Mortia

= Mortia =
Mortia is the innermost planet of the Patria Binary System. It is the third most massive of the system's five terrestrial planets and by far the hottest of the five. Its name is Latin and means "death."
== Physical Characteristics ==
Mortia is primarily composed of iron and silicate rock. It's gravity and density are fairly average for a terrestrial planet. Its surface is covered with volcanoes flooding the area around them with molten lava and spewing carbon dioxide, hydrogen sulfide, and sulfur dioxide into the atmosphere. It is by far the most geologically active planet of the system.
== Atmosphere ==
Mortia possesses a thick greenhouse atmosphere composed primarily of carbon dioxide. This atmosphere is so thick that it's impossible to see the two stars in the sky, as an observer would only be able to see endless yellow-orange clouds everywhere. The pressure on the surface is also deadly to must carbon-based life forms. Due to the greenhouse atmosphere trapping insane amounts of heat, temperatures on this planet are very stable at 750 K, even during the night. 
== Orbit and Rotation ==
Mortia orbits the two stars at an average distance of 0.96 Astronomical Units (144,000,000 km / 90,000,000 mi). It takes about 240 and a half days to complete a single orbit around the two stars. Interestingly, the planet itself only needs 6 hours to rotate around its own axis once, meaning that in local days, a year on this planet takes about 962 days.
