Gallifrey
From FenWiki
Gallifrey (Tau Ceti II) is the only known life-supporting world in the Tau Ceti system. As it stands, Gallifrey's ecosystem appears to be recovering from a Permian-style extinction event; the continents are largely desertified, with the oceans showing signs of rapid anoxia in the recent past.
The Soviet Air Force established an automated weather station on Gallifrey as part of their 2014 Tau Ceti expedition.
