Probably due to its small size (it is only a few hundred kilometers smaller in diameter than Mars), it has lost most of its major oceans over the eons. The planet has lower gravity in addition to its atmosphere, allowing for organisms to get much larger than what is possible on Earth. In both the book Expedition and the documentary Alien Planet, Darwin IV is the first planet with complex life explored by humanity and where most of the events in both media happen.Ĭompared to Earth, the planet has far less surface water being only 5% covering the surface, which is mostly locked by the Amoebic matrix, and the rest of the water is found in the atmosphere, as well as in the polar caps and subterranean aquifers that protrude across the planet as small puddles. With a very dense atmosphere and little gravity, it is home to a large number of complex organisms characterized by lack of eyes and rely mainly on echolocation and infrared vision, with different and aberrant forms and sizes. Small water bodies, the largest body of water is covered by a major superorganismĭarwin IV is a small desertic rocky planet, the fourth planet in the Darwin Binary System formed by 6 planets, is 6.5 light years away from Earth's Solar System. Oxygen-rich (too much for human breathing)ĭeserts and mountains, with a few areas of vegetation Darwin IV from the Documentary Alien Planet
