At the heart of an unusual rectangular planetary nebula, lies Tanga System. The inner planets were engulfed when the star entered it's red giant phase. The expanded habitable zone unfroze a small world on the former outer ring and for several hundred million years made it habitable.
Life began to emerge and was just reaching a primitive state when the star collapsed into a white dwarf, throwing the planet back into a deep freeze, then blasting the atmosphere away with the resulting planetary nebula.
That’s how the system was found: Only two worlds (speculation that there could have been three to four more) but both are dead planets with no atmosphere.
Miners have found a variety of precious and heavy metals in its asteroid belt and believe the resources to be remnants of Tanga's inner planets.
Tanga I Edit
A former gas giant that scientists believe has lost its atmosphere when Tanga's star turned into a red giant. The remaining core is classified as a chthonian planet and is rich in heavy minerals.
Tanga II Edit
A planet subliming due to the systems high temperature. As a result, a trail of gases follows Tanga II around in orbit
