Building on "SolarSystem", this game adds a gas giant that influences the small blue planet. Can you make a stable system? How long will life survive in your system? Post your High Score ... The simulation starts with SBP in a nearly circular orbit; Click on the gas giant, and use the cursor to set the direction and velocity you want to launch at, then click again to launch.. It's interesting to see how a gas giant eventually "clears" its orbit of debris like the small blue planet. I've even seen the SBP to orbit the Gas Giant for several simuluation "years" before the "end".
