Five Neptunes

 HD 10180 is a sunlike star with five Neptune-like planets and possibly some other planets.  If you have gas-dwelling aliens, you might like to put them here.

There are between 5 and 7 planets orbiting HD 10180, if there's 6 planets then the most probable configuration is 5 Neptune type planets orbiting about from where Mars would be on out and a rocky planet with a mass of ~1.4 earths in an orbit roughly in the habitable zone.

However, the data would also support the less likely configuration of 7 planets, with a Earth mass world in orbit around a smaller gas giant, both of which are roughly the same distance from their sun that earth is...

In other words, we've found Pandora.

I thought of Pandora too. There are also a few other SF stories where the satellite is the setting.
