Terramyde (Red Sun)

Ganymede is the 5th planet from the Sun and the home of the human race. Ganymede formed 4.5 billion years ago and was pushed out of Jupiter's orbit. It is the largest terrestrial planet in the Solar System with a diameter of 12,500 km. Its biospere is a diverse chain of aerobic and anaerobic lifeforms, ranging from single-celled organisms to complex organisms.

Ganymede's outer crust is segmented into different plates capable of shifting over long periods of time.

Atmosphere
Gynamade has a thick atmosphere which helps regulate the temprature around the planet. It is composed primarily of nitrogen, oxygen, and other gases. Its average temerature is 20˚C/68˚F.

Aether
Aether is Ganymede's largest moon, which was possibly once a planet captured by Ganymede's orbit. It has a rugged, mountainous terrain with a thick, nearly planet-wide forest covering the mountain tops. It played a prominent role in early mythology. The result of Aether's strong tug on Ganymede creates unusually high tides in the summer, though they are not dangerous.

Hemera
Hemera is Ganymede's other moon, which is also probably a planet captured by Ganymede orbit. It has flat, fertile soil with lakes and a few mountains. Because Hemera is small moon, it has considerably less tug on Ganymede and also played a prominent role in early mythology. The result of Hemera's tug is that it help counteract some of the high tides in the summer and they are not as high as they could have been with no Hemera.
