OB-930 Ravenealla

OB-930 Ravenealla is a binary star system consisting of one yellow dwarf OB-930-A (spectral type G2V, much like Sol) and a red dwarf OB-930-B (spectral type M6V) that orbit in a elliptical pattern around the common center of gravity. There are 4 planets, 2 of which are Class-M. All planets are circumbinary, meaning they orbit both starts at the same time. It is a home system of Ravenea people and their polity - Garden of Ravenea.

## OB-930/I

C-class

Diameter: 8700 km

Estimated age: 5.2 billion years

Ecliptic tilt: 21°

Magnetic axis tilt: 7°

A barren world, constantly bombarded by intense radiation from the two starts. The gravitational disturbance is causing a 3000 years precession period, as well as the nutation of planet's rotational axis. It is mineral rich, but no mining operations have been attempted due Ravenea's technological inadequacy for the project of that scope.

## OB-930/II

H-class

Diameter: 11300 km

Estimated age: 4.6 billion years

Ecliptic tilt: 2°

Magnetic axis tilt: 16°

Predominantly a dry, desert world with the orbit lying on the inner edge of habitable zone. There is a substantial evidence the planet was inhabited by complex plant and animal life in its past, but went it extinguished at least a 2.5 million years earlier. Radioactive analysis of atmosphere composition, geological surveys and continuing observation of stellar activity of the binary star system show the planet was hit by an intensive solar flare which stripped off majority of planet's atmosphere. This most likely caused extinction of life due to deep UV light exposure, but also increased day/night temperature oscillations, eventually turning the planet into lifeless husk. Planet has one D-class moon, diameter of 300 km, in a stable orbit.

## OB-930/III

M-class

Diameter: 13200 km

Estimated age: 4.8 billion years

Ecliptic tilt: 6°

Magnetic axis tilt: 26°

Close to the middle of the habitable zone, a lush jungle world teeming with life. Inhabited by almost 9 million different species, of which ~10% are plants. Planet is ~41% covered by land, divided into 4 major land masses. Dominant land animals are reptiles and mammals. The planet is being extensively explored by Ravenea, who have began colonizing the smallest landmass in 23rd century AD.

## OB-930/IV

M-class

Diameter: 12100 km

Estimated age: 5.5 billion years

Ecliptic tilt: 19°

Magnetic axis tilt: 5°

The homeworld of Ravenea. Around 53% or surface is covered by land, divided into 5 major land masses. Inhabited by 26 million species, of which 21% are plants (of that 7% are trees and shrubs). Dominant land animals are fish, amphibians and reptiles, with mammals consisting of few endemic species on the fourth largest continent. Proto-Raveneans appeared on four larger, southern continents almost 25-28 million years ago. Interestingly, each of the four continents has two unique features - ancient forests, which became nurseries, and what Raveneans called Trees of Life, from which Proto-Raveneans developed. Each pair genetically deviates slightly from continent to continent. Trees of Life are even older, with their age being estimated to range of 30-38 million years. There are indications these Trees possess some rudimentary sentience, but the results of scientific investigations have been inconclusive thus far.

There are signs that the fifth land mass also housed another Tree of Life, but many Raveneans believe the Fifth Tree or The Lost Tree was somehow scooped off the planet.

## OB-930/V

A class J giant, estimated age is 4.1 billion years. No rings, contains 36 moons, most of of them D class, two are C class. The gas giant is of cultural and scientific importance to Raveneans since it is the sight where they encountered first non-Ravenean species - a pod of Purgills. Observations of Purgills led to the development of Ravenean bio-warp propulsion. Although the Purgills have not been seen in the system since the initial encounter, the fifth planet is off limits for all traffic, exploration and mining activity. Raveneans justify this decision by stating the fifth planet is "someone else's home and it should not be interfered with".
