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)
Location:	Beeria Sector 3 ly from the Hubroid Star System 4 ly from the Tau Majestius Sector‎

The star Tucana has 4 planets, one of which could be adapted for colonization.

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 is similar to Earth in size and gravity but is too far away from Tucana to have developed into a Class M world. The surface is nearly entirely glaciated, though liquid water exists it is deep within the planet's permafrost. Tectonic activity does provide some safe haven for simple single-celled organisms and some forms of bioluminescent algae. There are 4 small asteroidal moons in orbit.

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 is a rare example of a Class V world, so-called "Super Terrestrial" the core is composed of iron and super-dense rare-earth metals which give the planet an unusually powerful magnetic field. The surface has liquid water over 68% of the surface with only 12% of that frozen at the poles. With an atmosphere dominated by carbon-dioxide, oxygen, and hydrogen have allowed for the evolution of a wide variety of pressure-resistance plant and animal varieties. The atmosphere is thick and extreme electromagnetic storms are common in the stratosphere, making landing hazardous. Near the equator of the smallest continent is evidence of a crashed starship, possibly an early exploratory vessel. Markings indicate it could be an old Starfleet vessel that got caught in the planets atmosphere.

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.
