Surface Features:
Cite is a young rocky planet with a diameter around the size of Mars. It is a heavily cratered world with many impact sites over 100 km in diameter. Smaller impact sites were probably much more numerous in the past but they have since eroded away. Water covers roughly a quarter of the surface, with most of it located in craters, thereby retaining the majority of Cite's habitation near them. Life is quite abundant on Cite, only the vast expanses of desert seem devoid of fauna. The seasons on Cite change relative to the rainfall received throughout the year as its axial tilt prohibits significant change in sunlight received on either hemisphere. Life on the surface tends to concentrate around static bodies of water across the planet, with many animals never leaving their respective area for the majority of their lifetime. The absence of plate tectonics and volcanism has left the surface mostly unchanged with exception to any erosion that takes place. The oldest standing structures on Cite are the many mountains that conquer the vast deserts, many of which are believed to be the same age as the planet itself. The rest of Cite is quite flat and uniform, with only the odd crater and valley interrupting a seemingly endless desert. Unlike many habitable worlds, Cite began boasting multi-cellular life forms very early on in its history, only 2 billion years after its birth. Fossil records have shown that multi-cellular life forms began to appear across the planet almost immediately after oxygen levels rose above 7% , first within water filled craters then expanding to the rest of the planet. Not surprisingly, most animals seen today on the planet have remained unchanged for billions of years, many of which have developed a specialization to a single portion of the planet, not found anywhere else. Despite this, a few creatures have extended their range across the planet, regularly migrating when food becomes scarce. Many of them are predators, although a few grazing creatures have also taken steps to encompassing the planet.

Internal Structure:
Cite has been geologically dead for around 3 billion years now, with only a minute liquid core remaining. It provides just enough of a magnetic field to block all but the most powerful solar radiation from reaching the surface although it has been steadily been getting weaker by as much as 10% per 100 million years. It is relatively porous, with many pockets of air in excess of a few kilometers in diameter regularly placed within the crust. This has in the past created quakes when an air pocket near the surface collapses, however this happens quite rarely. The crust is quite thick at an average thickness of 60km across the planet. The mantle of Cite is still quite porous although not nearly as much as the crust is. Pockets of air and magma have been detected within the mantle, but are quite small and unevenly distributed, so they produce minimal risk to the surface above if one were to collapse. Cite’s core is extremely tiny, less than 700 km from side to side. It is entirely molten and spinning at a rate many times greater than Cite is, rotating nearly 7 times in a day. Cite’s core has been shrinking at a rate of 70 meters per million years and it will become solid probably within the next billion.

Atmosphere:
Weather on Cite is almost absent. Clouds regularly form and rain across the planet but only in very small intervals. This is one of the reasons Cite’s life is located only near bodies of water, as the vast deserts around them receive absolutely zero rainfall for many thousands of years. The amount of oxygen in the atmosphere can vary between 15% and 25% every few centuries, mostly due to wildfires that engulf the planet and persist for many months. Cite’s overall climate however is very stable, the past 600 million years has had nearly no change in temperature, only dipping every now and then from periodic asteroid impacts that release dust into the upper atmosphere, though most of the dust escapes Cite entirely due to the planet’s low gravity. Although Cite is well outside the “Goldilocks” range of its parent star, an abnormally large amount of greenhouse gases have kept the planet from freezing solid.

Orbit and Rotation:
Cite has a very circular orbit, only varying by one hundred and seventy thousand kilometers from its farthest point, to its closest. Cite’s orbit has near zero inclination, deviating less than a tenth of a degree. Cite’s rotation is quite average, rotating on its axis every 26 hours.

Cite has two natural satellites, one of which is a captured body.
