Gesar System

Gesar system has 2 life sustaining planets.

After the sun and asteroid belts is the first planet
Askais, with large warm oceans, harsh weather, giant mangrove like forests and a frozen moon, Arken. The air is much richer in oxygen and some heavy gasses, but scans do not indicate any toxic gases.

The next planet is farther from the sun, with large tundras and cold climate forests, and a few harsh deserts where there is not enough rainfall to support forests. Exploration teams should remember that not all deserts are hot, dress for cold weather. A breathing mask is also required, because the air is toxic after long periods of inhalation.

Then farther out into the system there is a large gas giant, Gargun, with a large collection of moons. (not shown in this reconnaissance picture). The moons are the remnants of any planets and space debris that crossed into the gas giant's gravity well.
