We are giving you the keys to the universe. Think you can build a solar system that can maintain the balance and spawn life? Design your own planets and stars and try your hand at the interactive Solar System Builder. But construct carefully, the fate of your planetary system requires keen celestial reasoning and understanding of gravity's pull.

it wont let me play,it just stops at the screen with the cosmos,what do i do?

Yes,only the rocky water planet has life on it,but,here's a tip,if you want to make your rocky water planet to have life faster,make its orbit not to close and not to far from your sun.

are rocky water worlds the only thing that make life?

If we separate a parts from a body then the parts can not survive so how I exist with out World Family.

to survive forever point all your planets facing outwards

Wow! I've just done a moon (water planet) rotating around a gas planet!

It needs to have better instructions..

I made a mistake with the speed.

one planet, 100,000 years and counting

the orbit is very eccentric though.... (elliptical)

life lasted about 65000 years

How do you make a planet orbit another planet? In other words how do you make a moon?

5 planets. four rocky one gas (not giant). The first planet from the sun is stopped and the sun postally used by another planet for the second planet is pushed through the ground behind her back after changing the orbit collides with a gas planet, which protected the dwarf before annihilation. After the collision earth 1 from the sun in the orbit of the planet from the sun 3. For a dwarf wandering alongside a gas planet revolves around the sun without fear of collision. Obkrazajac dwarf sun approaching dangerously close to the sun but over distances August. Planet Gas obkrazajac sun she could to sweep away lands but then rapidly approaching the earth to the sun waiting for the passage of the gas giant and again returns to orbit.

32,456 years.....and all planets collided with sun before year 500 :(

Life was on my Planet with 700 years. Got wiped out ay 79000 years.I hope to find out if there are next stages of life in this 'game'

Going to try to get a solar system to last as long as possible. I created a solar system with these specs:

3 Gas planets (not giants). 1 of them has a moon

1 Liquid planet with a moon

1 Earth planet

1 tiny Rocky planet


The Gas and Liquid planets are pretty far from the star with circular orbits. The rocky planet has a close, elliptical orbit around the star. The Earth planet is in a circular orbit between the Gas planets and the Rocky planet.

Good game, fun and strategic. Its difficult to get your solar system to last a while though.

I was able to create the moon to one of the gas giants (busier saying larger body makes less to orbit around it)

Reynaldo Ronquillo

2 planets left. one gas giant in the outer orbit.

one rocky water with life. achieved perfect orbit.

I wish that when you got life it would develop over time and become interplanetary that would be so cool. And, as a part of that, you could monitor your planet and see it's stats for life, what it's atmosphere contains, etc.

yay i develpoed life. the game would be better if you can have moons

I'm only 5000 years into the game and disaster has already struck. An asteroid hit the gas planet with a moon and shifted its orbit. This caused the gas planet to absorb both its own moon and the Earth planet about 500 years later. This messed up its orbit even more. Now the gas planet is drifting all over the place with an erratic orbit and has already had close calls with several other planets. I fear it will take out more planets before its orbit stabilizes.

Cole Snedeker

Another 5000 years have gone by and as I predicted the rogue gas planet caused more damage. A close call with the liquid planet resulted in the liquid planet's moon getting wiped out. In addition, the tiny Rocky plant also fell victim to the rogue gas planet. Currently the gas planet is haphazardly orbiting the star at a close radius with an elliptical-like path. So only 10000 years have passed and I have already lost half of my planets.

Unfortunately, the two gas planets collided at 28000 years through. I didn't even get close to my 1 million year goal, only about 3%. Hopefully my next solar system will fare better.

Cole Snedeker
Cole Snedeker

I'm 20000 years through and already down to two planets. The rogue gas planet collided with the liquid planet. This shifted the Gas planet's orbit again, causing it to crash into the star. Now the only two planets left are the other two gas planets, both of which have broad orbits far from the star. However, they are traveling in opposite directions near each other, so what will most likely happen is they will collide head on.
