OB-201

## OB-201/I

A-class

Diameter: 2800 km

Estimated age: 2.5 billion years

Ecliptic tilt: 94°

Magnetic axis tilt: 38°

Monitoring of volcanic activity indicates that is roughly 2.5 billion years old, which is somewhat longer than for planetary bodies of this class. Large concentrations of carbon and sulfur dioxide in the planet’s atmosphere and average volatility factor show that the planet will in A-class stage at least another 200-300 million years, before it begins to cool off. Average stellar albedo fluctuates in interval 0.7-0.85, with a steady decreasing gradient stretching from northern to southern geographic pole of the planet. This is in accordance with lower volcanic and tectonic activity of southern hemisphere.

Much like Sol’s Uranus, the planet’s rotational axis is tilted by 94° to ecliptic, while the magnetic axis is tilted by 38° to ecliptic.

What has caused an unusual development of this planet, this close to the home star, remains to be solved. Planet’s orbit, however, seems to be stable and has estimated precession angle less than 2°, with precession period more than 200 000 years.

## OB-201/II

O-class

Diameter: 12 100 km

Estimated age: 4.1 billion years

Ecliptic tilt: 31°

Magnetic axis tilt: 16°

   Jewel in otherwise dreary planetary system. Estimated age of about 4.1 billion years. Water coverage is 88%. It is, in many aspects, Earth-like planet, with rotational and magnetic axis 31° and 16°, respectively, to ecliptic. It has gravity of 0.93G, 27.6-hour day and it takes 1.181 Earth years to orbit the home star. Breathable atmosphere with 20.4% oxygen, 78.1% nitrogen and 1.5% of trace gases.
The planet has unevenly distributed islands, in size range 40 - 1000 km2. There are two islands in the northern temperate zone, partially stretching into subpolar region, which may have been single continenal body in the past. Larger island, roughly 7000 km2 in size, was visited by the away team.

 File:IMG 20190629 135910.jpg   File:IMG 20190629 141046.jpg  The island itself has lush forests, dominated by 3-4 types of tree species, akin to Earth’s birch, island oak, pine and spruce, varying with island’s geographic latitude. Presence of the evergreen-like tree species indicates the possibility of harsher winter periods, even though the planet is, by standard classification, of tropical climate.

Interestingly, aside from several insects, avian and marine species, the expedition did not observe reptile or mammal lifeforms. Amphibians have been detected with a wide bio-tricorder scans near several bodies of fresh water, but not visually confirmed.

Grassland areas are also present on the island, consisting roughly 15% of its surface. Several flower species have been seen. Images are of those brought onboard for further study and possible replanting.

The white flower is particularly interesting. It releases the nectar-like substance to attract the insects, however its thick leaves not housing water, but rather a fluid rich in proteins, such as lysine, usually found in animals. The purpose of this fluid in the ecosystem is yet to be determined, but initial field analysis suggests it could be consumed in raw form.

Due to this unusual plant, the crew has already nicknamed this land mass Eilean Flùr Geal - Island of the White Flower, in Earth’s ancient Scottish Gaelic language.

## OB-201/III

N-class

Diameter: 11 000 km

Estimated age: 6 billion years

Ecliptic tilt: 11°

Magnetic axis tilt: 0°

Roughly 6 billion years old, could be a former rogue planet. Volcanically inactive, tectonic activity minimal also. Planet does not exhibit any peculiarities outside of its class. Tilt of rotational axis is roughly 11° and magnetic axis is almost 0°, excluding the fluctuations.
