I’ve always loved the idea of living on a planet with more in the sky than one Sun and one Moon. Or maybe living on a moon orbiting a beautiful gas giant. Could you imagine the sights?
Tatooine is the sandy homeworld of Luke and Anakin Skywalker, which orbits a binary system consisting of a Sun-like G-type and a less luminous K-type star.
Planets such as these are a rare occurence as far as our discoveries of exoplanets as gone so far. There are over 1000 confirmed exoplanets with only 17 confirmed to be circumbinary.
One of these being Kepler 16b, which orbits a binary star system in the constellation of Cygnus consisting of a K-type star and an M-type star. Both of these are smaller than our Sun.
Kepler 16b is a gas giant, only a little smaller than our Saturn, so finding inhabitants similar to on Tatooine is very unlikely. However, the discover of such systems in our own Galaxy gives the idea that we may one day find such a familiar sight.
On a moon?
In our Solar System, moons are desolate companions to their parent planet. As with all things, there is an exception, one which is most unique compared to the rest.
Titan is the largest natural satellite of Saturn and the second largest in the Solar System, second to Jupiter’s Ganymede.
Titan is most unique as it is the only moon in our System to have an atmosphere; it is rich in nitrogen, similar to Earth, but with a small percentage of methane and hydrogen, with traces of other hyrdocarbons.
It is also the only other world which hosts more than one state of the same element. On Earth, water is seen as solid ice, liquid oceans and water vapour. On Titan, it was confirmed in January 2007 that there are lakes of liquid methane present. These lakes are filled by the failing methane rain from clouds comprising of gaseous methane.
There definitely is not a comparable civilisation living on Titan but the idea of a faint glowing Sun in the day time followed by gazing up at the beautiful rings of Saturn sparks the imaginative creation of a wonderous world.
The film Avatar is a gorgeous example of how our imagination can create such amazing worlds – similar to Titan in the way of life evolving on a moon.
