Omega Prime (HIP 23437 / HD 32778 in 0.9.7.4 beta patch 5) is a human-only colony located 72.5 light years from Earth. It is a temperate E-Class planet in orbit around G5 V type star at a distance of 0.73 AU, perfectly placed within the habitable zone of its star.
There is an entire biosphere of about a million species of plants and animals. More than half of them exist in the planet-wide ocean.
Overview
Omega Prime was first discovered in 2074 by SETI. Soon after, they realized that Omega Prime was a very earth-like planet. Not much else happened in the history of Omega Prime, up until the invention of the Warp Drive.
It was first visited by the ISSAP probe (equipped with a Warp Drive) in June 2375 and sent back the first images of the planet from just a few thousand kilometers away from the Earth-like planet.
In 2386, the first manned mission began. By early 2387, the spaceship had reached Omega Prime and colonized it for the first time. Colonization of the planet had begun with a tiny population of twenty. By 2400, the population had reached a thousand.
Between 2405 and 2408, Omega Prime was one of the targets of the Vaylek terrorist attacks. Amongst all of them, the 2407 Attack was the most destructive of them all. Focusing their attack on the northern hemisphere continent, 2,000 buildings were destroyed.
Environment
The environment on Omega Prime is similar to the Earth. With an average temperature of 6.2 degrees celsius, life on Omega Prime is very Earth-like. However, with a gravity of 0.54 g, animals have thinner legs and appear taller. The tallest trees tower into the sky of about 250 meters and the smallest plant is 1.5 cm tall. The atmosphere has a pressure of 0.85.
Analysis of life on the planet indicates that the life must have been genetically modified by another civilization. Most scientists believe the creators of life on Omega Prime is the First Civilization.
Ancient Civilization: Omegians
The Omegians were an ancient civilization that are believed to existed 123 million years ago, during the Earth's Cretaceous period. It is believed these creatures were always an early-Type II civilization but had never made it to a Type III civilization. Their civilization lasted for 14,000 years until they were destroyed in a war with another civilization. Most scientists believe this other civilization was the First Civilization.
Omegians had developed technologies like Warp Drives, but never constructed Wormhole Drives. It is believed that they colonized a radius of up to 23 light years.
