Nispe

Nispe (formerly called Planet) is the fourth planet in a recently discovered and yet to be named star system. Located on the further edge of the habitable zone, it's been discovered to harbour complex lifeforms.

### **Astronomy**

Nispe is located on an orbit sufficiently close enough to support liquid water, despite tending more to the outer region of it's solar system; therefore it's surface temperature usually ranges from 0 to 5° Celsius (aside from rare warm ages which will bring the planet closer to the sun). it's diameter is around 6800 miles, making it just slightly smaller than earth and thus possesses a lower gravity. during the Cloacian, the passage of a jovian gas giant brought the orbit closer to the sun, rising it's temperature to around 20° C and offering a great environement for life to further develop. the sun's relatively stable characteristics allow little interference in it's atmosphere and magnetosphere. it has a regular day/night cycle of around 19.57 hours (as for the Chodician), and has an axis tilt of 25°, slightly more pronunciated than earth's. it possesses two moons, one big as much as 1/5 of the planet's diameter, notably composed for a large part of iron and other minerals due to it's origins, and a smaller, more conventional-looking one. while these have had a bigger tidal force on the seas once, that has weakened overtime as both moons started to get further from nispe.

### **General Characteristics**

Nispe is slightly smaller than earth by a 14% difference, meaning it has also a smaller gravitational force (albeit not much different). atmosphere and geological composition are similiar to earth, with a slightly higer oxygen concentration. however, the ozone layer, which formed during the chodicene, is slightly weaker than that of earth, so life on the surface may take additional adaptations to protect themselves from uv lights . volcanism is active and intense, meaning earthquakes and volcanic eruptions (as well as continental drifts) are frequent. this also spreads many chemical and mineral substances across the seas, contributing to the development of life underwater; however, in some occasions, catastrophic volcanic phenomenons can happen, putting the sea's population at risk like in the B-CH extinction event. much of the boreal hemispheres are covered in permanent and semi-permanent ice sheets, which can periodically extend further during ice ages, like the mid-orchidian one that covered almost half of the planet's surface.

#### **Geography**

Nispe currently possesses two continents, called Labia and Sigoglia. While the latter continent has not yet developed a proper ecosystem, the former possesses a wide range of lifeforms; Labia is divided into two sub-continents (Holea and Panspermia, from the names of the continents that form it), as well as a vast, central lake, remnant of a sea engulfed during the continent's formation. the seas of Nispe are also separated both ecologically and geographically; the northern hemisphere possesses shallow and lively oceans, while the southern is much deeper and harsher. further information about the subject can be found in this page.

#### **Biosphere**

Life is greatly abundant on Nispe, evolving first in the Cloacian and with multicellular life evolving shortly before the Benician. but only after the start of the warm age there has been an explosion of biodiversity, where life diversified in countless species and forms, marking the start of the era along with the climate change. during the Chodician, life also managed to emerge from the seas thanks to the development of the ozone layer, with multiple genres and lifeforms evolving to adapt to live on rivers and shores independantly. life probably developed throught a mixture of panspermia, with vital organic chemicals arriving to nispe throught meteors, and underwater volcanic activity that allowed the formation of amminoacids similiarly to earth. despite this, it has a similiar chemical composition to the latter, being carbon-based and oxygen-breathing. thanks to the chemical activity of volcanism in the seas, many creatures (and plants) are easily capable of integrating and producing shells and hard organs.
