star systems

### 4/5 — WOW

*2023-10-08*

OkSo is playing the game and when I was playing the game, I was just adding up a bunch of stars together and make the star bigger and then there’s explosions happened and it was like basically there was this. That seem to have more of like the most mass do better than getting updated because I’m pretty sure it’s pretty much junk drawer and I want to Zach B. me removed because you’re definitely not a OK this is why I don’t use the microphone well I’m still stay saying it so yeah.

Pee Drawer

### 5/5 — Make a moon orbit a planet

*2021-01-17, version 1.1.01*

Make a moon orbit the planet and size changer and also planetary collisions

### 5/5 — Good

*2020-06-09, version 1.1.01*

Yah it’s good for the makings it’s my dream

### 4/5 — Dean’s Tile

*2019-05-29, version 1.1.01*

### 4/5 — I’m back

*2019-02-09, version 1.1.01*

It is now ⭐️⭐️⭐️⭐️ this is awesome but can you make it so you can zoom out infinite

### 5/5 — Star movement

*2018-10-20, version 1.1.01*

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

### 5/5 — Updated!!!!! So happy!!

*2017-05-31, version 1.1.01*

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!!

### 4/5 — I expected more

*2015-09-03, version 1.0.5*

This app is really great for understanding how gravity works, you can even add Suns to influence the pull of gravity, which I liked. But that's really all it does. I expected to be able to explore each planet and understand how their distance from the sun affected the length of their days, years, and how it influenced the planet's gravitational pull. I became bored very quickly, but it wasn't a terrible app.
