Conversion was the second terraformed planet in Achenar. Still less massive than Earth, it has a relatively similar gravity and atmospheric pressure. However, due to the 1.3% water atmosphere, the climate is highly tropical with an average temperature of 317 Kelvin (43 Celsius). It orbits the gas giant Achenar 6 in about 230 Earth days, while a day on Conversion lasts nearly 48 hours. The service Orbis station, MacMillan Terminal is found in orbit of this planet.
