Discovered the same time as Cassiopeia Prime (as they are in the same system) the cool O-Class world was named by one of the first colonists to “land” on the surface. It is said that as the first crews surveyed the waves, one of them jokingly said the old Earth word of 'Cowabunga'. Another colonist jokingly implied that it could be the name for the planet. This humorous conversation went farther than expected, and ended up being the name of the planet.
Lifeless and cold, the planet was not a high prospect for terraforming, but in the beginning it could be used to introduce water to its sister planet Cassiopeia Prime. The core of the planet also was rich in heavy metals that could be mined if done carefully. Slowly the planet shrunk and the gravity lessened. Massive domed cities were built on the water where the miners could live.
When mining was no longer viable, the cities remained. Then the idea of terraforming came to the inhabitants. Over the next few decades, the planet was warmed and seeded with terrestrial sea life. Soon the planet became a garden water world with massive artificial islands.
Currently, the planet hosts over 12 million inhabitants, mostly descendants of the miners or of the colonists from Earth’s own tropics, which came after terraforming was completed. There is little government on the planet as the locals are playing the hosts of incoming vacationers who enjoy swimming, surfing and generally enjoying the beach life.
On its discovery it had a diameter of 26584.5 km, the world has a gravity index of 1.6 G. It has an AU of 2.3 giving it a local year of 3.5 terrestrial ones. It had an atmosphere of 2.1 and a mean temperature of -34.4 °C. The planet has eleven moons, four of which are globes.
After some of the ocean was siphoned off for the use in terraforming Cassiopeia Prime, the gravity lowered a bit to Earth norm. The deep sea mining also helped to reduce the gravity. After that the introduction of greenhouse gasses alongside terrestrial sea life warmed the planet considerably. Soon it became a warm vacation planet.
