A New Galaxy

Planet Earth is dying. It was found out that earths resources was low and the core was getting reactive to the point, where the planet had a potential life span of thirty years.

NASA decided that they would send six groups of atronauts to find potential habitable planets. Three of the six teams found planets that were livable, however there was a catch. Each planet had an age limit and would only take those with no criminal record.

The planets are;

Planet 1;
Name; Dayko
Age Discrepancy; 31 - 90
Description Of Climate; Similar to earth, however it days are 36 hours long. It's years are 9 months long with only three weeks per month. A weeks is five days.

Planet 2;
Name; Bluhua
Age Discrepancy; 0 - 45
Description Of Climate; Underwater dome colony/system. The temperature underwater is livable however the air above the water is toxic to the human body. There are multiple dome colony's. The days are 24 hours, however the years, weeks and months are shorter.

Planet 3;
Name; Sunakai
Age Discrepancy; 16 - 60
Description Of Climate; Hot temperatures the lowest being around 15°c, the highest being up to 45°c. The towns and small cities are spread out as the whole planet is a desert. There is only one waterhole and that provides water for drinking. The entire galaxy all orbit the sun very closely. The days are long with most being 24 hour a day, but they are very long 24 hours.
