Once home to an ancient civilization known as the Tukians, Tukoa is a cool D-Class planet found in an ancient galaxy at about 312 million light years from Earth.

Also known as RS 2146-63-8-5182426-1360 B3 ( beta patch 5).



Tukoa bathed in red light from its brown dwarf sun. A gigantic storm rages constantly on the day side, despite temperatures of -44 C.

Tukoa is a world full of interesting stories to tell. One of the most famous known to most civilizations in the ancient galaxy are the Tukians, an ancient, interstellar civilization. Evolving on Tukoa for almost 15 million years between 450 million BCE and 435 million BCE, they are the most loving and affectionate civilization known to the galaxy.

The planet is approximately 12.4 billion years old. It only formed when the Universe was just 1.4 billion years old. Life first appeared on the planet almost 200 million years after it formed and took another 2.5 billion years until the first multicellular creatures appeared.


The climate on Tukoa is far different from Earth. Although a mega storm appears at the day side, the force that keeps it going for millions of years is the rotation period. Most planets found in the Universe are tidally locked, a phenomena that locks its rotation period to be the same as its orbital period. This creates a very strange environment, one side constantly faces the brown dwarf sun and one side faces away from the sun. A planet with this kind of environment experiences a permanent wind pattern where the wind rises at the day side, travels to the night side and drops and travels back to the day side, creating a constant cycle.


The planet orbits at a distance from its brown dwarf sun of about 7.9 million km, giving it an orbital period (or 1 Tukian year) of 20.3 days. At this distance, it is also tidally locked. It has a diameter of 13920 km, roughly 9% larger than Earth. It has a mass of 0.73 Earth's. Both these parameters give the planet a gravitational pull of 0.61. The planet is orbited by one moon, captured billions of years ago into a highly elliptical and inclined orbit.
