The planet name (latin for Red Home) was given to it after the only native spieces of the planet: a red proto algae, an oxygen-productor that resembles that of Earth's but works on chemical energy instead of solar. The planet was discovered in 2099 and first explored in 2139, but the terraforming process was begun in 2152 and finished in 2161. When the planet was first discovered, it has characteristics similar to those of Earth 4 billion years ago. Travel time to*:
