All the habitable planets and moons in the Nejiro system have experimental farms, resource surveys, scientific expeditions, agricultural and scientific studies of flora and fauna, and/or scientific field studies of everything from geology to meteorology. To safeguard important resources, all manned expeditions have armed security attached to them. There are also several studies being conducted by drones and robotic rovers, many of which are also armed.
Jovian, the seventh planet in the Nejiro system, is a gas giant of mostly hydrogen and helium with four rings and two trojan clusters of asteroids. It also has thirty three moons, two of which are habitable. Tabernas is semi-arid with almost no observable surface water, little rainfall, and sparse surface vegetation. Most of the life on the planet can be found in caverns or caves with access to underground water surfaces (natural wells and cisterns, aquifers, rivers, and lakes). Kilcoole is subartic and largely covered with glaciers. Its average temperature is negative forty six degrees celsius which may drop to lows of negative one hundred twenty eight degrees celsius, or climb to a balmy fifteen degrees celsius during its short summers.
Odin, the tenth planet in the Nejiro system is the largest gas giant in the system with eight rings and forty two moons. Three of these moons are habitable: Nettaiurin is a land-locked world of a thick foggy atmosphere and a humid tropical climate completely covered in jungles, wetlands, rivers, lakes, and rainforests, its wildlife consists mostly of large insectoids, reptilians, and avians, Juichi is a cool arid desert world mostly covered in sands, with an average daytime temperature of fourteen degrees celsius, its mountainous with several inland seas, and Kaiyo is an aqua world with water hundreds of kilometers deep that generates many strong typhoons each year some that cover more than half of the moons surface. There is very little landmass, only sparse 'islands' and atolls that are actually the peaks of sea mountains and volcanoes. Adventurous tourists come here for surfing, diving, and sailing. There are also a few submerged scientific and residential habitats, and several submersible vehicles that conduct oceanographic research and resource surveys.
Midori the eighth planet in the Nejiro system, a green verdant world with an easily breathable atmosphere, large bodies of fresh water, and standard gravity. It is mostly temperate, with a high chlorophyll content in its flora and oceans. But caution, scientists and agriculturists have recommended that any long term stays include water filter supplies and prepackaged food sources, due to the high acid content of the water (average ph of six), and
the heavy metal and mineral presence (mercury, zinc, cadmium, and arsenic) in the soil, flora, and fauna. They also recommend future settlements raise their agriculture in domes.
Glace is the ninth and last habitable planet in the Nejiro system. It is a cold world, mostly
subarctic, roughly three times the size of Terra and classified as a heavy gravity world (1.6g). It is deep in an ice age cycle and glaciers cover more than seventy percent of its surface, including large parts of the salty oceans. A small area spreading from the equatorial plane is glacier free, but is still cold and snow covered throughout the long winters and most of the spring, during which the planet generates a lot of weather systems and enormous storms, due to its twenty eight degree axial tilt and seismic activity. At the equator its mountains are densely covered in coniferous forests and a surprisingly high degree of mammalian fauna. Adventurous tourists come, usually in the summer to challenge themselves on the mountains (climbing, skiing, cycling, camping, and hiking), or to relax and bask on the beaches or sail in the warm summer sun.
