Note: The spoilered sections contain the "TL:DR". The more scientific details of the Star and planets.
Star Name: Delta Cerasi
Star Type: G-Type
Approximate Age: 3.2 Billion years
Estimated Total Lifespan: 9.7 Billion
Absolute Magnitude: 4.95
Surface Temperature: 5,835 Kelvin [5561.85 Celsius, 10043.33 Fahrenheit]
Core Temperature: 10.5 - 22.5 Million Fahrenheit [ 5.8 - 12.4 Million Celsius/Kelvin]
Coronal Temperature: 1.6 - 2 Million Fahrenheit [ 888 k - 1.1 Million Celsius/Kelvin]
Solar Mass: 1.02 M☉
Planet Name: Cerasi Prime
Planet Class: Y
Distance: .5 AU
Satellites
Trojan Satellites
Diameter: 7, 382 km
Axial Tilt: 11 Degrees
Planetary Day: 31.4 Hours
Orbital Year: 214 Sol III Standard days
Atmospheric Chemistry:
67.3% Carbon Dioxide:
33.6% Nitrogen
165 PPM Sulfur Dioxide
35 PPM Water Vapor
25 PPM Carbon Monoxide
Other Volatile chemicals exist in quantities below 1 PPM *
Variable Quantities of Mercury found throughout the Atmosphere
Surface Composition:
100% Continental
Environmental factors prevent the existence of oceans, though “Lakes and rivers” of Liquid Mercury exist.
Seismic Activity: Extreme
Average Surface Temperature: 319.85 Celsius
Trojan Satellite 1: 9.8 km [6 miles]
Trojan Satellite 2: 6.8 km [4.2 miles]
Trojan Satellite 3: 4.3 km [2.6 miles]
An abundance of mercury creates silvery lakes and rivers that flow across the surface as water would were it not vaporized instantly. The conditions and the presence of mercury and sulfur elements and compounds also allow for a rare phenomenon, even among the Demon planets. The temperature is sufficient to allow both liquid and gaseous mercury to exist, and therefore interact with the sulfurous gases. At surface level, they briefly create solid mercury sulfide before the heat returns them to their original states. At higher altitudes, it cools to liquid state temperature and falls as rain does, though more sparsely. In essence, a mercury cycle exists almost as a water cycle would on an M class planet.
The “Demon” classification is reserved for planets with exceptionally hellish conditions, this planet is no exception.The thick, roiling cloud layer obscures the rapidly changing surface from orbit. Permanently active volcanoes fuel the deadly atmosphere and create new rock layers, while acid erosion and frequently violent earthquakes tear apart surfaces both old and new. Topographical data must be updated frequently.
In orbit of the planet are three asteroids that at various points in the planet’s history were caught in the gravitational pull. All three are in unstable, gradually decaying orbits that will eventually bring them into a collision with the planet. The largest of these is nearing such a point and may begin a descent through the atmosphere at any given time.
Planet Name: Cerasi Beta
Planet Class: L
Distance: 2.7 AU

Ring System
Class D Planetoid (Cracking Station 47)
Diameter: 8,478 km
Axial Tilt: 32.5 Degrees
Planetary Day: 20.2 Hours
Orbital year: 743 Sol III Standard days
Atmospheric Chemistry:
77.7% Nitrogen
10.3% Oxygen
6.1% Carbon Dioxide
0.9% Trace Gases
Surface Composition:
67% Oceanic
33% Continental
Seismic Activity: Moderate
Average Surface Temperature: 9.4 Celsius [49 Fahrenheit]
Multi-cellular Lifeforms present:
Complex Aquatic and Terrestrial Photosynthetic life
Complex Aquatic and Terrestrial Fungal Life
Class D Planetoid
Diameter: 2,793 km
Orbital Time: 24.6 Sol III Standard days
Rotational Time: 34.3 Hours
Atmosphere: Negligible
Summary:
Though a cold rock on the far reaches of what would be considered habitable, life eeks out an existence. The shores of the oceans in the tropics are green hued from orbit as primitive plant life makes a slow migration inland. The oceans of the summer facing hemisphere are often bright green with algal blooms that come and go, taking every advantage of the warmer climate before they return to the planet’s frigid winter. At the poles, gleaming white layers of ice reach over the land, and seem to end in visible islands of ice over the oceans.
Circling the planet is a rough, but distinct band of rings that are the product of ancient collisions of asteroids and satellites alike. The sole survivor of these collisions is a small, cratered moon upon which sits the visible superstructure of Cracking Station 47. Though desolate and hostile to organic life, the dead rock bears a rich bounty of valuable resources such as dilithium that are worth braving the near vacuum to obtain.
Planet Name: Cerasi Gamma
Planet Class: J
Class J Planet/Class 2 Gas Giant
Distance: 7.8 AU
Satellites
Starbase 146 & Facilities associated
Diameter: 108,370 km
Axial Tilt: 3.7 Degrees
Planetary Day: 11.3 hours
Orbital year: 26.5 Sol III Standard years
Atmospheric Chemistry:
Water Vapor
Methane
Hydrogen
Helium
Atmospheric Temperature: 239 Kelvin [-34.15 Celsius]
Summary:
A massive blue sphere from which the parent star is but a glaring point of light. It bears a vague similarity to an M class planet as white clouds drift and swirl over a cerulean sea of gases resembling a vast ocean. A spectacular view to behold from the orbiting starbase which the 146th support fleet calls home.
