Yar

Yar (Centauri II), is a sparsely populated terrestrial world that was terraformed by the UEE. With most of its surface covered by the arid red desert, the planet is a stark contrast to Saisei's natural and constructed beauty. Most of the civilian settlements were abandoned once mineral resources were exhausted. Now the terraformed planet's remaining inhabitants reside mainly in research stations.

Its proximity to the sun makes for an arid environment, and the planet is largely covered by the Red Desert, decidedly its identifying feature from orbit. Yar is dotted with research stations, commercial layover points and abandoned settlements, many of which are coated in the planet's fine red sand (and a significant number of which are being reclaimed entirely by the Red Desert). Although it's not quite a ghost planet, many visitors report being left with a sense of unease among its abandoned facilities. Why is there development in the first place? Yar underwent an unexpected land grab roughly a century ago after valuable precious minerals were located in a mountain range. These claims petered out quickly, and Human civilization on the planet has been in a clear decline since.

Archibald Station
The world's largest landing pad is Archibald Station, a scientific outpost that grew into a small town and then shrank back to an outpost as interest in the planet waned.

Landing zones on the planet continue to remain functional, although unmaintained. Enough infrastructure remains on the planet to support passing spacecraft, although the small population needs only essentials from traders.

Development History
First descriptions of Yar stated that it had been a Venusian world that was terraformed by the UEE. This designation was not present in later descriptions. It has since been asserted that Venusian worlds and other smog planets are beyond the technology of 30th Century terraforming.
