Tucana Star System

Type:	K6V Orange Main Sequence
Radius:	5.89 x 10⁵ (0.86 Sol)
Mass:	1.38 x 10³⁰ (0.70 Sol)
Temperature:	3900 K
Luminosity:	5.88 x 10²⁵ (0.15 Sol)
Ecosphere:	0.3 to 1.3 AU
Location:	Beeria Sector 3 ly from the Hubroid Star System 4 ly from the Tau Majestius Sector‎

The Tucana star system, located in the Beeria Sector, consists of four planets. Tucana Prime, a K-Class planet, is approximately one-third the size of Earth with a thin atmosphere. Microbes and fungi have naturally evolved on this planet, which is 67% covered in water, with half of it frozen at the poles. Tucana 2, a P-Class planet, shares similarities with Earth in terms of size and gravity but is too distant from Tucana to become a Class M world. It features a glaciated surface with pockets of liquid water beneath the permafrost. Tucana 3, a rare Class V "Super Terrestrial" planet, has a powerful magnetic field, liquid water covering over 68% of its surface, and a diverse ecosystem. Tucana 4, a C4-Class planet, is cold and barren, with a tenuous atmosphere primarily composed of helium and hydrogen. Although it shares similarities with Earth in size and gravity, its distance from Tucana hinders meaningful terraforming efforts.

Tucana Prime

Class:	K
Distance:	6.91 x 10⁷ (0.46 AU)
Period:	137.1 Days
Radius:	3,953.68 km (0.62 of Earth)
Gravity:	0.52 G

Tucana Prime is about 1/3 of the size of Earth with a thin and steadily reducing atmosphere. Currently microbes and fungi have evolved naturally on this planet. Water covers 67% of the planet surface with 50% of it frozen starting at the poles. The core is mostly composed of iron and silicate, which helps to explain the low gravity. Eventually this world will likely reduce to a Class C once most or all of the atmosphere has escaped into space. This world is promising for colonization either by terraforming or the use of pressure domes.

Tucana 2

Class:	P
Distance:	1.06 x 10⁸ (0.71 AU)
Period:	260 Days
Radius:	6,254.34 km (0.98 of Earth)
Gravity:	0.91 G

This world shares many similarities with an M Class world but did not follow the same evolutionary path. Despite being similar in size and orbit to Earth, a past event caused it to become a frozen, glaciated world. The planet's surface is predominantly covered in ice, with liquid water trapped deep within the permafrost. Tectonic activity provides shelter for simple single-celled organisms and bioluminescent algae. The planet has four small asteroidal moons in orbit. Due to its orbit and similarities to Class M worlds, there may be a possibility of terraforming this planet. The mean temperature is around -60 degrees Celsius, and the atmosphere is dense, consisting mainly of nitrogen, helium, and oxygen, with minimal amounts of carbon dioxide, methane, or other greenhouse gases to retain heat.

Tucana 3

Class:	V
Distance:	9.57 x 10³ km (0.94 AU)
Period:	1.09 Years
Radius:	10,135.90 km (1.59 times Earth)
Gravity:	1.35 G

Tucana 3, known as a rare "Super Terrestrial" Class V world, possesses a core composed of iron and super-dense rare-earth metals, resulting in an exceptionally powerful magnetic field. The planet's surface boasts liquid water covering over 68% of its area, with only 12% frozen at the polar regions. The atmosphere is predominantly carbon dioxide, fostering the evolution of diverse pressure-resistant plant and animal species. However, the thick atmosphere gives rise to frequent extreme electromagnetic storms in the stratosphere, posing hazards for landing. Notably, near the equator of the smallest continent, there is evidence of a crashed starship, potentially the USS Ascendant Ignition (NCC-1943), an early Starfleet exploratory vessel ensnared by the planet's atmospheric conditions.

Turcana 4

Class:	C4
Distance:	1.45 AU
Period:	3.51 Years
Radius:	6,466.94 km (1.02 times Earth)
Gravity:	0.99 G

While Turcana 4 is similar in size and gravity to Earth, it's distance from Turcana makes it a cold and barren world. There is a tenuous atmosphere, though it is minimal composed mostly of trace amounts of helium and hydrogen. It is composed of anthracite and basalt, typical to a Class C would, though it is larger than average for such a world. The Earth-normal gravity does give promise for colonization using pressure domes. Unfortunately the world is too far from Turcana, given it's luminosity, to be terraformed in any meaningful way.
